Virtual Keys & Hard Budgets

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

Creating a key​

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

When creating a key, you can set:

  • Key Name: a label to identify the key in the portal and traces.
  • Budget: an optional hard spend cap (max_budget in USD). There is no day/month/lifetime period picker today — it's a single flat cap.

Keys are stored securely — plaintext is returned exactly once at creation. Portal-issued keys start with sk-antix-….

note

Per-key model allow-lists and per-key rate limits (rpm/tpm) are not yet exposed in the portal's key-creation flow. See Error Handling for the gateway's current (global, not per-key) rate limiting.

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.
