x402 Verified Directory API for agents
Find live x402 endpoints worth paying, by capability: returns only endpoints Delx has live-probed, each with liveness score, last-observed timestamp, observed price, response-shape validity and Agents Hive ban-list status; every row cites its probe receipt, and ghost endpoints and dead quotes are filtered out before you spend. Limitation: observations, not endorsements — freshness is bounded by the last probe cycle, and absence from the directory means unprobed, not unsafe — $0.01 USDC per paid call through x402.
