x402 Data API

What a wallet spent on x402 APIs on Base in the last days, read from the chain: total, per seller (named by the Bazaar listings that pay to it), per day, and the recent payments, with other USDC transfers counted apart. For a wallet with very many payments, complete is false and from says how far back it was read.
