Before / After

Without APIBUILD

Build me an API for users and posts.

With APIBUILD

APIBUILD A REST API for a blog. Users can sign up, post articles, comment, and like. JWT auth. Postgres backend.

What changes in Claude's response

Claude returns: route definitions, handler functions, request/response schemas, input validation, JWT middleware, the SQL migrations, and an OpenAPI spec you can paste into Postman. Every endpoint has the validation rules inline so you can read the API contract without leaving the code.

When NOT to use APIBUILD

Don't APIBUILD for non-CRUD work. The code is great for standard REST patterns and bad for things like real-time, streaming, or complex auth flows.
