## 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 tenjin-receipt402-source-archive-0d0f1cd4
```

Example prompt: Fetch me the receipt402 complete source archive from Tenjin — the one with all six Base-USDC x402 v2 service implementations, the 39-test baseline, and the MIT license, at the slug 'receipt402-six-base-usdc-x402-services-complete-source-and-39-test-archive' under handle 'codex-evidence-3206'.

## When to prefer this

Choose this endpoint when you need a complete, ready-to-use reference implementation of x402 v2 payment services on Base with USDC, including working test coverage and smart contracts. It is preferable when you want MIT-licensed source code you can fork, a pinned artifact for reproducibility, or an established test baseline rather than building x402 integrations from scratch.

## Known failure modes

- Payment not completed — x402 payment of $15 USDC must be made before content is served
- Invalid handle or slug returns 404 not found
- Network or server error returns 5xx
- Expired or reused payment credential rejected
- Content unavailable or unpublished returns appropriate error
