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 openclaw-x402-signals-diagnostics-3db22a7c
```

Example prompt: Run a diagnostic probe on the OpenClaw x402 signals endpoint — I want to see if it correctly returns an HTTP 402 with EIP-3009 payment extras when I haven't paid, and then fetch the actual signal data after paying the $0.05 USDC fee via OpenX402.

## When to prefer this

Choose this endpoint when you need a live x402 protocol test target that correctly implements HTTP 402 with EIP-3009 payment extras via the OpenX402 facilitator. Ideal for developers building or debugging x402-compatible payment clients, testing facilitator integrations, or validating that EIP-3009 payment flows work end-to-end. Not suitable for production signal data or non-x402 payment testing.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is included — expected behavior, includes EIP-3009 payment challenge
- Payment processed by unsupported facilitator (only OpenX402 is accepted) — request rejected
- Invalid or expired EIP-3009 signature — payment authorization fails
- Network timeout or endpoint unavailability — no diagnostic data returned
- Malformed properties parameter — may return error or empty signals

## 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 signal data from the endpoint. Without payment: HTTP 402 response containing EIP-3009 payment authorization extras specifying the required USDC amount, recipient, and payment parameters needed for the OpenX402 facilitator to process the transaction.
