AI coding: generating API clients from OpenAPI specs
Feed the spec, name the language and HTTP library, and demand exhaustive coverage of error responses. AI excels at this transcription work.
11 min · Reviewed 2026
The premise
Hand-written API clients drift from specs. AI generation from OpenAPI produces typed clients in minutes — but only if you specify error handling, retries, and auth model up front.
What AI does well here
Translate schemas into typed request/response models
Generate one method per endpoint with correct verbs
Map documented error codes to typed exceptions
What AI cannot do
Infer auth flows that aren't in the spec
Decide retry and timeout policy for your use case
Test against the live API for you
