x402 APIPassing, checked 26 min ago

Signed check of an x402 endpoint before you pay it: who really pays it on Base (settlements and unique payers over 30 days), a fresh unpaid probe (cached ≤5 min) with status, latency and the parsed quote, payability, paying agents' reports, the seller's claim, the scout's last real purchase (settlement transaction and whether it matched the listing), a quality score and risk flags. Free up to 300 calls a day per client at /v1/free/check.
