Understand Any API Request Instantly
Request Explainer
Paste a cURL or fetch snippet.
Your plain-English explanation will appear here.
Whether you're debugging unfamiliar code or learning a new API from documentation, deciphering complex API requests can be a challenge. Our Free AI API Request Explainer takes any cURL command or JavaScript `fetch` snippet and translates it into a clear, human-readable explanation, so you can understand what's happening under the hood in seconds.
What is the API Request Explainer?
This tool is a developer's best friend for working with APIs. You paste a snippet of code that makes an HTTP request, and our Gemini-powered tool breaks it down component by component. It tells you the purpose of the request, explains the endpoint, identifies the HTTP method, and details every header and piece of data in the payload. It's like having a senior developer looking over your shoulder and explaining the code to you.
How It Works: AI-Powered Code Comprehension
The tool leverages the Gemini AI's advanced code understanding capabilities. When you submit a snippet, the AI performs a systematic breakdown:
- Identifies the Request Type: It first recognizes whether the snippet is a command-line `cURL` request, a JavaScript `fetch` call, or another common HTTP client.
- Parses the URL: It extracts the base URL and the specific endpoint being called, explaining the likely purpose of that endpoint based on RESTful conventions.
- Explains the Method: It identifies the HTTP method (GET, POST, PUT, DELETE, etc.) and explains its function in simple terms (e.g., "POST is used to create a new resource on the server").
- Details the Headers: It iterates through the request headers (e.g., `Content-Type`, `Authorization`) and explains the role of each one. For authorization headers, it identifies the authentication type (e.g., "Bearer Token," "Basic Auth").
- Analyzes the Body/Payload: If the request includes a body (common in POST/PUT requests), it parses the data (e.g., JSON) and explains the meaning of each key-value pair.
Who Is This For?
For Junior Developers & Students
Accelerate your learning curve. When you encounter a complex API call in a tutorial or codebase, use this tool to get a clear explanation. It's a powerful way to build a deeper understanding of how web services communicate.
For Senior Developers & API Designers
Quickly understand third-party API documentation or debug a colleague's code. Use it to double-check your own API calls for correctness or to generate plain-English explanations for your technical documentation.

Frequently Asked Questions
What types of API requests can this tool explain?
Our tool can explain REST API requests (GET, POST, PUT, DELETE), GraphQL queries, webhook configurations, and various authentication methods including OAuth, API keys, and JWT tokens.
How does the tool help with API debugging?
It analyzes your request structure, identifies potential issues like missing headers, incorrect endpoints, malformed JSON, and suggests fixes. It also explains expected response formats and common error codes.
Can I use this for third-party APIs?
Yes, the tool works with any API. Paste your request details and it will explain the structure, parameters, and expected behavior regardless of whether it's a public API or your own custom endpoint.
Does it help with API documentation?
Absolutely. The tool generates clear explanations that you can use in your API documentation, including parameter descriptions, example requests/responses, and usage notes.
What information should I provide for the best explanation?
Include the HTTP method, endpoint URL, headers, request body (if applicable), and any authentication details. The more context you provide, the more detailed and helpful the explanation will be.
Is this tool suitable for beginners?
Yes, it's designed to help developers at all levels. Beginners get clear explanations of API concepts, while experienced developers can use it for quick debugging and documentation.
