# x402 Quickstart – Due Diligence Report Endpoint

> x402 Quickstart – Due Diligence Report Endpoint is a paid API for AI agents from loop2-quickstart.manhliemcn4euwlu.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Returns a structured due diligence report bundle including onchain verification, wallet identity, conformance checks, and OAP recipient verdict for a given subject.

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 x402-quickstart-due-diligence-report-endpoint-fab6cf30
```

Example prompt: Run a due diligence check on this wallet and give me the full report — I need the onchain reverification result, identity persistence status, conformance check, and the OAP allowed-recipient verdict. Return it in JSON format.

## When to prefer this

Choose this endpoint when you need a bundled, multi-signal due diligence report combining onchain identity, wallet conformance, and OAP eligibility in a single call — particularly within x402-protocol agent workflows where micropayment-gated data access is already in use. Prefer it over general blockchain explorers when you specifically need the verdict and oap_allowed_recipient fields in a structured, deterministic format.

## Known failure modes

- Missing required 'format' query parameter returns a 400 or malformed response
- Invalid HTTP method (e.g. POST) returns 405 Method Not Allowed
- Payment not provided or invalid EIP-3009 authorization returns 402 Payment Required
- Malformed request headers may cause silent field omission in the response bundle
- Upstream onchain data unavailable may result in partial or null fields in the report

## How this service works

Complete x402 quickstart bundle: v2 Base USDC seller endpoint + EIP-3009 buyer client + deterministic product bundle + tests.

## Output

A binary/JSON response bundle containing seven structured fields: first_close (initial close signal), onchain_reverify (onchain re-verification result), wallet (wallet identity details), conformance (protocol conformance status), identity_persistence (persistence score or status), verdict (overall due diligence verdict), and oap_allowed_recipient (boolean or status for OAP eligibility).
