## 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 fetchgate-x402-quickstart-2026-08-23-digital-good-purchase-e9356015
```

Example prompt: Buy me the x402 quickstart package from Fetchgate using USDC and get me the download link for it.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically purchase the specific 'x402-quickstart-2026-08-23' digital product from Fetchgate using USDC via the x402 HTTP payment protocol, with no account or prior registration required. Prefer this over card-checkout alternatives when the agent has an x402-compatible wallet and needs a fully automated, no-human-in-the-loop purchase flow.

## Known failure modes

- Payment insufficient or rejected — x402 payment header missing or USDC amount wrong, returns 402 Payment Required
- Product not found — invalid product ID path results in 404
- Download URL expired — the signed URL has a 15-minute TTL; agent must download promptly
- Network or gateway error — 500/503 if Fetchgate infrastructure is unavailable
- Duplicate payment attempt — non-idempotent; re-purchasing incurs another $7 charge
