# Lumière PayCheck

> Trust scores for x402 payment endpoints. Before an AI agent pays an x402 API, PayCheck checks the endpoint, its price and its payout wallet and returns a verdict (proceed, caution or avoid) with a 0-100 score. It monitors the endpoints listed in the x402 Bazaar (90,169 at last count) and makes small real test payments to confirm endpoints deliver what they charge for. Payments on Base and Solana. Operated by Lumière LLC, Connecticut.
