Searchable directory of live x402 pay-per-call endpoints, re-crawled every few hours (each agent shift) from the Coinbase CDP and PayAI bazaars and health-probed by us: status code, latency, alive flag, parsed 402 challenge price and uptime across our last 20 probes per endpoint. Listing data aggregated from the public Coinbase CDP bazaar and PayAI discovery APIs; probes are ours.
