summary:
  types: [apiKey]
  api_key_in: [header]
  signing: ed25519
  note: >-
    CoinSwitch PRO uses an API key + Ed25519 secret-key request-signing scheme
    (not OAuth). Every authenticated request is signed and carries three headers.
schemes:
  - name: CoinSwitchApiKey
    type: apiKey

    key_header: X-AUTH-APIKEY
    description: >-
      Hex-encoded API key issued from the CoinSwitch PRO account. Sent on every
      authenticated request in the X-AUTH-APIKEY header.

    signed_message: "METHOD + path + epoch"
    description: >-
      The client builds signed_message = HTTP_METHOD + url-decoded-path(+query) +
      epoch, signs it with the account's Ed25519 secret key, and sends the hex
      signature in X-AUTH-SIGNATURE. X-AUTH-EPOCH is the current Unix millisecond
      timestamp as a string. The X-AUTH-EPOCH timestamp component was introduced
      as a security upgrade on 2 Jul 2024; the legacy scheme was phased out after
      15 Aug 2024.

headers:
  - X-AUTH-APIKEY
  - X-AUTH-SIGNATURE
  - X-AUTH-EPOCH
notes: >-
  No OAuth2/OIDC surface — key-auth provider, so no scopes/ artifact. Reference
  signing implementations are published for Python, Java, Go, and Node.js.
