On ATP

The same governance applies to every model on the gateway:

  • Project API key — spend and revocation bound to one project
  • Model allowlist — only enabled models may be called
  • Credits — 1 USD = 100 credits, debited per completed request
  • Per-request logs — model, key, project, credits for audit

Cost estimator

A list-price estimate for a month of traffic. Actual spend follows each completed request.

List-price estimate (1 USD = 100 credits); actual cost comes from each request's response. Prompt-cache hits bill input at the lower cache-read rate, so real spend can be lower.
