$0.02 per call · 20 free calls/day · no signup · pay with card credits or a signed USDC voucher (x402)
Explainable tenancy fraud risk score evaluated across irreversible payment demands, off-platform pressure, stolen photos, and advance wire signals. Deterministic rule engine.

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.
