YOUR INPUTS
Build your result
Complete every field. The result updates only when you choose Calculate.
How it works
Add real examples
Sample request/response payloads are what make documentation actually usable, not just descriptive.
Cover errors, auth, and limits
The parts most often left out, and the ones API consumers hit first when something goes wrong.

Frequently asked questions
Why do examples matter more than a field-by-field description?
Most developers copy a working example and adapt it rather than reading a field list line by line — documentation without examples gets skipped or misused.
What should the errors section include?
Every distinct error code or status your API returns, plus what triggers it and how a consumer should respond — not just a generic "errors may occur" note.
Does this generate the final documentation itself?
It generates the prompt and completeness check; you'd still run it through your AI coding assistant to produce the final formatted docs.
How is completeness scored?
Each of the four sections is checked for at least 10 characters of real content; the score is the percentage of sections that pass.
How We Compare

Swagger/OpenAPI and Postman generate interactive documentation from a formal spec. This tool helps you gather the plain-language content — examples, errors, limits — before or alongside that formal spec.
