For agents: call
x402_service_search over MCP (https://logicnodes.io/mcp/v2) or POST https://logicnodes.io/v1/tools/x402_service_search {"query":"weather"} to get the best live endpoint with an example input. For sellers: claim your listing, add the badge, or get alerts when your API stops answering (x402_monitor_create, $5 for 30 days). JSON: /v1/observatory/providers.Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. Directories read 19 h ago. LogicNodes does not run these services or take a cut.
