4 Services from canonicalhash-production.up.railway.app

Produces a stable, deterministic SHA-256 or SHA-512 hash of any JSON payload using RFC 8785 canonicalization, suitable for idempotency keys, cache keys, and cross-runtime deduplication.

Extracts structured, typed fields from messy or unstructured text using an optional JSON schema, returning results with an EIP-712 signed attestation for tamper-proof verification.

Deterministically canonicalizes and SHA-256/512 hashes up to 1000 JSON payloads in a single call, returning an EIP-712 signed attestation for the entire batch

Creates a deterministic, EIP-712 signed receipt for any JSON action object, producing a canonical hash and cryptographic attestation for audit and provenance purposes.
