> Settled Seller Reputation by payTo Address is a paid API for AI agents from settled.justinedwardvolmer.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Returns seller reputation data for an x402 endpoint operator by their payTo address, including endpoint counts, liveness stats, price range, clone-farm and quote-only flags, and 30-day on-chain activity on Base.

## 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-by-payto-address-a3e91b8d
```

Example prompt: Before I pay this x402 endpoint, can you check the reputation of its payTo address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — I want to know how many live endpoints they run, whether it's 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 trust in an x402 operator before paying their endpoint, want to detect clone farms or quote-only sellers, or need to verify real on-chain payment activity on Base. Prefer this over general blockchain explorers when you specifically want x402-context reputation signals like endpoint liveness counts, price ranges, and payer diversity.

## Known failure modes

- Address not found — no data indexed for the provided payTo address
- Invalid address format — address does not match EVM (0x…) or Solana format
- Upstream indexing lag — recent settlements may not yet be reflected
- Rate limiting or payment failure — $0.002 USDC x402 payment required per call

## How this service works

Seller reputation by payTo address: how many endpoints it serves, how many are live, price range, clone-farm and quote-only flags, and on-chain activity on Base (settlements and unique payers over 30 days, last settlement time).

## Output

Returns a reputation profile for the given payTo address including: total and live endpoint counts, price range across their endpoints, boolean flags for clone-farm and quote-only status, and Base on-chain metrics covering settlement count and unique payer count over 30 days plus the timestamp of the last settlement.
