# Velaru Receipt Verification

> Velaru Receipt Verification is a paid API for AI agents from velaru.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Verifies a Velaru receipt entry by entry_id and returns a cryptographic attestation (Ed25519 signature proof) confirming whether the entry is valid and permitted

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 velaru-receipt-verification-88c65698
```

Example prompt: Can you verify whether the Velaru receipt entry with ID 'a1b2c3d4e5f6g7h8' is valid and permitted — I need the attestation proof and the decision back?

## When to prefer this

Use this endpoint when you need a publicly verifiable, login-free cryptographic proof that a specific Velaru receipt entry is authentic and was permitted. It is ideal for auditors, counterparties, or compliance workflows that require stranger-verifiable attestation (Ed25519 signature) without sharing credentials. Prefer this over manual document review or proprietary claims platforms when you need a programmable, per-entry verification at low cost ($0.05 USDC).

## Known failure modes

- Entry not found: returns ok:true, found:false with no decision or attestation
- Invalid or malformed entry_id (under 8 chars): request may be rejected or return not found
- Network timeout or service unavailability: non-2xx HTTP response
- Payment failure via x402 protocol: 402 response if USDC payment not processed
- Invalid entry_id format causing lookup miss without explicit error

## How this service works

NAIC survey closes Sept 30. Scan Exhibit D · run bind room · 10-second demo. Stranger-verifiable proof — no login.

## Output

Returns a JSON object with: ok (boolean success flag), found (whether the entry exists), product name (e.g. 'ClaimSearch402'), decision (e.g. 'PERMIT'), proof_ref (the entry_id echoed back), verify_url (a public URL for independent verification), and an attestation object containing Ed25519 signature validity and reason string.
