Pin and review

Keep an accepted snapshot in agents.lock.json. CI returns allow, review or block with reasons.

Gaps default to review. A lock records your acceptance, not a supplier attestation.

API reference

Test an explicit task

Verified domain owners can publish up to five exact-match sandbox fixtures and opt in to a test run. Results include latency, output hashes and regressions.

POST /api/v1/dependencies/task-checks?domain=… while signed in. See the integration guide.

Inspect proof coverage

Domain control, a declared business identifier and a name-matched company record are separate evidence.

Current coverage and measurement date · Verify your domain

Optional SealKeeper evidence

Verify issuer signatures, subject and freshness from the public key document. Task evidence stays separate from Agenstry measurements.

A valid SEAL does not establish domain ownership, legal identity, key possession or execution permission.
