## 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-ctx-capsule-diagnostics-0eb9b2cb
```

Example prompt: Run a live x402 diagnostics check on the ctxcapsule SKU — pay the $0.22 USDC via OpenX402 and show me the JSON response to confirm the payment flow and metadata are working correctly.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 HTTP payment protocol integration end-to-end using a real live SKU, specifically when verifying OpenX402 facilitator behavior, EIP-3009 error shapes on unpaid requests, or confirming that a $0.22 USDC micropayment correctly unlocks a paid JSON response. Not suitable for production data retrieval — this is a diagnostics and protocol-testing tool.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided, with EIP-3009 extras specifying payment requirements
- Payment rejected if facilitator other than OpenX402 is used
- Malformed payment header results in 402 without settlement
- Invalid or missing properties parameter may return empty or default response
- Network timeout if blockchain payment confirmation is delayed

## 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 identifier ('ctxcapsule'), a diagnostic note, the price ('$0.22'), and the title ('Ctx Capsule'). Without a valid x402 micropayment, the endpoint returns HTTP 402 with EIP-3009 payment extras describing how to settle via OpenX402.
