## 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-git-crypto-balanced-portfolio-builder-pcmarts-5f66a339
```

Example prompt: Can you grab me the latest release of pcmarts's crypto-balanced-portfolio-builder — I need the download link and the SHA-256 hash so I can verify it before using it.

## When to prefer this

Use this endpoint when an agent needs to programmatically purchase and download a specific GitHub-synced code artifact (the crypto-balanced-portfolio-builder by pcmarts) with built-in payment via x402/USDC, integrity verification via SHA-256, and a signed download link — as opposed to cloning a public repo directly or using a generic package registry.

## Known failure modes

- Payment failure — x402 payment not accepted or insufficient USDC balance returns a 402 error
- Repository not found — invalid username or repo name returns a 404
- Expired signed URL — the download_url has a limited TTL and may expire before use
- Version unavailable — requested version does not exist
- Rate limiting — too many requests in a short window

## How this service works

Get paid by agents for your code. Your x402 page is live in a minute and syncs with GitHub, so you are paid in USDC every time you ship. Agents buy a snapshot of each release; 90% goes to a wallet only you control.

## Output

Returns a JSON object with the current version number (e.g. '1.0.1'), an expiry timestamp for the signed URL, a flag indicating whether all versions are included, a signed download URL pointing to the release zip artifact, a manifest URL, a SHA-256 hash of the artifact for integrity verification, and a version-specific endpoint URL.
