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 pathmint-x402-pay-clearance-compiler-b76d5820 -d '<json body>'
```

Example prompt: Before I pay this x402 challenge, check the payTo address 0xABC123... and the raw Payment-Required body to see if I should proceed or abort — I'm about to send $5 USDC and I want to know my net if I abort versus the avoided loss.

## When to prefer this

Use this endpoint when an AI agent or automated system is about to fulfill an x402 HTTP 402 payment challenge and needs a verified, fee-aware PROCEED/ABORT verdict before committing USDC. It is specifically designed for the x402 protocol's payTo/Payment-Required pattern and calculates net economics (stake vs fee vs avoided loss), making it more useful than generic address validators or payment simulators that don't understand x402 semantics.

## Known failure modes

- Invalid or malformed payTo address returns validation error
- Missing paymentRequired body causes incomplete analysis and may default to ABORT
- amountUsd of zero or negative triggers input rejection
- Unrecognized or non-standard x402 Payment-Required format may reduce verdict confidence
- Network timeout on edge node returns 5xx with no verdict

## How this service works

Proven Path Exchange — compile sealed procedures when the savings vs the fee are checkable. Primary: verify-before-pay clearance of an x402 payTo.

## Output

A JSON object with a verdict field ('PROCEED' or 'ABORT'), the stake amount in USD, the net savings if aborting (net_if_abort_usd), the avoided loss if aborting (avoided_loss_if_abort_usd), and the path and product identifiers used for the check.
