## 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 warppay402-public-data-feed-6098eb4a
```

Example prompt: Fetch the file called 'market_summary.json' from the WarpPay402 public data feed — it uses x402 micropayment so go ahead and pay the $0.001 USDC charge.

## When to prefer this

Use this endpoint when you need to retrieve a specific named file from the WarpPay402 monetized public data feed and your agent supports x402 micropayment (paying $0.001 USDC per call). Prefer this over generic HTTP file fetches when the data is gated behind the x402 protocol and you want non-custodial, per-call access without a subscription.

## Known failure modes

- File not found: requested filename does not exist in the feed, returning a 404 or error status
- Payment failure: x402 micropayment not authorized or insufficient USDC balance
- Invalid filename format: filename parameter missing or malformed
- Server error: upstream data feed unavailable, returning 5xx
- Access denied: payment not accepted or wallet not whitelisted
