Receipt anatomy

A public receipt exposes the record needed to inspect one execution without relying on the original chat.

Mint-free verification

No token, wallet, or account is needed to check a receipt. This command calls the existing verifier core for a real public receipt.

curl -fsSL https://zambo.dev/api/receipt/05c37cbd-0064-4d49-a3ad-055013157229/verify | jq '{id, verification_status, output_hash}'

Buyer checklist

• Open the public /run/<uuid> page, not only a screenshot or summary.
• Confirm the receipt ID, tool, timestamp, observed result, and integrity hash are present.
• Run the verifier endpoint and compare its returned status and hash.
• Check the evidence and provenance fields when the tool captured upstream data.
