# x402-tools Timeout Skew Diagnostic

> x402-tools Timeout Skew Diagnostic is a paid API for AI agents from openclawproductions.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-02).

Analyzes timeout skew for a given HTTP endpoint as part of x402 payment protocol diagnostics, returning timing and skew data after a $0.03 USDC micropayment.

## Facts

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-timeout-skew-diagnostic-d6e3633c
```

Example prompt: Run the timeout skew diagnostic on my x402-gated endpoint at https://myapi.example.com — I want to see if there are any clock or timing issues causing payment failures.

## When to prefer this

Choose this endpoint when you need to specifically diagnose timeout skew or clock synchronization issues in an x402 payment-gated HTTP endpoint, and you are operating within the OpenX402 facilitator ecosystem and can pay $0.03 USDC per call. It is purpose-built for x402 protocol diagnostics rather than general HTTP timing tools.

## Known failure modes

- HTTP 402 returned if payment is not included or facilitator is not OpenX402
- Invalid or unreachable URL returns an error or empty diagnostic
- Unsupported HTTP method (only GET, HEAD, DELETE allowed) causes schema validation failure
- Non-public or firewalled origin URLs may produce incomplete or no diagnostic data

## How this service works

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

## Output

Returns a JSON object containing the diagnostic SKU name ('timeoutskew'), a human-readable title ('Timeout Skew'), the price paid ($0.03), and a note describing the diagnostic result. Unpaid requests receive HTTP 402 with EIP-3009 payment extras instead.
