Token usage, request volume, balance, orders, recharges, refunds, and billing records;

Rate limiting, concurrency control, anomaly monitoring, content security, and account security protection;

Management backend, announcements, tickets, notifications, customer support, and other operational functions.

This Service only provides GPT/Claude APIs and does not provide APIs for other models. Specific functions are subject to the pages, interfaces, announcements, and configurations actually provided by NextHub. We may add, adjust, suspend, or remove functions based on operational, security, compliance, upstream service changes, or technical maintenance needs.

2. Account and Eligibility You must have full civil capacity and capability to enter into and perform these Terms. If you are using this Service on behalf of an enterprise, organization, or other entity, you confirm that you have the authority to bind that entity to these Terms.

You should provide true, accurate, complete, and up-to-date registration, authentication, payment, and contact information, and update it promptly after any changes. Losses, notification failures, service interruptions, or disputes arising from inaccurate, incomplete, or untimely updated information shall be borne by you.

You must properly safeguard your account, password, two-factor authentication credentials, API Keys, access tokens, and other security credentials. All operations and requests made using your account or API Key are deemed to be your actions, unless you can prove that such actions were not caused by your fault, authorization, or improper management.

Without our express written consent, you may not transfer, sell, rent, share, or lend your account or API Key, nor obtain or use accounts through batch registration, automated registration, credential stuffing, or bypassing login verification.

3. API Key and Call Responsibility You should only use API Keys generated by NextHub for lawful, compliant, and authorized business purposes. You are responsible for all requests, input content, generated results, downstream applications, end-user behavior, and resulting fees, risks, complaints, claims, and liabilities arising from your account or API Key.

You must not expose API Keys publicly, nor write API Keys into frontend public code, public repositories, client logs, webpage source code, or other uncontrolled environments. If you discover API Key leakage, abnormal calls, or theft, you should immediately disable, reset, or delete the relevant Key on the platform and contact us promptly.

We may take measures such as rate limiting, suspension, disabling, deletion, re-authentication, or requesting supplementary materials for API Keys based on security, compliance, billing, rate limits, upstream requirements, or abnormal behavior monitoring results.

4. Fees, Balance, and Metering This Service may charge based on request volume, token count, Claude model type, service tier, account pool resources, packages, concurrency capacity, recharge balance, or other billing methods. Specific prices, discounts, packages, granted credits, settlement metrics, and deduction rules are subject to NextHub pages, orders, announcements, or separate agreements between the parties.

You understand and agree that:

Billing statistics may be affected by upstream returns, GPT/Claude metering standards, network retries, streaming responses, caching, failed requests, system latency, and other factors;

Real-time usage displayed on the platform may have a slight delay; final determinations shall be based on platform backend records, order records, and settlement records;

Granted credits, test credits, coupons, discounts, promotional balances, etc., may have expiration dates, scope of use, and restrictions such as being non-withdrawable and non-transferable;

Fees arising from your configuration errors, key leakage, downstream abuse, excessive calls, or failure to set reasonable limits shall be borne by you.

5. Recharges, Refunds, and Invoices This Service may support Alipay, WeChat Pay, Stripe, Airwallex, Crypto, or other payment methods. Payment channels, crediting times, handling fees, currencies, taxes, refund capabilities, and invoice capabilities are subject to NextHub's actual activation status and payment service provider rules.

Except as otherwise required by applicable laws and regulations, expressly promised on the order page, or confirmed by us as a systemic billing error, consumed credits, used services, already-issued and effective virtual balances, granted credits, promotional benefits, customized services, manual services, and orders for which upstream costs have already been incurred are generally not eligible for refunds.

If you believe an order, deduction, or usage is abnormal, you should submit the order number, call time, API Key identifier, request ID, billing screenshots, and other necessary materials as soon as possible after discovery. We will conduct an investigation based on platform logs, payment records, upstream returns, and risk control records.

6. User Content and Generated Results The prompts, context, files, code, images, metadata, system instructions, and other inputs you submit through this Service, as well as the text, code, structured data, or other outputs returned by GPT/Claude, are collectively referred to as "Content."

You warrant that you have the necessary rights, authorizations, and legal basis for the Content submitted to this Service, and ensure that the Content does not violate laws and regulations, third-party rights, OpenAI/Anthropic terms, platform policies, or these Terms.

GPT/Claude outputs are probabilistic and uncertain, and may contain errors, omissions, biases, outdated information, incompleteness, unavailability, unsuitability for your scenario, or inconsistencies with facts. You should not rely on outputs as the sole basis for factual, legal, medical, financial, investment, security, compliance, or other professional judgments.
