What makes good API documentation?

Accurate (matches actual API), complete (all endpoints), clear (good examples), up-to-date, easy to navigate, interactive where possible. Developer feedback helps identify gaps.

Should documentation be generated or written?

Both. Generate reference docs from OpenAPI spec (accuracy). Write guides and tutorials manually (context). Combine for comprehensive coverage.

How do I keep documentation up to date?

Generate from spec (auto-updates with API changes). Include doc updates in code review. Test documentation examples. Monitor for drift. Treat docs as code.

What languages should code samples cover?

At minimum: curl (universal), and 1-2 popular languages for your audience. Common: JavaScript, Python, Ruby, Java. SDKs in popular languages provide best experience.
