How this service works
WhiteMagic continuity-receipt verification: POST a signed receipt bundle and receive a verdict (TRUSTED / PROVISIONAL / INSUFFICIENT_EVIDENCE / UNTRUSTED) with coded errors and an optional signed verification receipt. Verification is stateless, offline-verifiable, and fail-closed; keyless /health, /info, /revocations and GET /anchors remain free.
Output
A JSON verdict object containing one of four trust levels (TRUSTED, PROVISIONAL, INSUFFICIENT_EVIDENCE, UNTRUSTED), an array of coded error descriptors explaining any issues, and optionally a signed verification receipt that itself can be used as offline-verifiable proof of the check.
Example use cases
Agent output provenance check
“I need you to verify this signed receipt bundle from our AI agent's last run and tell me if the result comes back TRUSTED or if there are any coded errors — we need to confirm the output hasn't been tampered with before we act on it.”
Automated pipeline receipt gate
“Before our pipeline proceeds to the next stage, verify this signed continuity receipt bundle and only continue if the verdict is TRUSTED — if it's PROVISIONAL or UNTRUSTED, surface the error codes so we can investigate.”
Audit compliance receipt validation
“For our compliance audit, please submit this signed receipt bundle for verification and give me the full verdict along with the optional signed verification receipt so we have a chain of evidence on file.”
Technical details
Endpoint
POSThttps://api.whitemagic.dev/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need stateless, fail-closed, offline-verifiable trust verdicts on signed continuity receipt bundles — particularly in agentic pipelines where tamper-evidence and cryptographic provenance matter. It is purpose-built for receipt bundle verification with structured verdict codes, unlike generic signature checkers or hash validators.
Side effects
- Malformed or unsigned receipt bundle returns UNTRUSTED with coded errors
- Insufficient evidence in the bundle returns INSUFFICIENT_EVIDENCE verdict
- Revoked keys or anchors cause UNTRUSTED verdict
- Missing required fields in the POST body result in a validation error response
- Payment failure (x402) blocks the call before verification occurs
