Virtual Keys, Rate Limits & Hard Budgets

Never distribute raw provider keys. Antix issues Virtual Keys that act as middleware interceptors, atomically validating budgets and rate limits before routing traffic upstream.

Creating a key​

Keys can be generated directly from the Antix portal dashboard at https://antix.antigma.ai/portal.

When creating a key, you can configure:

  • Models: Restrict which models the key can access.
  • Budget: Hard spend cap (max_budget) per day, month, or lifetime.
  • Rate Limits: Maximum requests or tokens per minute.

Keys are stored securely — plaintext is returned exactly once at creation.

Reliable Billing​

Antix strictly enforces budgets to prevent overruns. Costs are estimated and reserved before any request goes upstream. If a request would exceed the key's max_budget, it is instantly rejected with a 402 Payment Required error.

Once a request completes or is cancelled, costs are accurately reconciled. This strict enforcement eliminates double-spending and ensures that your budget caps are strictly adhered to, even under heavy concurrent load.
