We are pleased to present the comprehensive API Documentation for the Product Catalog Management API. This documentation provides detailed information on how to integrate with our services, manage product data, and leverage our platform's capabilities.
* 6.1. Get All Products (GET /products)
* 6.2. Get Product by ID (GET /products/{productId})
* 6.3. Create New Product (POST /products)
* 6.4. Update Product (PUT /products/{productId})
* 6.5. Delete Product (DELETE /products/{productId})
* 7.1. Product Object
* 7.2. Error Object
The Product Catalog Management API provides a robust and flexible way to programmatically manage your product catalog. With this API, you can list, retrieve, create, update, and delete product information, including details like name, description, price, and category. This documentation will guide you through the process of integrating your applications with our API.
All API requests should be made to the following base URL:
https://api.yourcompany.com/v1
The Product Catalog Management API uses API Keys for authentication. To authenticate your requests, you must include your API Key in the X-API-Key header for every request.
Example:
*Refer to the [Error Object](#72-error-object) data model for more details.*
### 5. Rate Limiting
To ensure fair usage and maintain API performance, requests are subject to rate limiting.
* **Limit:** 100 requests per minute per API Key.
* **Exceeding the limit:** If you exceed the rate limit, the API will return a `429 Too Many Requests` HTTP status code.
We recommend implementing retry logic with exponential backoff for your API calls to gracefully handle rate limit excursions and temporary network issues.
### 6. Endpoints
#### 6.1. Get All Products (`GET /products`)
Retrieves a list of all products in the catalog.
* **Method:** `GET`
* **Path:** `/products`
* **Description:** Returns a paginated list of product objects.
* **Query Parameters:**
* `limit` (optional, integer): Maximum number of products to return per page. Default is 20, max is 100.
* `offset` (optional, integer): Number of products to skip before starting to return results. Default is 0.
* `category` (optional, string): Filter products by category name.
* **Responses:**
* `200 OK`: A list of product objects.
This document outlines the detailed architecture plan for the "API Documentation Generator," a system designed to produce professional, comprehensive API documentation. This plan focuses on the core components, input/output mechanisms, feature implementation strategies, and underlying principles to ensure a robust, scalable, and user-friendly solution.
The primary goal of the API Documentation Generator is to automate the creation of high-quality, interactive API documentation. This solution aims to reduce manual effort, ensure consistency, and provide a superior experience for API consumers by delivering clear endpoint descriptions, practical request/response examples, precise authentication guides, and actionable SDK usage snippets.
Key Objectives:
The architecture will adhere to the following principles:
The API Documentation Generator will consist of several interconnected modules, each responsible for a specific phase of the documentation generation process:
This module is responsible for ingesting API definitions from various sources and converting them into a standardized internal representation.
* OpenAPI/Swagger Parser: Handles YAML and JSON files conforming to OpenAPI Specification (OAS) versions 2.0 and 3.x.
* RAML Parser: Processes RAML (RESTful API Modeling Language) definitions.
* API Blueprint Parser: Supports API Blueprint markdown-based definitions.
* Code Annotation Scanner (Optional/Future): Scans source code (e.g., JSDoc, PHPDoc, GoDoc annotations) to extract API metadata.
* Validate input schema against respective specifications.
* Parse and extract all relevant API metadata: endpoints, methods, parameters, request bodies, responses, security schemes, tags, descriptions.
A central, language-agnostic data structure that holds the parsed API information in a standardized, normalized format. This decouples the input parsers from the output renderers.
* API Metadata (title, version, description, base URL)
* Endpoint Objects (path, method, summary, description, tags)
* Parameter Objects (name, in, type, required, schema, description)
* Request Body Objects (content types, schema, examples)
* Response Objects (status codes, content types, schema, examples)
* Schema Definitions (reusable data structures)
* Security Scheme Definitions (type, description, flow)
* Server Definitions
* External Documentation Links
This module enriches the IR with additional data, processes specific documentation requirements, and prepares the data for rendering.
* Example Generator: Automatically generates realistic request/response examples based on defined schemas (e.g., using Faker libraries for data types, or extracting provided examples).
* Authentication Guide Generator: Interprets security scheme definitions from the IR and generates standardized instructions for various authentication types (API Key, OAuth2, Bearer Token).
* SDK Snippet Generator: Creates language-specific code examples (cURL, Python, JavaScript, Ruby, PHP, Java, etc.) for each endpoint, demonstrating how to make requests, including authentication.
* Markdown/HTML Processor: Converts any embedded Markdown in descriptions into the desired output format's equivalent.
* Cross-referencer: Resolves internal links and references within the documentation (e.g., linking to schema definitions from endpoint parameters).
This is the core of the documentation generation, using the enriched IR to populate predefined templates for various output formats.
* Template Engine: A robust templating system (e.g., Jinja2, Handlebars.js, Liquid) capable of iterating over the IR and inserting data.
* Theming/Styling Engine: Manages CSS, JavaScript, and other assets for different documentation themes.
* Interactive Components: Integrates elements like "Try It Out" buttons, syntax highlighting, collapsible sections, and search functionality.
Responsible for finalizing and delivering the generated documentation in the specified format(s).
* Static Site Generator Integration: Publishes documentation as a static website (HTML, CSS, JS).
* Markdown/PDF Exporter: Converts documentation into plain Markdown files or generates PDF documents.
* Version Control Integrator: Optionally pushes generated documentation to a Git repository (e.g., GitHub Pages).
The generator will prioritize industry-standard API description formats:
* Versions: 2.0, 3.0.x, 3.1.x
* File Formats: JSON, YAML
* Versions: 0.8, 1.0
* Latest stable version
The generator will support multiple output formats to cater to diverse needs:
* A fully navigable, searchable, and interactive static website.
* Features: "Try It Out" console, syntax highlighting, dark mode, responsive design.
* Theming: Customizable themes, logos, color schemes, and CSS.
* Generates a collection of Markdown files, suitable for integration into existing documentation platforms (e.g., GitBook, Docusaurus).
* Print-ready PDF documents for offline consumption.

fetch API, Axios (client-side)The typical workflow for generating documentation will be as follows:
openapi.yaml) and configuration (e.g., output format, theme).As part of the "API Documentation Generator" workflow, this step focuses on generating the core technical documentation in a machine-readable, industry-standard format, along with practical code examples for interaction.
The output below provides a comprehensive OpenAPI 3.0 Specification (YAML) for a hypothetical E-commerce Product API. This specification serves as the definitive contract for your API, detailing every endpoint, parameter, request/response structure, and authentication mechanism. It is the foundation for generating interactive documentation (e.g., Swagger UI), client SDKs in various languages, and server stubs.
Additionally, we provide well-commented, production-ready code examples demonstrating how to interact with an API defined by this specification, covering basic requests, authentication, and simulating SDK usage.
