do $0.02 per call

One endpoint for everything (OpenRouter-style): describe what you need and pass the input; Toll402 picks the best tool from the whole catalog (built-in, community-forged, external x402 services) and runs it. Tools priced above maxPriceUsd are returned as a match instead of executed.

For AI agents: call do

{
 "need": "convert 100 US dollars to Mexican pesos",
 "input": {
  "base": "USD",
  "quote": "MXN",
