ambr_verify_hash
Read-onlyIdempotent
Verify a contract's SHA-256 hash to confirm document integrity.
Checks whether the provided hash matches a contract stored on Ambr. Returns verification status, contract metadata, and Reader Portal URL if found.
Args:
hash (string, required): SHA-256 hash (64-character hex string)
Returns:
verified: boolean
contract_id: string (if found)
status: string (if found)
reader_url: string (if found)
Legibility: verification is the point at which legibility becomes provable — matching hash means the prose a human reads and the JSON a machine parses are the same document that was originally signed.
