API文档生成器

生成结构化的API文档,包括端点描述、请求/响应示例、认证细节、错误代码和速率限制规范。

了解更多

The API Documentation Generator transforms your API information into polished, professional documentation that developers actually want to read. Supports REST, GraphQL, gRPC, and WebSocket APIs with multiple output formats including OpenAPI spec, Markdown, and HTML. Includes authentication setup guides, rate limiting details, versioning notes, and real-world request/response examples.

Expect clean code blocks with comments, plus a short explanation of what changed.

如何使用 API文档生成器

  1. Paste your API details — endpoint paths, methods, parameters, request/response bodies, or even raw code from your router/controller files.
  2. Select the API type (REST, GraphQL, gRPC, or WebSocket) for protocol-specific documentation patterns.
  3. Choose your authentication method so the docs include proper auth setup guides and code examples.
  4. Pick an output style — OpenAPI for machine-readable specs, Markdown for GitHub, or Developer Portal for a Stripe-style experience.

使用案例

1

Generate OpenAPI 3.0 specs from existing route definitions for Swagger UI

2

Create developer portal documentation for a public API launch

3

Document internal microservice APIs for team onboarding

4

Produce GraphQL schema documentation with query examples

5

Build WebSocket API docs with connection lifecycle and event catalogs

最佳结果的技巧

  • Include real field names and data types in your input — the generator produces much better docs when it knows your actual schema.
  • Paste your route definitions or controller code directly; the AI can extract endpoints, parameters, and response shapes automatically.
  • For OpenAPI output, the generated spec can be imported directly into Swagger UI, Redoc, or Stoplight for interactive documentation.
  • Always review generated error responses — add any domain-specific error codes your API returns.

常见问题

Can I paste my actual code instead of describing the API?

Yes. You can paste route definitions (Express, FastAPI, Spring Boot, etc.), controller files, or even database models. The generator will extract endpoint information, parameters, and response structures from your code.

Is the generated OpenAPI spec valid?

The generated OpenAPI 3.0 spec follows the official specification structure. You can validate it with the Swagger Editor or any OpenAPI linter. Minor adjustments may be needed for complex schemas.

How do I document WebSocket events?

Select 'WebSocket API' as the type. The generator will produce documentation covering connection setup, authentication handshake, event types (client-to-server and server-to-client), message formats, heartbeat/ping-pong, and reconnection strategies.

Does it support multiple authentication methods?

Select the primary authentication method from the dropdown. If your API supports multiple methods, mention the additional ones in your API description and the generator will document all of them.

Can I generate docs for a GraphQL API?

Yes. Select 'GraphQL API' as the type and provide your schema, queries, mutations, and subscriptions. The output will include type definitions, query examples, variable usage, and error handling patterns specific to GraphQL.

How detailed are the error response examples?

Each endpoint includes common HTTP error responses (400, 401, 403, 404, 422, 429, 500) with realistic JSON error bodies, error codes, and human-readable messages. A consolidated error reference table is also generated.
