# WhiteMagic Continuity-Receipt Verification

> WhiteMagic Continuity-Receipt Verification is a paid API for AI agents from api.whitemagic.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-01).

Verifies a signed continuity receipt bundle and returns a trust verdict (TRUSTED, PROVISIONAL, INSUFFICIENT_EVIDENCE, or UNTRUSTED) with coded errors and an optional signed verification receipt.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability whitemagic-continuity-receipt-verification-b317a19b -d '<json body>'
```

Example prompt: Can you verify this signed continuity receipt bundle and tell me whether it comes back as TRUSTED, PROVISIONAL, INSUFFICIENT_EVIDENCE, or UNTRUSTED — and include any coded errors in the result?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
