API Reference Documentation Generator
Generate polished API docs from specs in minutes, not days
What You Can Do
Transform raw API specifications into professional, developer-friendly reference documentation. You provide your OpenAPI spec, raw endpoints, or API definition, and Claude generates complete endpoint documentation with consistent formatting, working code examples across multiple languages, comprehensive error catalogs, and integration guides. The result is publication-ready docs that developers can immediately understand and use.
Features
Claude generates complete descriptions, parameters, response schemas, and status codes for each endpoint with zero manual formatting.
Creates working examples in JavaScript, Python, cURL, Ruby, and Go so developers see exactly how to use each endpoint.
All endpoints follow the same template and visual hierarchy, making navigation intuitive and your documentation predictable.
Catalogs every error code with explanations, root causes, and solutions so developers troubleshoot independently.
Accepts OpenAPI 3.0 specs, Swagger 2.0 definitions, or raw endpoint lists and generates complete documentation automatically.
Generates ready-to-copy cURL commands, request payloads, and response examples for every endpoint you document.
Documents auth flows (OAuth, API keys, JWT, mutual TLS) with security best practices and implementation examples.
