Api Endpoint

x402 Intelligence API

x402 market intelligence with current catalog-attributed USDC flow, address-level demand signals and separately labeled value-matched history. The headline covers Base only (market.universeChains); the multi-chain picture ships alongside it as ecosystem, split into an RPC-proven floor and an indexed upper bound that are not additive (notASum). Attribution is not exclusive protocol-intent proof.
