# Vendors

> The vendor landscape behind OneShot's tools.

OneShot's tools run on third-party vendors. Which vendor serves a given call is
our problem, not yours: you call `local/search`, we pick the provider, and you
get one price and one receipt.

This page maps that landscape by category. It is a directory of who operates in
each space — not a list of live wiring. The provider behind any endpoint is
selected per call and changes as we add and retire sources.

Categories we build in-house are not listed: commerce, compute, web search,
web read, email sending and LLM routing.
