MCPFax Public-Data Utility

Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."

31 keyless public-data endpoints for AI agents: geocoding, weather, air quality, VIN decode, FX, stock quotes, SEC company facts, holidays, LEI, DNS. $0.001–$0.004 USDC per call on Base (x402 v1+v2); errors are free — a call that returns no data settles nothing.
