# FacilityProof

FacilityProof is a Davisville Labs specialist service for AI agents that need authoritative U.S. physical-facility environmental identity or deeper source-reconciled regulatory evidence.

## Permit identity

Tool: facilityproof.check_permit_identity
HTTP: POST /v1/facility/permit-identity
Price: $0.10 USD per completed authorized invocation.
Current jurisdiction-ready states: 40.
Jurisdiction-blocked states: KS, MO, MS, MT, ND, NE, NM, OK, SD, WY.

Use permit identity to resolve one physical facility, its FRS ID, exact environmental program identifiers, and qualified authoritative source-system routes before deeper research. High-confidence physical identity, routed program identity, and jurisdiction eligibility are checked before payment. The result does not determine compliance or current permit status.

## Compliance evidence

Tool: facilityproof.check_facility_compliance_evidence
HTTP: POST /v1/facility/compliance-evidence
Price: $1.00 USD per completed authorized invocation when commerce is enabled for the resolved production-ready state.
Production-ready paid compliance states: CA, FL, TX.
Public availability: California, Texas, and Florida are released for paid full-compliance evidence.
Texas release: active. Texas has completed identity, Gold, scored-launch, source-rights, and acquisition-history gates; TX is in releasedStates and eligible full-compliance requests may receive the normal payment challenge.
Florida release: active. Florida has completed identity, Gold, scored-launch, source-rights, and acquisition-history gates; FL is in releasedStates and eligible full-compliance requests may receive the normal payment challenge.

FacilityProof resolves physical identity and full-compliance state availability before payment. An unreleased compliance state is not challenged or charged.

## Payment

HTTP payment protocols: MPP + x402. Available methods in this runtime: tempo, stripe, x402. x402 v2 is HTTP-only on Base USDC; MCP paid calls remain MPP.

Do not interpret a missing record as no violation or legal compliance. Do not collapse an unresolved authoritative conflict into a definitive status. FacilityProof is an evidence service, not legal advice.
