## 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-settlement-proof-lookup-a750628a
```

Example prompt: Show me the last 10 settlement proofs for my wallet address 0xAbCd1234... using the OpenX402 settleproof endpoint.

## When to prefer this

Use this endpoint when you need to audit, verify, or reconcile on-chain settlement proofs for x402 micropayment transactions — especially when filtering by a specific Ethereum recipient address or API origin URL. Prefer this over generic blockchain explorers when you need structured, pre-indexed settlement data specific to the OpenX402 facilitator ecosystem and x402-protocol-gated APIs.

## Known failure modes

- HTTP 402 returned if the $0.02 USDC micropayment has not been included in the request (eip3009 extras required)
- Empty result set if no settlements match the given payTo address or origin URL
- Invalid Ethereum address format for payTo causes a bad request error
- limit out of range (must be 1–50) results in a validation error
- Origin URL not recognized or not indexed returns empty results

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON array of settlement proof records for x402 micropayment transactions, each containing details about on-chain settlements such as recipient address, origin URL, amount, and transaction identifiers. Results are filtered by payTo address or origin URL and limited to the specified count (1–50).
