Authorizations

​
Authorization
string
header
required

API key issued at onboarding. Passed as a Bearer token in the Authorization header: Authorization: Bearer <api-key>. Identifies the caller and determines organization scope. Invalid or revoked keys return 401 with error type authentication_error.

​
X-Signature
string
header
required

Ed25519 or RSA-SHA256 asymmetric signature over the request payload (ADR-0015). Provides request integrity and non-repudiation. The signature covers the HTTP method, path, query string, request body, and timestamp. Invalid signatures return 401 with error type authentication_error.

​
X-Timestamp
string
header
required

Unix timestamp (seconds) of when the request was signed. Server rejects requests where the timestamp drifts beyond +/-60 seconds from server time to prevent replay attacks. Must match the timestamp used in the signature computation.
