Terms of Service

Last updated: 24 July 2026 · Operated by Neosphere Inc., a Delaware C-Corporation

These Terms of Service (the “Terms”) govern your access to and use of the D6N marketplace, the d6n.ai website, and related software, tools, and services (collectively, the “Service”). The Service is operated by Neosphere Inc., a Delaware C-Corporation (“D6N,” “we,” “us,” or “our”). By accessing, browsing, listing on, buying through, or otherwise using the Service — whether as a human user, as an AI agent acting on a human user’s behalf, or through any authorized interface — you agree to these Terms. If you do not agree, you must stop using the Service.

Read this first. D6N is a marketplace. We connect buyers and sellers, facilitate transactions, and support fulfillment, returns, and refunds. D6N does not create or warrant seller-listed goods or data; sellers remain responsible for their listings and fulfillment. Section 17 and Section 19 explain the limits of our role and liability.

1. The Service

D6N is a categorized listing marketplace for agent commerce. Sellers list items in one of the following listing categories:

Data — datasets, indices, training corpora, structured information, files, and other digital information assets.
Physical Goods — tangible items that must be shipped to the buyer.

Buyers may be human users browsing the Service directly, AI agents acting on behalf of a human user, or registered organizational accounts. Buyers transact using payment methods supported by D6N.

D6N reserves the right to add, remove, or modify listing categories, payment methods, and platform features at any time.

2. Eligibility

You may use the Service only if you:

Are at least 18 years of age, or the age of majority in your jurisdiction, whichever is higher;
Have the legal capacity to enter into binding contracts;
Are not located in, ordinarily resident in, or organized under the laws of a jurisdiction subject to comprehensive U.S. sanctions or any equivalent restriction; and
Are not prohibited from using the payment services available through D6N.

Sellers must additionally be eligible to receive payouts through D6N’s designated payment provider and complete any required identity or business verification.

The Service is not intended for children under 18. We do not knowingly permit anyone under 18 to create an account, list, buy, or otherwise transact on the Service.

3. Accounts and Credentials

You are responsible for maintaining the confidentiality of your account, API, agent, and transaction credentials. You are responsible for all activity that occurs under your account, including activity performed by any AI agent you authorize. You agree to:

Provide accurate registration information and keep it current;
Promptly notify us at support@d6n.ai of any unauthorized use or suspected compromise of your credentials;
Not share, resell, or sublicense your credentials except to AI agents and tools you have authorized to act on your behalf.

4. Geographic Availability

D6N is offered worldwide, subject to local law. Payments and payouts are subject to the regions, currencies, and requirements supported by our payment providers. Some categories, including Physical Goods that cross customs borders, may be further restricted by the seller, by law, or by D6N. We may, at our sole discretion, suspend or limit access from any jurisdiction at any time.

5. Buyer Terms

5.1 Binding purchases

Submitting or confirming a purchase through any supported interface is an offer to buy that becomes binding when the order is confirmed. Before confirmation, the buyer is shown the applicable total. Once confirmed, you owe the listed price plus any applicable taxes, fees, and shipping charges disclosed for the transaction, subject to these Terms.

5.2 AI agent buyers and the authorized-agent doctrine

You may authorize one or more AI agents (whether operated by you, by a third-party agent platform, or by D6N) to act on your behalf on the Service. You agree that:

Any purchase or other transaction initiated by an AI agent using authority or credentials you supplied is an act of your own authorized agent and is binding on you, regardless of whether the agent acted in error, exceeded your instructions, misunderstood your intent, or selected the wrong listing;
You are responsible for all charges, fulfillment commitments, taxes, fees, and other obligations disclosed for such transactions;
Any remedy for an agent-error transaction is the same as the remedy you would have if you had made the purchase yourself — that is, the refund, return, and deadline rules in Sections 8, 9, and 12 of these Terms;
You will configure appropriate permissions, spending limits, and other available controls before authorizing an agent;
You will not authorize an agent to make purchases on behalf of any other person without that person’s authority and a lawful basis.

If you believe your credentials have been used without your authority, notify support@d6n.ai immediately.

5.3 Buyer obligations

Provide accurate shipping, delivery, and contact information;
For Physical Goods, accept delivery within a reasonable time and inspect the item promptly;
For Data listings, use the purchased asset only within the scope and license terms disclosed by the seller;
Not initiate chargebacks for transactions that should instead be handled through the return, refund, or order-support process in Section 12.

6. Seller Terms

6.1 Payment onboarding and payouts

To receive payouts, you must complete the onboarding required by D6N’s designated payment provider, which may include identity, tax, and bank-account information. Payouts may be delayed, withheld, adjusted, or reversed where required by law, the payment provider, or these Terms, including for returns, refunds, disputes, or amounts you owe.

6.2 Listing accuracy and lawfulness

You represent and warrant that every listing you publish is accurate, lawful, current, and that you have all rights necessary to sell it. Listings must not be misleading, must use the correct category and provide all required information, and must clearly disclose any material restriction (region locks, license scope, sub-licensing limits, etc.). You are solely responsible for the goods, content, or rights that you list, and for honoring every term you publish.

6.3 Fulfillment commitments

By listing on D6N you accept the following baseline fulfillment commitments. Failure to meet them may cause the order to be cancelled or refunded, may create a seller charge or penalty, and may reduce your standing on the platform.

Category	Baseline commitment	If you miss it
Physical Goods	Provide the required shipping information and hand the parcel to the carrier by the displayed ship-by deadline. Preparing or uploading a label without carrier acceptance does not satisfy this commitment.	The order may be cancelled or refunded and you receive no proceeds. If a label has been generated or uploaded, D6N also applies the no-ship penalty and any shipping charge or credit described in Section 7.3.
Physical Goods (returns)	After an eligible return request, the buyer must hand the return to the carrier within the displayed return-shipping deadline. Seller-funded return coverage, when available for the order, covers the buyer’s return shipping.	If the buyer does not ship the return in time, the order may complete without a refund. A timely return may be refunded under Section 9.1.
Data	Provide the purchased asset promptly after the order is confirmed.	Buyer is entitled to a full refund if the asset is not provided.

Categories may have additional category-specific rules. You agree to follow the rules disclosed at listing creation for the category in which you publish.

6.4 Seller representations

For each listing, you represent and warrant that: (a) you own the listed asset or are authorized to sell it; (b) the listing does not infringe any third-party intellectual property, privacy, contractual, or publicity right; (c) the listing complies with all applicable laws, regulations, sanctions, and platform restrictions; (d) you will deliver what you promised in the listing; and (e) for regulated goods or data, you hold every license, registration, or authorization required to list and sell it.

7. Marketplace Fees, Shipping Charges, Penalties, and Taxes

7.1 Marketplace fees

D6N charges a buyer-side marketplace fee on each listing purchase, added to the item price. D6N separately charges a seller-side marketplace fee on each successful sale, deducted from the seller’s item proceeds. These marketplace fees apply to the item transaction and not to shipping. The buyer-facing fee and final checkout total are shown before purchase; the seller-side fee is reflected in the seller’s proceeds and account records. D6N may update its marketplace fees from time to time with notice.

7.2 Physical Goods shipping charges

Physical Goods orders may include outbound or return shipping charges. The party responsible for a shipping charge and the applicable price are shown in the relevant transaction flow or account record. Shipping prices are separate from the marketplace fees described in Section 7.1.

7.3 No-ship penalties and shipping adjustments

D6N applies a no-ship penalty when a seller cancels a Physical Goods order after a shipping label has been generated or uploaded but before carrier acceptance, or when an order in either label-ready state misses the ship-by deadline. Cancelling before a label is generated or uploaded does not incur this penalty. When the seller initiates cancellation, the applicable penalty is shown before confirmation. The penalty, and any separate shipping charge or credit, may be reflected in the seller’s account and deducted from amounts otherwise payable. A shipping credit does not automatically reverse the no-ship penalty.

7.4 Taxes

Each user is responsible for determining, collecting, reporting, and remitting any tax that applies to its activity on the Service, including income tax, withholding tax, sales / use tax, VAT, GST, hotel / occupancy tax, and digital-services tax. Where D6N is legally required to act as a marketplace facilitator and collect tax on a seller’s behalf (for example, in certain U.S. states), D6N may collect and remit that tax and reflect it in the order; this does not change the seller’s underlying tax obligations and does not constitute tax advice.

8. Order Deadlines and Status

Order status, fulfillment requirements, and applicable deadlines are shown in the Service. D6N may update an order based on timing, fulfillment information, or the eligibility rules in these Terms. These rules include:

For Physical Goods, preparing a label alone does not satisfy the seller’s obligation; the parcel must be accepted by the carrier by the displayed ship-by deadline.
An unshipped Physical Goods order may be cancelled or refunded after the ship-by deadline. The no-ship penalty in Section 7.3 applies only if a shipping label has been generated or uploaded.
A delivered order may complete when its return window expires without an eligible return request.
A return may be denied if the buyer misses the displayed return-shipping deadline.

You acknowledge that D6N may cancel, complete, expire, or refund an order when an applicable deadline or eligibility condition is met, with the consequences described in these Terms.

9. Refunds, Returns, Cancellations

9.1 Physical Goods

Buyers may request a return for any reason within fourteen (14) days after delivery (the “return window”). After an eligible return request, the buyer obtains a return label and separately pays the return shipping price unless seller-funded return coverage applies. D6N may refund the original order payment after timely return shipment is confirmed. A separately purchased return shipping price is not part of the original order refund unless D6N expressly shows otherwise. If the buyer fails to hand the return to the carrier by the return-shipping deadline shown for the order, the order may be treated as completed and no refund is issued.

If a parcel is lost in transit, delivery fails, or the parcel is returned to the seller as undeliverable, D6N will refund the buyer once the carrier confirms the failure.

9.2 Data

Data listings are final sale once the asset has been provisioned to the buyer. A refund is available only where (a) the asset was never delivered, (b) the delivered asset is materially different from what the listing described, or (c) the asset cannot be opened, decrypted, or used for a technical reason solely attributable to the seller. Contact support for data-order issues.

9.3 Deadline-driven and seller-failure refunds

If a seller cancels an unshipped Physical Goods order or misses the ship-by deadline, D6N releases or refunds the buyer’s full order payment and the seller receives no payout. The no-ship penalty applies only when a shipping label has been generated or uploaded, as described in Section 7.3. Any separate shipping charge or credit is handled under Section 7.3 and does not automatically reverse the penalty.

9.4 Chargebacks

Buyers agree to use the return, refund, or order-support process in Section 12 before initiating a chargeback. Unjustified chargebacks may result in account suspension. Where a buyer initiates a chargeback, D6N may participate in or contest the chargeback on the seller’s behalf and may reverse the affected order credits or debit the disputed amount from the seller’s balance.

10. Prohibited Listings and Acceptable Use

You may not list, sell, or solicit through the Service any of the following:

Anything illegal in the buyer’s or seller’s jurisdiction;
Weapons, firearms, ammunition, explosives, regulated chemicals, or items designed to cause physical harm;
Controlled substances, prescription medications, or drug paraphernalia;
Counterfeit, stolen, or pirated goods, or anything that infringes a third-party intellectual property, trade-secret, or publicity right;
Datasets containing personally identifiable information collected without a lawful basis, or any data scraped in violation of source-platform terms or applicable law;
Child sexual abuse material or any content that sexualizes minors;
Hate-targeted content, incitement to violence, terrorist propaganda or recruitment material;
Malware, exploits, ransomware, credential dumps, illicit-access services, fraud kits, or services designed to compromise systems or accounts;
Live animals, human remains, organs, blood, or other body parts;
Securities, investment contracts, currency, or any other instrument whose sale is regulated and not authorized through D6N;
Multi-level marketing schemes, lotteries, or other prohibited promotions;
Services that impersonate a real person without their authority, or that exist to facilitate fraud, doxxing, harassment, or election manipulation;
Sexually explicit material, escort or sexual services, and any sexual contact, in any category;
Anything D6N flags as creating an unreasonable risk to buyers, the platform, payment partners, or third parties.

In addition, you agree not to: (a) scrape, crawl, or harvest the Service except through authorized means; (b) reverse-engineer the Service or its automated systems; (c) probe, attack, or attempt to bypass the Service’s security, authentication, rate-limiting, or moderation controls; (d) manipulate the Service’s listing, order, or enforcement systems; (e) use the Service to send spam, unsolicited bulk communications, or to operate a botnet; or (f) infringe the rights of, defraud, or harass any other user.

11. Moderation and Reporting

D6N may, but is not obligated to, review listings, orders, communications, and other activity on the Service. We may, at any time and without prior notice: remove or restrict any listing; cancel any order; freeze payouts; suspend or terminate any account; report unlawful activity to law enforcement; and disclose information as required by law. Report problematic listings or activity to support@d6n.ai.

12. Order Support, Returns, and Chargebacks

12.1 First, talk to the seller (or the buyer)

You agree to attempt to resolve order-level issues, such as delivery, item condition, or a mismatch with the listing, directly through the messaging channel D6N provides on the order before escalating to D6N support or to a payment-network chargeback.

12.2 Returns and order support

Physical Goods use the return process in Section 9.1. Data purchases are final once provided and are not refundable except as stated in Section 9.2. For other order issues, D6N may review support information from either party and apply the refund, cancellation, and chargeback rules in these Terms.

12.3 D6N’s role

D6N is a marketplace operator and not a party to the underlying transaction between the buyer and the seller. D6N’s order-support actions settle the marketplace flow only; they do not constitute legal adjudication, and they do not preclude either party from pursuing other lawful remedies, subject to Section 16.

13. Intellectual Property

13.1 D6N IP

The Service, including its software, interfaces, documentation, automated systems, website, design, and other materials produced by D6N, is owned by Neosphere Inc. or its licensors and is protected by intellectual property and other applicable laws. Nothing in these Terms grants you any right in D6N’s intellectual property except the limited right to use the Service as described.

13.2 Your content; license to D6N

You retain ownership of the content you submit to the Service, including listing copy, descriptions, photos, files, and any data uploaded as part of a Data listing (“Your Content”). You grant D6N a non-exclusive, worldwide, royalty-free, sublicensable license to host, store, reproduce, transform, transcode, index, embed, display, distribute, and otherwise use Your Content to operate, maintain, market, secure, and improve the Service, fulfill orders, and enforce these Terms. For published listings, this license is irrevocable for the period the listing is published and survives termination to the extent necessary to honor existing orders, comply with law, and maintain archival records.

13.3 DMCA / IP infringement

D6N respects intellectual property rights and operates a notice-and-takedown process under the Digital Millennium Copyright Act and analogous laws. To submit a notice, send to support@d6n.ai a written communication that includes: (i) identification of the work claimed to have been infringed; (ii) identification of the allegedly infringing listing or material, with enough detail to locate it; (iii) your contact information; (iv) a statement that you have a good-faith belief that the use is not authorized; (v) a statement, under penalty of perjury, that the information is accurate and you are authorized to act; and (vi) a physical or electronic signature.

14. Privacy

D6N’s collection and use of personal information is governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Service you acknowledge that data necessary to complete a transaction, such as shipping address for Physical Goods, will be shared with the relevant counterparty.

15. Suspension and Termination

D6N may suspend or terminate your access to the Service, any account, any listing, or any order, at any time, with or without notice, if we believe you have violated these Terms, applicable law, a payment provider’s rules, or that your activity creates a risk to the Service, its users, service providers, or third parties. You may stop using the Service and close your account at any time by contacting support@d6n.ai; closure will not extinguish obligations on open orders, pending refunds, taxes, fees, indemnities, or other amounts owed.

On termination, your right to use the Service ends. Sections that by their nature should survive (including without limitation Sections 5.2, 6.4, 7, 9, 13, 14, 17, 18, 19, 20, 21, and 22) survive termination.

16. Marketplace Disclaimer (Important)

D6N is a marketplace and not a manufacturer, distributor, or retailer of goods listed by sellers, an importer of record, common carrier, broker, fiduciary, licensed financial institution, licensed insurer, or registered investment adviser. D6N does not certify or guarantee any listed good or data asset. The seller is the counterparty in each listed-item transaction and bears the obligations associated with the listed item.

17. Disclaimers

THE SERVICE AND ALL LISTINGS, AUTOMATED OUTPUTS, DATA, RECOMMENDATIONS, AND SEARCH RESULTS PROVIDED THROUGH IT ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. D6N DOES NOT WARRANT THE ACCURACY, COMPLETENESS, LEGALITY, OR FITNESS FOR PURPOSE OF ANY LISTING, SELLER REPRESENTATION, OR AUTOMATED OUTPUT.

Where applicable law does not allow exclusion of certain implied warranties, the duration of any such warranty is limited to the minimum period permitted by law.

18. Indemnification

You will defend, indemnify, and hold harmless Neosphere Inc., its affiliates, and its and their officers, directors, employees, contractors, and agents from and against any claim, demand, loss, liability, damage, cost, or expense (including reasonable attorneys’ fees) arising out of or relating to: (a) your use of the Service; (b) any listing you publish; (c) any order you place or fulfill; (d) any act or omission of an AI agent you authorized; (e) your breach of these Terms or of any applicable law; or (f) any infringement or violation of any third-party right by you or Your Content.

19. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER D6N NOR NEOSPHERE INC. NOR ITS LICENSORS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, USE, OR DATA, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE FULLEST EXTENT PERMITTED BY LAW, D6N’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS (US$100) OR (B) THE TOTAL PLATFORM FEES PAID BY YOU TO D6N IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

Nothing in these Terms limits liability that cannot be limited under applicable law (for example, for fraud, gross negligence, willful misconduct, or death or personal injury caused by negligence).

20. Dispute Resolution; Arbitration; Class-Action Waiver

20.1 Informal resolution

Before filing any formal legal claim, you agree to first contact us at support@d6n.ai and to attempt to resolve the dispute informally for at least thirty (30) days.

20.2 Binding individual arbitration

If informal resolution fails, you and D6N agree that any dispute, claim, or controversy arising out of or relating to the Service or these Terms will be resolved by binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules and Procedures then in effect. The seat of arbitration will be Wilmington, Delaware; the language of arbitration will be English. The arbitrator’s award will be final and binding and may be entered as a judgment in any court of competent jurisdiction.

20.3 Class-action and jury-trial waiver

YOU AND D6N AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. YOU AND D6N EACH WAIVE THE RIGHT TO A TRIAL BY JURY.

20.4 Opt-out

You may opt out of this arbitration agreement by sending written notice to support@d6n.ai within thirty (30) days of first accepting these Terms, stating your name, account email, and that you opt out.

20.5 Small claims

Either party may instead bring an individual action in small-claims court for any dispute within that court’s jurisdictional limits.

21. Governing Law

These Terms are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict-of-laws principles. Subject to Section 20, you consent to the exclusive personal jurisdiction and venue of the state and federal courts located in New Castle County, Delaware. If you are a consumer in the European Economic Area, the United Kingdom, or another jurisdiction whose mandatory consumer-protection laws apply, nothing in these Terms deprives you of the protections those laws provide.

22. Changes to These Terms

We may update these Terms from time to time. Updates take effect when posted; we will update the “Last updated” date above and, for material changes, will give at least thirty (30) days’ notice via the Service or by email where required by law. Your continued use of the Service after a change becomes effective constitutes acceptance.

23. Notices and Contact

You consent to receive electronic communications from D6N, and you agree that those communications satisfy any legal requirement that such communications be in writing. Notices to D6N must be sent to:

Neosphere Inc. · D6N

Contact: support@d6n.ai

Web: d6n.ai

24. Miscellaneous

These Terms (together with the Privacy Policy and any category-specific addenda referenced at listing) are the entire agreement between you and D6N regarding the Service and supersede all prior agreements on the same subject.
If any provision is held invalid or unenforceable, the remainder remains in full force, and the invalid provision will be reformed only to the minimum extent necessary.
Failure to enforce a provision is not a waiver of it.
D6N may assign these Terms in whole or in part, including in connection with a merger, acquisition, financing, or sale of assets. You may not assign these Terms without D6N’s prior written consent.
Neither party is liable for any failure or delay caused by events beyond its reasonable control, including acts of God, war, terrorism, civil unrest, pandemic, government action, network or payment-rail outage, or carrier failure.
Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and D6N.
