How is this data sourced?
Each listing is cross-walked from agentic.market's curated catalog with the Coinbase Developer Platform x402 discovery feed
(api.cdp.coinbase.com/platform/v2/x402/discovery/resources).
Revenue figures are derived from eth_getLogs on USDC Transfer
events to each operator's published payTo wallet on Base mainnet, fully reproducible from the public RPC.
Refreshed every 6 hours for listings; revenue refresh runs daily.
