Pick the check that matches your decision. Once it passes, the result is saved as proof, and the next decision reads that proof instead of asking again.

​
What you can verify

The verifier catalog lists every check and its inputs.

​
How checks run

Most product gates start with interactive checks. Use instant and lookup checks when your rule needs them.

​
What you get back

  • A proof ID in qHash
  • A status of verified, processing, or failed
  • A proof page at https://proofable.me/proof/{qHash}
  • A hosted link, only when the person must finish a step in the browser
When the status is processing, poll with pollProofStatus until it finishes.
