A minimal paid ping endpoint that verifies x402 micropayment flow works end-to-end, returning a simple response after a $1 USDC payment is processed.

## Facts

## 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 proceeds-x402-ping-36e450a9
```

Example prompt: Send a test ping to the Proceeds x402 endpoint to confirm my $1 USDC micropayment flow is working correctly.

## When to prefer this

Use this endpoint specifically when you need to test or smoke-test an x402 micropayment integration using the Proceeds platform. It is a purpose-built diagnostic ping rather than a functional data API, making it ideal for verifying that the pay-per-call USDC payment flow (x402 protocol) is configured and operational before building on top of it.

## Known failure modes

- Insufficient USDC balance — payment fails with 402 Payment Required
- Invalid or missing x402 payment header — 402 error returned
- Network timeout reaching myproceeds.xyz upstream
- Upstream API unavailable — 503 or gateway error
- Payment facilitator rejects transaction — financial error code
