# x402-tools Source Placeholder Diagnostic (srcph)

> x402-tools Source Placeholder Diagnostic (srcph) is a paid API for AI agents from openclawproductions.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-20).

Returns a paid diagnostic JSON payload for the 'srcph' SKU, gated by x402 micropayment; 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-source-placeholder-diagnostic-srcph-cdb71fb0
```

Example prompt: Run the x402 srcph diagnostic against the openclawproductions endpoint using a GET request and show me the response — I want to confirm the micropayment gating and EIP-3009 extras are working correctly.

## When to prefer this

Choose this endpoint when you need to test or verify x402 micropayment protocol integration, specifically with the OpenX402 facilitator. It is ideal for probing the HTTP 402 / EIP-3009 response shape, confirming that payment gating is correctly enforced, or validating a paid API flow end-to-end in a safe diagnostic context before building against real production endpoints.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras when no valid x402 payment token is provided
- Invalid or unsupported HTTP method (only GET, HEAD, DELETE accepted) returns an error
- Malformed series_ticker parameter may cause unexpected behavior or ignored parameter
- OpenX402 facilitator unavailable causes payment verification to fail
- Network timeout or service unavailability on openclawproductions.com

## 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 name ('srcph'), a diagnostic note clarifying it is an example shape and not a live settlement, the price ('$0.03'), and the title ('Source Placeholder'). If payment has not been made, returns HTTP 402 with EIP-3009 payment authorization details instead.
