## 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-opt-get-drift-diagnostics-dfc1dbbf
```

Example prompt: Run the optgetdrift x402 diagnostic against https://example.com/api/resource using a GET request and tell me what drift or payment-gate metadata you see.

## When to prefer this

Choose this endpoint when you need to programmatically diagnose x402 protocol compliance, inspect EIP-3009 payment header extras, or measure drift on a payment-gated HTTP endpoint using the OpenX402 facilitator. It is specifically suited for developers building or debugging x402-gated APIs, not for general HTTP health checks or non-x402 payment systems.

## Known failure modes

- HTTP 402 returned if payment is not included — includes EIP-3009 extras for payment resolution
- Invalid or unreachable target URL results in a diagnostic error
- Non-GET/HEAD/DELETE HTTP method submitted will fail schema validation
- Missing required 'input.type' or 'input.method' fields cause request rejection
- Facilitator other than OpenX402 is not supported and may be rejected

## 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 ('optgetdrift'), a human-readable title, the price ($0.02 USDC), and diagnostic notes about the x402 payment gate configuration and any drift detected on the target URL. Unpaid requests receive HTTP 402 with EIP-3009 payment extras instead.
