note: >-
  The published OpenAPI documents declare NO components.securitySchemes and apply no
  security[] requirement, so the mechanical derive pass (derive-authentication.py)
  returned an empty profile. This profile is therefore captured from the provider's
  documentation, which describes the scheme in full. Documenting the scheme in the
  spec is the single highest-value contract fix available to Copper.

  oauth2_flows: []
  signed_requests: true
schemes:
- name: ApiKeyAuth
  type: apiKey
  in: header
  parameter_name: Authorization
  value_format: ApiKey {API_KEY}
  description: >-
    API key issued in the Copper Platform UI under Settings > API Keys. Keys may be
    owned by a user account or, recommended for integrations, by a service account so
    the key survives team changes. Keys can be restricted to an IP allowlist.

- name: RequestSignature
  type: httpSignature
  in: header
  parameter_name: X-Signature
  algorithm: HMAC-SHA256

  description: >-
    Per-request integrity signature. Every request must additionally carry X-Signature
    and X-Timestamp.
  sources:
  - https://developer.copper.co/api-reference/authentication
required_headers:
- header: Authorization
  description: API key obtained on the Copper Platform, in the form "ApiKey {API_KEY}".
- header: X-Signature
  description: Hex-encoded HMAC-SHA256 signature of the request.
- header: X-Timestamp
  description: Request timestamp as a UNIX timestamp in milliseconds.
- header: Content-Type
  description: application/json
signature:
  algorithm: HMAC-SHA256
  encoding: hex
  secret: API Secret issued alongside the API key
  string_to_sign: '{X-Timestamp}{HTTP_METHOD_UPPERCASE}{path_including_/platform_prefix_and_query}{request_body}'
  notes:
  - Timestamp is milliseconds since the Unix epoch, not seconds.
  - HTTP method must be uppercase.
  - Path must include the /platform prefix and all query parameters, e.g. /platform/orders?limit=1000.
  - Use an empty string for the body when the request has no body.

  - bash
  - python

service_accounts:
  docs: https://developer.copper.co/api-reference/service-accounts
  description: >-
    Recommended owner for integration API keys. Permissions are granted per service
    account and per portfolio.
  permission_types:
  - Trader
  - Withdrawal Operator
  - Loan Manager
  - Approver
ip_allowlist:
  supported: true
  description: An API key may be restricted to a set of source IP addresses.
oauth2: false
scopes_artifact: null
scopes_note: >-
  Copper uses API-key + HMAC signature authentication with role-based service-account
  permissions. There is no OAuth 2.0 surface and therefore no scope reference, so no
  scopes/ artifact is emitted.
