### Description (declared)

Ask before you pay: PulseFeed tells an AI agent whether an x402 payment endpoint is safe to pay — liveness, anomaly scan (receiver-address changes between observations, catalog price vs. challenge price, invalid receivers, asset/network mismatch), on-chain receiver verification on Base, and an open 0-100 Trust Score. Built on a continuous independent audit of the x402 ecosystem (23340 endpoints probed of 30227 tracked, 17% of probed dead or invalid) plus a security audit of the MCP server ecosystem.
