get_receiptread-only
FREE — fetch the public receipt for an attestation: content hash, model, timestamps, Ed25519 signature, and Merkle anchor proof. Raw prompt/response are never stored, so receipts contain proof material only. No wallet needed.
notarize_batch
Notarize up to 20 AI inferences in one call — one signed attestation per record. Ideal for audit trails and agent pipelines. Costs $0.005 USDC via x402 (requires WALLET_PRIVATE_KEY for a Base wallet).
notarize_inference
Get a cryptographic receipt for one AI inference. Returns a signed Ed25519 attestation, sha256 content hash, and Merkle chain-anchor status for {prompt, response, model_id}. The notary does NOT store your prompt or response — only the hash is retained. Costs $0.001 USDC via x402 (requires WALLET_PRIVATE_KEY for a Base wallet).
notary_pubkeyread-only
FREE — the notary's Ed25519 public key (base64, raw 32 bytes) for fully offline signature verification. No wallet needed.
notary_statsread-only
FREE — live aggregate stats: total notarizations, 24h volume, top models by attestation count, sealed/anchored Merkle batches. No wallet needed.
verify_attestationread-only
FREE — verify any attestation issued by the notary. Supply the attestation_id plus either the original content ({prompt, response, model_id}) or its content_hash. Returns the Ed25519 signature check, hash comparison, and a Merkle inclusion proof once the batch is sealed. No wallet needed.
