Terms of Use

1. Your Agreement with Katara

These Terms of Use are between you and Katara Labs, Inc., a Delaware corporation (“Katara,” “we,” or “us”). They cover our websites, Katara Cortex, chat, API and x402 access, and provider participation, collectively the “Services.”

You must clearly accept these terms when registering for an account or before your first paid authorization, including wallet-only x402 access. Acceptance must identify the applicable terms version and is separate from optional marketing or analytics consent. If you are acting for an organization, you must have authority to accept on its behalf; “you” then includes that organization.

The Privacy Policy explains how personal information is handled. A separately signed agreement with Katara controls over these terms for the subject matter it expressly covers.

2. Eligibility and Access

You must be at least 13 years old and meet any higher minimum age required by the law where you live. If you are under 18, a parent or legal guardian must review and accept these terms with you and give permission for your use, including any paid activity. You must also meet any higher age requirement applicable to a selected model or feature.

Provider participation and independent spending authority require an adult with the legal capacity and authority for that activity. If you are under 18, paid use requires a parent or legal guardian’s authorization; an agent cannot supply that authorization for you. Anyone acting for an organization must be authorized to do so.

Use the Services only where permitted by law and comply with applicable sanctions and export restrictions. Katara may restrict access based on legal requirements and supported markets. Available countries and payment routes may change; no availability statement authorizes prohibited use.

Provide accurate account or provider information where requested. Protect your accounts, API credentials, signing keys, wallets, and devices. You are responsible for access you authorize and for promptly reporting a suspected compromise. This does not excuse Katara’s own breach of its obligations or remove rights the law gives you.

Some access paths may use a wallet authorization rather than a conventional account. The applicable access method does not change your obligations under these terms.

3. What Katara Cortex Provides

Katara Cortex connects inference requests with compute providers serving supported models. People can use chat, developers can integrate the API, and agents can pay for inference through x402. Providers supply compute and earn USDC for eligible work under the applicable settlement rules.

Model availability, provider capacity, prices, and supported features may change. Unless a separate agreement expressly says otherwise, there is no promise that a particular provider or model will always be available or that a request will complete within a particular time.

Managed fallback is enabled for supported models and may use multiple third-party providers. Katara may select, add, remove, or replace fallback providers at its discretion at any time, without prior notice except where applicable law or a separate agreement requires otherwise. We do not guarantee a particular provider or a fixed provider list.

Fallback remains subject to the applicable price, model terms, and provider data practices, which may differ in retention, training permissions, and processing location. Changing providers does not waive Katara’s privacy commitments or any required disclosure, consent, or transfer safeguard. See the managed fallback disclosure.

The serving provider receives readable request content, which may include conversation history and tool data. Model or bundle verification does not prove that a provider did not copy that content, or guarantee that an output is factually correct, safe for every purpose, or free of third-party rights.

4. Prices, USDC, and Onchain Settlement

Inference is priced and paid in USDC. The applicable price, metering basis, Katara fee, any minimum charge, and any separate network or transaction charge must be disclosed before you authorize the relevant request or spending arrangement. Example prices on the marketing site are illustrative.

By submitting a paid request or granting a spending authorization, you authorize the charges within the scope of that authorization. Protect and review allowances, budgets, recipients, and supported token/network details before signing. A changed price applies to future authorizations and does not change the agreed price for completed work.

Settlement takes place onchain through the supported payment mechanism. USDC is a digital token; Katara does not issue it or guarantee its market value, redemption, availability, or its issuer’s performance. Use only the token and network identified for the transaction. An unsupported transfer can be unrecoverable.

Public blockchains, wallets, payment facilitators, and smart contracts can experience errors, attacks, congestion, or outages. A confirmed transaction may not be reversible through the protocol. These characteristics do not eliminate a refund, correction, or other remedy that Katara owes under these terms or applicable law.

You are responsible for taxes that legally apply to your purchases or provider earnings, except taxes on Katara’s own income. Any taxes Katara is required to collect will be identified as required by law.

5. Billing Errors, Unused Balances, and Refunds

Contact [email protected] if you believe a charge is duplicated, incorrectly calculated, or relates to inference that was not delivered. Provide the request or transaction identifier and the amount in question; do not send wallet secrets or private inference content. Katara will investigate, correct substantiated duplicate or incorrect charges, and refund paid inference that was not delivered.

Charges for correctly delivered inference are not refundable merely because you dislike an output, except where the law or an expressly applicable written policy provides a refund. This rule does not limit remedies for a defective service, an unauthorized or incorrect charge, or rights that cannot legally be excluded.

We review partial-delivery cases fairly, considering the work actually delivered, the authorization, and the reason for interruption. Any adjustment must preserve applicable consumer remedies.

Unused balances do not expire and are not automatically forfeited. You may withdraw unused funds, subject to pending authorized charges and legal restrictions. The applicable withdrawal process, timing, and any disclosed transaction costs must be explained before funding. Suspension or account closure does not remove this right. Provider payments remain subject to valid work and the applicable payment rules.

6. Applications, Recursive Agents, and Spending Authority

You may build applications and agents that use Katara Cortex, including agents that delegate tasks to additional agents. You remain responsible for the actions and spending you authorize through your integration, including delegated requests. Creating a child agent does not create a new party to this agreement or remove applicable usage limits.

Configure budgets, recursion depth, concurrency, credentials, tool access, and stop conditions appropriate to your workflow. x402 provides a payment mechanism; it does not by itself impose a global budget or guarantee that an agent’s decisions are correct. Each paid inference request can incur a separate charge.

You must provide your own users with appropriate notices and obtain any permissions needed for their data and actions. An agent must not represent that it has authority to spend someone else’s funds or bind another person unless that authority was actually granted.

“Recursive” does not mean unmetered, free, or guaranteed unlimited capacity. You must respect published rate limits and must not evade spending or security restrictions.

7. Your Content and Model Outputs

You retain the rights you already have in the material you submit. Katara does not claim ownership of your prompts, chat messages, code, or resulting outputs. You must have the rights and permissions necessary to submit material and authorize its processing, including personal information belonging to others.

You give Katara permission to process and transmit your content to fulfill your request and return the result. When you use the chat application, you also permit the separate account service to save, display, and synchronize your conversation history and any supported content you choose to save, until it is deleted under the applicable retention process.

For service or security incident investigation, you also permit Katara to capture affected inference content temporarily, subject to applicable law and the incident-capture disclosure. Katara deletes this captured content within seven days. This is a limited exception to ordinary router processing without content retention.

These functional permissions do not authorize Katara to sell your content, use it to train models, or maintain routine router content logs. Account chat history and managed fallback have the separate handling described in the Privacy Policy. Katara has opted out of training on its DeepSeek production API traffic; this is specific to DeepSeek and does not establish a uniform training or retention policy for other fallback providers.

Keep your own copy of results you need. Model licenses and applicable law may limit how content can be used regardless of where it is stored.

Output rights can depend on applicable law and the model’s license. An output may be similar to output received by someone else and may not qualify for exclusive rights. Katara cannot grant rights belonging to a third party. Review the applicable model terms and the output before using or distributing it.

8. Acceptable Use

Use the Services lawfully and respect the rights of others. You must not use the Services to:

• Exploit children, create or distribute child sexual abuse material, facilitate violence, or carry out unlawful abuse or harassment.
• Commit fraud, impersonate someone deceptively, steal funds or credentials, launder money, or evade applicable sanctions.
• Deploy malware, obtain unauthorized access, disrupt infrastructure, or extract another user’s private information.
• Infringe intellectual property or privacy rights, or submit data you lack authority to process.
• Falsify usage, offers, signatures, receipts, model identity, verification results, or settlement information.
• Bypass payment, authorization, rate limits, or security controls, including by distributing prohibited activity across agents or accounts.

Model-specific restrictions also apply when disclosed and applicable to your selected model. Ordinary API automation, application integration, and recursive agent workflows are permitted within these terms. Security research must remain within authorization and must not access other users’ data or disrupt service.

9. Responsibilities of Compute Providers

If you provide compute, you must have authority to operate the hardware and serve the relevant models. Publish accurate offers, run the supported model and bundle you advertise, follow the applicable verification and metering requirements, and submit truthful receipts.

Use inference content only to serve the authorized request. Independent providers must not store prompts or outputs after processing, inspect them beyond what execution requires, or put them in persistent logs. Permitted logs contain operational metadata, such as timing, token counts, and job identifiers, with content excluded from errors. These terms also prohibit disclosing that content for unrelated purposes or using it for training.

Katara’s temporary incident-capture exception does not authorize independent providers to retain their own copies. Protect content while processing it and report a security incident affecting Katara traffic to [email protected] without undue delay and in all cases within 24 hours of discovery. Do not delay the initial report until an investigation is complete. Validation with synthetic traffic does not replace your duty to follow these restrictions.

You are responsible for your infrastructure costs, model-license compliance, earnings taxes, and obligations to your personnel or hosting vendors. Participation does not guarantee request volume, utilization, revenue, or a particular ranking or routing preference.

Provider participation requires recorded acceptance of the content-handling obligations above. A separately accepted provider agreement may set additional technical, security, audit, and payment requirements. Katara may immediately suspend routing to investigate suspected content misuse, misrepresentation, failed verification, or other material violations.

We provide an explanation and an opportunity to respond where doing so would not compromise security or violate law. You may dispute a routing suspension or payment decision through [email protected]. We review relevant records and your response; suspension does not automatically forfeit payment for valid work.

10. AI Limitations and Your Decisions

AI can produce inaccurate facts, insecure code, biased material, or unsuitable instructions. Evaluate outputs before relying on them, executing code, publishing material, or allowing an agent to take an external action.

The Services do not replace a qualified professional or emergency assistance. Do not use an unreviewed output as the sole basis for a decision that can materially affect someone’s health, safety, legal rights, or access to important opportunities. Use only a workflow that meets the laws and safeguards applicable to your activity.

Information about a token, model, provider, or protocol is not a promise of investment returns or a guarantee of performance.

11. Katara Materials and Third-Party Services

Katara and its licensors retain their rights in the Services, website materials, and branding. These terms permit you to use the Services as described; they do not transfer Katara’s trademarks or proprietary technology to you. Software released under an open-source license remains governed by that license.

Models, wallets, tools, and third-party applications can have separate licenses and terms. Those terms govern the corresponding third-party relationship where applicable, but do not remove obligations Katara has under this agreement or mandatory law. An integration or listing is not a guarantee about that third party.

12. Changes, Suspension, and Ending Use

You may stop using the Services at any time and request closure of a Katara account through the contact details below. Stop running agents and revoke relevant credentials or spending authorizations as appropriate; closing a browser window may not stop an independently running agent.

Katara may limit or suspend access when reasonably necessary to address a material violation, nonpayment, a security threat, unlawful activity, or a legal requirement. We will provide an explanation and an opportunity to resolve the issue where reasonably practicable, unless doing so would create a security risk or violate law.

We may change or retire features and will provide reasonable notice of a material discontinuation affecting paid use when practicable. Ending access does not erase valid charges, eliminate a required refund, transfer ownership of your content, or automatically forfeit unused funds.

Terms concerning accrued payments, content rights, lawful liability limits, and dispute resolution continue as needed to resolve matters arising before termination.

13. Service Warranties

Except for an express commitment in these terms, a separate signed agreement, or a warranty required by law, the Services are provided on an “as available” basis. Katara does not warrant uninterrupted operation, a particular output, or fitness for your specific use case.

To the extent legally permitted, implied warranties of merchantability, fitness for a particular purpose, and noninfringement are excluded. This clause does not override an express privacy or payment commitment, excuse fraud, or remove a consumer guarantee that applicable law makes nonwaivable.

14. Limits on Liability

To the extent permitted by applicable law, neither party is liable under these terms for indirect or consequential losses such as lost business opportunities or anticipated profits, where those losses are not recoverable as direct losses under applicable law.

To the maximum extent permitted by applicable law, Katara’s total aggregate liability arising out of or relating to the Services or these terms will not exceed US$100. Multiple claims do not increase this aggregate limit.

The exclusions and cap do not apply to liability that cannot lawfully be excluded or limited. This includes liability for fraud, willful misconduct, gross negligence, or death or personal injury where applicable law prohibits such a limitation. The cap does not reduce an unused balance, valid refund, or billing correction Katara owes you. Your statutory consumer rights remain intact.

15. Governing Law and Disputes

Please first contact Katara with a description of a dispute and the remedy requested so the parties can try to resolve it. This does not prevent urgent relief, a regulator complaint, or filing within a legal deadline.

These terms are governed by Delaware law, excluding its conflict-of-laws rules. Subject to mandatory consumer protections and any right to bring a claim in another forum, disputes may be brought in the state or federal courts located in Delaware, and the parties consent to those courts’ jurisdiction.

These terms do not require arbitration or waive participation in a class proceeding. If the law where you live gives you protections or a right to sue locally that cannot be waived, those rights continue to apply.

16. Updates, General Terms, and Contact

Ordinary material revisions to these terms will be presented at least 30 days before they govern future use, through the relevant service or available account contact channel. A faster change may be required by law or to address an urgent security issue; in those cases, we provide notice as soon as reasonably possible. Revisions carry an updated effective date, and we seek renewed acceptance where required. Revised terms do not retroactively change completed transactions.

If a provision is unenforceable, the remaining terms continue to apply to the extent permitted by law. A failure to enforce a provision once does not waive it for the future. Neither party may transfer this agreement in a way that unlawfully reduces the other party’s rights. A lawful successor to Katara’s business must assume the applicable obligations.
