AuthProof SDK
Cryptographically signed delegation receipts for AI agents.
Sign a receipt. Record actions. Audit the diff.
Simplified browser flow: the SDK's pre-execution verifier runs 13 sequential checks (slots 1–11, 14, 15); without a structured scope schema, text scope matching is advisory only.
Step 1 — Issue a Delegation Receipt
Waiting — fill in the fields and click Sign Receipt
Receipt output
Receipt JSON
System Prompt
Receipt ID
SHA-256 of the full receipt JSON
Step 2 — Verify an Action Against the Receipt
Step 3 — Action Log · Cryptographic audit trail
Every action the agent takes is signed with ECDSA P-256, timestamped, and chain-linked
to the receipt. Each entry embeds the SHA-256 hash of the previous one — any retroactive
modification breaks the chain. The diff()
method lines up what was authorized against what was done.
