Terms of Service

ProxyStacks Relay ("Relay", "we", "us", or "our") is an independent multi-model AI API gateway operated by an individual developer. Relay provides OpenAI-compatible and related API surfaces, prepaid service balance for metered usage, API key management, usage records, rate limits, and developer workflow tools.

Relay routes approved inference workloads through backend capacity that we procure from paid commercial cloud and AI API channels available to individual developers (including, without limitation, services such as Qiniu Cloud, commercial API routing platforms, and Tencent Cloud TokenHub-related channels). Relay is not affiliated with, endorsed by, sponsored by, owned by, or operated by OpenAI, Anthropic, Google, Tencent Cloud, or any other foundation model vendor unless such relationship is separately established in writing.

Unless separately stated in a written agreement, Relay is not an official reseller, distributor, agent, or authorized representative of any upstream model vendor.

Customers purchase access to Relay's gateway software and service balance used for metering token usage within Relay. Customers do not receive upstream provider accounts, upstream API keys, official reseller rights, sublicensing rights, or any right to represent themselves as customers, partners, or authorized users of an upstream vendor through Relay.

• You must be legally able to enter into a binding agreement and provide accurate account information.
• You are responsible for activity under your account and for keeping API keys and login access secure.
• You must promptly revoke a key and contact us if you believe your account or a key has been compromised.
• You may not share, resell, or transfer your account or Relay API access unless we have agreed to it in writing.

Relay uses prepaid balance. Each successful top-up adds the stated amount of service balance to your Relay balance. API calls deduct balance according to the published model rates and the measured token usage for each request.

• Unused balance roll over while your account remains available; balance have no cash value and cannot be transferred.
• Balance are digital service balance for use within Relay only. They are not stored value, currency, gift cards, or financial instruments.
• Consumed balance are generally non-refundable except where required by law or expressly stated in our Refund Policy.
• We may delay, limit, or refuse high-risk usage where needed to prevent abuse, unpaid provider costs, fraud, or chargeback exposure.
• Requests pause when your available balance is insufficient for the estimated cost of a call.
• Model availability and token rates can change. Current rates are shown on the pricing page or in the product before use.

Relay may route AI workload requests to cloud model and API services that are lawfully available to us through paid accounts or commercial usage channels. Provider availability, supported models, model names, features, pricing, rate limits, safety filters, regional availability, and technical behavior may change without notice.

Use of Relay does not create a direct contractual relationship between you and any upstream provider. You must not use Relay to bypass an upstream provider's terms, safety systems, geographic restrictions, content moderation, access controls, account requirements, or rate limits.

We may suspend, remove, restrict, or replace any provider, model, route, feature, account, key, or workload where required by provider requirements, law, security concerns, abuse prevention, payment risk, or operational risk.
