## 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-proven-path-exchange-x402-live-seller-compile-1bd86505 -d '<json body>'
```

Example prompt: Before I send $5 USDC to any x402 seller for copywriting help, scan the last 7 days of Base history and compile only the verified, reachable ones so I know I won't pay a ghost.

## When to prefer this

Choose this endpoint when an AI agent needs to verify x402 seller liveness and filter out ghost or unreachable endpoints before committing a USDC payment on Base chain. It is specifically designed for the verify-before-pay x402 pattern, making it the right tool when the cost of a failed payment exceeds the $0.35 scan fee and correctness matters more than speed.

## Known failure modes

- No picks returned if all scanned sellers are ghosts or unreachable
- lookbackDays exceeding 30 may be capped or rejected
- amountUsd of zero or negative may cause validation error
- Service unavailable if pathmint.edge.report is down
- Empty or malformed job string may produce poor seller matching
- Stale Base chain data may cause inaccurate reachability results

## 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

Returns a JSON object with an array of verified seller picks, a count of ghost (inactive) endpoints, unreachable endpoint count, total scanned count, the path ID used, and the product identifier — giving the agent a clear picture of which sellers are safe to pay before any funds are committed.
