Buy the right paid API for your agent in one call

Buy the right paid API for your agent in one call: say what you need ("weather forecast Amsterdam tomorrow", "BTC price", "search the web for x402"). Fizzl picks the x402 service x402 Doctor has seen paying out day after day at a fair price, fills in its input, buys it (up to $0.01) and returns the answer, checked by TypeSafe Jev, with a signed receipt. Nothing is charged when no service delivers.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
