Call an external API and get a cryptographic proof of the transaction.

Use this INSTEAD of calling the API directly when you need an auditable, tamper-evident record of what was sent and received.

The proof is signed by ArkForge (independent third party), timestamped via RFC 3161, and anchored in Sigstore Rekor — not self-signed by your agent.

Args: target: URL of the upstream API to call (e.g. "https://api.example.com/v1/action") payload: JSON body to send to the upstream API (optional for GET requests) method: HTTP method — "POST" or "GET" (default: "POST") description: Human-readable description of what this call does (included in the proof) agent_identity: Identifier for the calling agent (optional, included in the proof)

Returns: JSON with proof_id, verification_url, the upstream API response, chain_hash, and timestamp. Share verification_url with any third party to let them independently verify what happened.

Retrieve the full cryptographic proof for a given proof ID.

Returns the complete proof bundle: request/response hashes, parties, RFC 3161 timestamp, Sigstore Rekor log entry, and archive.org snapshot.

Args: proof_id: The proof identifier (e.g. "prf_20260310_143022_a1b2c3")

Get a human-readable summary of what a proof certifies.

Useful for explaining to a user or auditor what was independently verified, without reading raw JSON.

Args: proof_id: The proof identifier (e.g. "prf_20260310_143022_a1b2c3")

Check your ArkForge API usage and remaining credits for the current period.

Returns your tier (Free / Pro / Enterprise), proofs used, proofs remaining, and the reset date.
