For teams using external agents and MCP servers: inspect measured evidence, watch changes, and keep a record of what your team accepted. Unknown evidence stays explicit.
Have a client configuration? Extract and check its public endpoints locally. Maintaining integrations for clients? Explore the agency pilot.

}Keep an accepted snapshot in agents.lock.json. CI compares it with current evidence and returns allow, review or block with reasons, before/after data and policy hashes.
Default gaps require review. Configure stricter handling explicitly. A lock records your acceptance; it is not a supplier attestation.
API referenceVerified domain owners can publish up to five exact-match sandbox fixtures and opt in to a test run. Results include fixture version, latency, output hashes and comparable regressions. Cost remains unknown when unobserved.
Run with POST /api/v1/dependencies/task-checks?domain=… while signed in. Read the schema and example in the integration guide.
Domain control, a declared business identifier and an active name-matched company record are separate evidence. Zero verified records means zero recorded proof.
Current coverage and measurement date · Verify your domainVerify issuer signatures, subject and credential freshness using the public key document. Keep its task evidence categories separate from Agenstry measurements.
A valid SEAL does not establish domain ownership, legal identity, key possession or execution permission.
