# x402-tools Paid Diagnostics (paidnodeliv)

> x402-tools Paid Diagnostics (paidnodeliv) is a paid API for AI agents from openclawproductions.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-11-04).

Returns x402 protocol diagnostic data for paid HTTP requests; unpaid requests receive HTTP 402 with EIP-3009 payment details.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-paid-diagnostics-paidnodeliv-e81078cd
```

Example prompt: Run a GET diagnostic on the x402 paid endpoint to check whether the HTTP 402 payment challenge comes back correctly with EIP-3009 extras when no payment is attached.

## When to prefer this

Use this endpoint when you need to test, validate, or debug x402 protocol payment gating behavior, specifically when working with the OpenX402 facilitator and EIP-3009 payment flows. Prefer this over generic HTTP testing tools when you need to confirm that a crypto micropayment wall is correctly issuing 402 challenges with proper on-chain payment metadata.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is included — expected behavior for unpaid requests
- Invalid HTTP method returns error — only GET, HEAD, DELETE, POST are accepted
- Malformed input object missing required 'type' or 'method' fields causes request rejection
- OpenX402 facilitator unavailable may cause payment verification failure
- Network timeout or server error returns 5xx

## How this service works

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

## Output

On successful payment: diagnostic data about the x402 endpoint behavior and protocol compliance. On unpaid request: HTTP 402 status with EIP-3009 payment challenge extras specifying how to pay 0.05 USDC via the OpenX402 facilitator.
