 While Server Functions can be a good way to write server-side code for data needed by your UI, sometimes you need to expose API routes.
 Some reasons for wanting API Routes include:
-- there are additional clients that want to share this logic.
-- exposing a GraphQL or tRPC endpoint.
-- exposing a public facing REST API.
-- writing webhooks or auth callback handlers for OAuth.
-- having URLs not serving HTML, but other kinds of documents like PDFs or images.

 For these use cases, SolidStart provides a way to write these routes in a way that is easy to understand and maintain. 
 API routes are just similar to other routes and follow the same filename conventions as [UI Routes](/solid-start/building-your-application/routing).
