Utified – Developer Utility Toolkit

Reverse Tools — receipt verifier

Paste any Utified signed receipt to discover which tool produced the output, with what settings, and confirm it hasn't been tampered with.

Receipts are HMAC-SHA256 signed and tamper-evident. Verification runs server-side so the secret never reaches the browser. Anyone holding a valid receipt can verify it here — no account required. Where do you get a receipt? From GET /api/v1/jobs/<id>/receipt (single tool jobs) or GET /api/v1/chain-runs/<id>/receipt (chain runs), or the "Receipt" button on your Account → Activity Feed and chain detail pages.
