  description: >-
    The ai-coustics SDK authenticates with a license (SDK) key on trusted
    servers, or with short-lived JWTs minted from your backend for untrusted
    clients. JWTs are issued by a token-minting endpoint protected with HTTP
    Basic auth using the SDK api_key as the username and an empty password.
schemes:
  - name: sdkLicenseKey
    type: apiKey
    in: sdk-config
    description: >-
      Self-service SDK license key generated in the developer platform
      (developers.ai-coustics.com). Credential format is `<payload>.<signature>`
      where the payload is base64-encoded JSON with fields user, version and
      api_key. Embed directly in trusted server environments.

  - name: jwtBearer
    type: http
    scheme: bearer
    bearerFormat: JWT
    description: >-
      Short-lived JWT dropped in exactly where a license key would be used, for
      untrusted client-side apps. Carries an `exp` claim (Unix seconds), ~1 hour
      TTL. Refresh proactively via the processor's update_bearer_token() without
      recreating the processor or reloading the model.
  - name: tokenMintBasicAuth
    type: http
    scheme: basic
    description: >-
      HTTP Basic auth used to call the token-minting endpoint. The SDK api_key is
      the username; the password is empty.
    token_endpoint: https://api.ai-coustics.io/v1/sdk/tokens
    response_fields: [token, expires_at]
notes:
  - The legacy REST API (api-key based, single call voice enhancement) was sunset in 2026; migrate to the SDK.
  - Offline entitlements in JWT licenses were added in SDK 0.21.1 (2026-06-26).
