## 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-fac-vs-drift-diagnostics-endpoint-ac695626
```

Example prompt: Run the facvsdrift diagnostic on OpenX402 and show me the paid JSON response — I want to see the SKU, title, and price returned after the $0.03 USDC payment clears.

## When to prefer this

Choose this endpoint when you need to test, demonstrate, or validate the x402 micropayment protocol with a real paid SKU using OpenX402 as the facilitator and eip3009 token authorization. Ideal for developers building x402-compatible agents or verifying payment-gating behavior in a live environment.

## Known failure modes

- HTTP 402 returned if payment header is absent or invalid — response includes eip3009 payment extras
- Payment rejected if facilitator is not OpenX402
- Malformed properties parameter may result in unexpected behavior
- USDC payment insufficient or wrong token type causes authorization failure

## 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 SKU name ('facvsdrift'), a diagnostic note, the price ('$0.03'), and the title ('Fac Vs Drift'). Unpaid requests receive HTTP 402 with eip3009 payment-required metadata instead.
