## 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 settled-seller-reputation-lookup-by-payto-address-2f8a950c
```

Example prompt: Before I pay this x402 endpoint, can you check the seller reputation for payTo address 0x1234abcd... on Settled — I want to know how many live endpoints they run, whether they're flagged as a clone farm, and how many settlements they've had on Base in the last 30 days?

## When to prefer this

Use this endpoint when you need to assess the trustworthiness of a specific x402 seller before authorizing payment, when vetting new API vendors whose payTo address you have, or when you want on-chain evidence of real economic activity rather than just metadata claims. Prefer this over generic blockchain explorers because it aggregates x402-specific signals (liveness, clone-farm detection, quote-only flags) alongside raw settlement counts in one call.

## Known failure modes

- Address not found — no endpoints or on-chain activity linked to this wallet returns empty or 404
- Invalid address format — non-EVM/non-Solana strings return a validation error
- Address has zero on-chain activity — all settlement counts return as 0 with null last-settlement time
- Network errors or Base RPC timeouts may cause stale or incomplete on-chain data

## How this service works

Seller reputation by payTo address: whether its on-chain sales look organic or self-generated (payer concentration, single-source funding and circular flows, labelled organic / concentrated / single_source / circular), settlements and unique payers on Base over 30 days, how many endpoints it serves and how many are live, price range, and clone-farm and quote-only flags.

## Output

A JSON object describing the seller behind the given payTo address: total endpoints served, count of currently live endpoints, price range across their endpoints, boolean clone-farm and quote-only flags, and 30-day on-chain Base statistics including total settlements, unique payers, and timestamp of the most recent settlement.
