Core concepts

Tchavi is a secure gateway that gives you access to multiple AI providers through one API key and one credit balance.

Tchavi is a secure gateway (a proxy) that sits between your application and multiple AI providers — OpenAI, Anthropic, Google, and more. Instead of managing a separate account, key, and bill for each provider, you use one Tchavi API key and one credit balance to reach every model.

OpenAI API compatibility

Tchavi is 100% compatible with the OpenAI API format. The request and response shapes are the same, and the response is a transparent pass-through of the provider's format. If you already use the OpenAI SDK or any OpenAI-compatible library, you only change two things: the base URL and the API key — the rest of your code stays the same.

See Base URL for full SDK examples and Authentication for how to pass your key.

Credit-based billing

There is no subscription. Tchavi is pay-as-you-go: each API request consumes credits based on the model used and the number of tokens processed. You start with 500 free credits on signup, and recharge whenever you want — credits never expire into a monthly plan.

Every API response carries metadata headers so you can track usage in real time:

  • X-Credits-Used — credits consumed by this request
  • X-Credits-Remaining — your current credit balance
  • X-RateLimit-RPM-Limit / X-RateLimit-RPM-Remaining — your requests-per-minute budget
  • X-RateLimit-TPM-Limit / X-RateLimit-TPM-Remaining — your tokens-per-minute budget
  • X-Request-Id — unique request ID for support and debugging

See Credits & Billing for how credits are calculated.

Account levels

Rate limits depend on your account level, which is unlocked automatically based on your lifetime spend on the platform — there is no plan to choose. The levels are Free, Builder, Growth, and Pro, each raising your requests-per-minute (RPM) and tokens-per-minute (TPM) budgets and the number of API keys you can create.

See Rate Limits for the full table.
