- Keep body parameters business-focused and let preview build request examples.
- Compare export formats before delivery and pick one that matches team standards.
Guide
API Document Generator helps you define API metadata, endpoints, and parameters, then produce structured documentation outputs for consistent delivery.
Key Features
- Visual endpoint and parameter editing with generated request and response samples.
- Four export targets: Markdown, HTML, OpenAPI 3.0, and cURL snippets.
- Quick starter templates for REST, Blog, E-commerce, and Auth APIs.
- One-click copy and file download for wiki, repo, or QA handoff usage.
Format Notes
- Markdown: ideal for repository docs, internal wiki, and long-term knowledge records.
- HTML: ideal for direct static hosting and readable browser delivery.
- OpenAPI: ideal for gateways, mocks, testing platforms, and automation pipelines.
- cURL: ideal for integration debugging, issue reproduction, and test writing.
Use Cases
- Backend API design reviews and iterative version documentation
- Frontend-backend alignment before integration and contract checks
- QA preparation for endpoint coverage and regression planning
- Technical support handoff and implementation onboarding
FAQ
- Does it require network calls: no, generation and export run locally in your browser.
- Is endpoint count limited: no, add as many endpoints as your project needs.
- Can OpenAPI output be used directly: yes as a base file, then extend with security and schemas.
- Can I download files: yes, export uses an extension based on the current format.
