For current conditions and multi-day forecasts an agent can either use an MCP server or pay per call over x402 with no API key. The table puts services with real, wash-filtered on-chain usage first.
Verified buyers are counted per service; one wallet that pays several services counts once for each. Some services share a payout wallet with other services, which we flag.
