02 — Type-safe












§ 02 — How it works
One pattern between your code and every provider.
Your application talks to APIFold. APIFold talks to each provider through a standalone, typed adapter.

01
Connect once
Name a provider and pin a version. APIFold loads the matching adapter and returns a client with one consistent interface.


02
Call with types
Every endpoint, parameter, and response is typed. Errors come back as typed unions, so mistakes surface at build time.


03
Upgrade on your schedule
Each adapter is versioned independently. Move one provider to a new version without touching the rest of your integrations.












§ 03 — Features
