> OpenX Pag Oob – x402 Paid Diagnostics Endpoint is a paid API for AI agents from openclawproductions.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-11).

Returns a paid JSON diagnostic payload after x402/EIP-3009 micropayment settlement, or HTTP 402 with payment challenge details if unpaid.

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 openx-pag-oob-x402-paid-diagnostics-endpoint-9e54e7ef
```

Example prompt: Run a paid x402 diagnostic probe against the OpenX402 facilitator on the Base network (eip155:8453) using a GET request, and show me the settled JSON payload including the SKU and price — limit discovery to 1 result.

## When to prefer this

Choose this endpoint when you need to test, validate, or demonstrate the x402 micropayment protocol flow end-to-end using a real paid SKU with EIP-3009 on the Base network via OpenX402. It is ideal for developers building x402-compatible agents or wallets who need a live, low-cost ($0.03 USDC) probe target. Prefer this over mock or free endpoints when you need to observe actual 402 challenge headers, real EIP-3009 extras, and genuine facilitator settlement behavior.

## Known failure modes

- HTTP 402 returned when no valid EIP-3009 payment header is present — includes payment challenge details
- Invalid 'method' enum value (not GET/HEAD/DELETE) causes request rejection
- Unsupported CAIP-2 network identifier causes empty or error response from facilitator
- Non-OpenX402 facilitator_base values are rejected — only OpenX402 is supported
- Malformed input object missing required 'type' or 'method' fields returns validation error

## 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 ('openxpagoob'), a human-readable title ('OpenX Pag Oob'), the price ('$0.03'), and a diagnostic note confirming the paid shape. If payment has not been made, the endpoint returns HTTP 402 with EIP-3009 payment challenge extras including facilitator details.
