Headers

API-Versionstring required

Example:2025-09-29

ACP API version in YYYY-MM-DD form. If the version is unsupported the endpoint returns an ACP-shaped error carrying supported_versions so the agent can negotiate.

Idempotency-Keystring required

Example:a1b2c3d4-0000-4000-8000-000000000000

Client-generated unique key that makes a write idempotent: a retry carrying the same key returns the original result instead of creating a duplicate. Required on ACP write operations.
