Api Endpoint

verifier.quantumshieldlabs.dev

Classify a caller-supplied operation claim against caller-supplied evidence under deterministic rules and return a machine-readable handoff receipt. Use this when an orchestrator needs a consistent completion state before accepting an agent's work. VERIFIED_COMPLETE means the submitted evidence supports the submitted claim; QSL does not independently observe the underlying real-world action.
