## 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-tools-friendssurf-paid-diagnostic-endpoint-101db1bd
```

Example prompt: Can you hit the x402 friendssurf diagnostic endpoint and confirm I get back a valid paid JSON response — the SKU should be 'friendssurf' and the price should show $0.02 — using OpenX402 as the facilitator?

## When to prefer this

Use this endpoint when you need to test or validate x402 micropayment protocol integration, specifically the EIP-3009 payment flow with OpenX402 as facilitator. It is purpose-built as a diagnostic tool for developers building or debugging x402-gated APIs, not for production data retrieval.

## Known failure modes

- HTTP 402 returned when payment header is missing or invalid — includes eip3009 extras with payment instructions
- Incorrect USDC amount in payment header causes 402 rejection
- Facilitator other than OpenX402 not accepted, resulting in payment failure
- Malformed properties parameter may cause unexpected response
- Network timeout on slow payment settlement

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON object containing the SKU name ('friendssurf'), a diagnostic note explaining this is an example paid JSON shape, the price ('$0.02'), and the title ('Friends Surf'). Unpaid requests return HTTP 402 with EIP-3009 payment extras indicating the required USDC amount and facilitator details.
