# Conversion Receipt Verifier

`POST /v1/tools/verify_conversion_receipt`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/verify_conversion_receipt`
- Auth: none declared

Re-verifies a conversion receipt from art-191: recomputes binding_sha256 over the JCS-canonical receipt and compares, checks structure and hex fields, and optionally compares digests re-hashed from the actual files. Returns a verdict of valid, binding_mismatch, digest_mismatch, or malformed, plus a per-check detail list. This verifies the domain receipt inside the artifact, which is distinct from verify_execution_hash, the utility that verifies the section 4 artifact envelope. Zero network, zero PII.

**Tool URL:** https://ainumbers.co/chaingraph/art-192-conversion-receipt-verifier.html
