  note: >-
    ADVANCE.AI uses a signed key-exchange followed by a bearer-style header token. There is no OAuth
    2.0, no OpenID Connect and no documented mTLS, so there is no scope surface — see the absence of
    scopes/ in this repo, which is correct rather than missing.
schemes:
- name: AccessToken
  type: apiKey
  in: header
  parameter: X-ACCESS-TOKEN
  description: >-
    Short-lived access token obtained from POST /openapi/auth/ticket/v1/generate-token and passed on
    every other operation. One token is valid across all ADVANCE.AI Open APIs and is reusable until
    it expires. Requesting a new token does NOT invalidate an outstanding one.
  sources:

  - https://doc.advance.ai/liveness_detection.html
credentials:
  issued_via: >-
    accessKey and secretKey are issued per account and read from the ADVANCE.AI Websaas platform
    under Account > Account Management. There is no self-service key issuance — access is sales-led
    via https://advance.ai/book-free-demo/.
  key_pair:
  - name: accessKey
    role: public identifier, sent in the token request body
  - name: secretKey
    role: shared secret, never transmitted; used only to compute the signature

    description: SHA256 hex digest of the concatenation accessKey + secretKey + timestamp.
  - name: timestamp
    required: true
    description: >-
      13-digit epoch milliseconds. Must be the same value used inside the signature. ADVANCE.AI
      suggests staying within 300 seconds of current time; a stale value returns
      PARAMETER_ERROR "Timestamp error".

failure_modes:
- code: PARAMETER_ERROR
  meaning: Missing field, "Timestamp error", or "Signature error".
  billed: false
- code: ACCOUNT_DISABLED
  meaning: Account Disabled — contact the ADVANCE.AI sales manager.
  billed: false
- code: IAM_FAILED
  meaning: >-
    Returned by the business operations rather than the token endpoint. Covers "Token not found or
    expired", "Access Key not found or expired", "Account not authorized for this country",
    "Account not authorized for this domain", "Account is expired" and "Account is disabled".
  billed: false
notes:
- >-
  The HTTP status is 200 even for authentication failure. Clients must branch on the envelope `code`
  field, never on the HTTP status.
- >-
  ADVANCE.AI explicitly advises re-obtaining a token when the previous one expires, and states the
  token is shared across every Open API, so one token cache serves the whole integration.
