## 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 earn-shop-fetchclean-pdf-download-fa6019be -d '<json body>'
```

Example prompt: I want to buy and download the FetchClean PDF document from Earn Shop — use my x402 payment payload to pay the 0.02 USDC on Base and give me the file.

## When to prefer this

Choose this endpoint when you need to programmatically purchase and download a specific gated PDF document using a USDC micropayment on Base, either via the x402 protocol payment header or a direct USDC transfer with tx hash. Ideal for AI agents that need to acquire digital documents autonomously without a traditional subscription or API key.

## Known failure modes

- Invalid or malformed x402 payment payload returns an error and triggers refund
- Transaction hash not found or insufficient USDC transfer amount causes rejection
- Payment not yet confirmed on Base blockchain leads to delivery failure and refund
- Document unavailable or server error results in refund to payer
- Duplicate payment submission may be rejected to prevent double-spend

## How this service works

Pay-per-download PDF documents in USDC on Base via the x402 protocol. Settlement runs through the public x402 facilitator; a direct transfer + tx-hash route is also accepted. Failed delivery is refunded.

## Output

Returns the purchased PDF document as a raw binary file stream. If payment fails or delivery cannot be completed, the USDC payment is refunded to the sender.
