## 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 proxy402-paywalled-resource-spo3lzu-l6-da6abfab -d '<json body>'
```

Example prompt: Fetch the content behind the Proxy402 short link Spo3LZu_l6 — go ahead and pay the $1 USDC access fee using x402 to unlock whatever resource is behind it.

## When to prefer this

Use this endpoint when you specifically need to access the resource behind the Proxy402 short URL Spo3LZu_l6 and are prepared to spend $1 USDC per call via the x402 micropayment protocol. This is appropriate for agents with crypto wallets integrated with x402-compatible payment flows.

## Known failure modes

- Insufficient USDC balance — payment cannot be fulfilled, 402 response returned
- Invalid or missing x402 payment header — authentication fails
- Resource behind the proxy is unavailable or has changed — upstream error
- Network timeout reaching proxy402.com
- Payment processed but upstream resource returns an error (4xx/5xx)

## How this service works

Payment for GET https://proxy402.com/Spo3LZu_l6

## Output

The agent receives the HTTP response body of the proxied resource after the $1 USDC x402 payment is processed — this could be JSON data, text, or other content depending on what the proxy URL points to. The exact content type and structure of the underlying resource is unknown without calling the endpoint.
