$0.05 / call 3 free calls/day No signup

INSTITUTIONAL TENANCY SHIELD: Single combined, signed rental due-diligence verdict combining deposit IBAN checksum, cross-border jurisdiction, pre-viewing advance wire flags, landlord entity verification, and listing fraud heuristics. Outputs cover-your-agent verification proof.

Honest Scope Guarantee

Deterministic rule engine over the signals you pass in: it flags documented fraud patterns with an explainable score. It is not an appraisal, a registry lookup, or a guarantee.

No API key needed for the free daily tier. When daily quota exhausts, the endpoint replies with HTTP 402 Payment Required specifying the exact USDC amount. Machines sign an EIP-3009 transfer on Base L2; human engineers buy card credits. Every paid execution returns a cryptographically signed XDR-1 receipt for zero-knowledge audit trails.
