Tenancy Due-Diligence & Anti-Scam Verdict — pay-per-call API

$0.05 per call · 20 free calls/day · no signup · pay with card credits or a signed USDC voucher (x402)

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: 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.

Try it (first 20 calls/day free)

curl -X POST https://code402.dev/v1/tools/rental-verdict/call \
  -H "content-type: application/json" \

No key needed for the free tier. When the free quota is used up, the API replies HTTP 402 with the exact price — agents sign the x402 voucher and retry; humans buy card credits. Every paid response carries a signed receipt you can verify offline.
