REST Endpoint Documenter - Markdown Doc Generator

Document a REST endpoint quickly by entering the URL, method, headers, and sample request/response. Generates formatted Markdown documentation and an example cURL command instantly.

Presets:

Endpoint Details

# List all items with pagination

## Endpoint

**Method:** `GET`
**URL:** `https://api.example.com/v1/items`

## Authentication

```
X-API-Key: sk_live_abc124
```

## Query Parameters

| Parameter | Example Value |
|-----------|---------------|
| `page` | 1 |
| `per_page` | 20 |
| `sort` | created_at |

## Request Headers

| Header | Value |
|--------|-------|
| `X-API-Key` | `sk_live_abc124` |

## Response

**Status:** `200 OK`

```json
{
  "data": [

  ],
  "total": 2
}
```

REST Endpoint Documenter: Generate API Markdown Docs and cURL Commands

Writing API documentation is often skipped under time pressure, but undocumented endpoints become a maintenance burden. Our documenter eliminates the friction — fill in the endpoint details and get formatted Markdown documentation and a ready-to-run cURL command in seconds.

The generated Markdown works in GitHub README files, Confluence, Notion, GitLab wikis, and any other Markdown-compatible documentation platform.

Formula
Markdown structure: # Endpoint Description ## Endpoint (Method + URL) ## Authentication ## Query Parameters (table) ## Request Headers (table) ## Request Body (JSON code block) ## Response (status + body)

REST API Documentation Best Practices

Every endpoint should document:
1. HTTP method and full URL pattern
2. Authentication requirements
3. All query parameters with types and defaults
4. Request body schema with example
5. All possible response codes
6. Response body schema with example
7. Rate limiting behavior
8. Error response format

Good docs reduce support burden and increase API adoption.

cURL Command Guide

The generated cURL includes:
-X METHOD: HTTP method (POST, PUT, etc.)
-H 'Header: Value': Request headers including auth
-d 'body': Request body for POST/PUT/PATCH
?key=value: Query parameters appended to URL

Test the endpoint immediately: paste the cURL command in your terminal. Add -v for verbose output to see all request and response headers.

Practical Examples

Create User endpoint

  • 1.Method: POST, Auth: Bearer Token
  • 2.Headers: Content-Type: application/json
  • 3.Body: JSON with name, email, role fields
  • 4.Response: 201 Created with user object

Paginated list endpoint

  • 1.Method: GET, Auth: API Key
  • 2.Params: page, per_page, sort, filter
  • 3.Response: 200 OK with data array + total
  • 4.Copy Markdown into README or API docs

Frequently Asked Questions

What does this REST Endpoint Documenter generate?

It generates two outputs: Markdown documentation (ready to paste into README, Wiki, or Notion) containing the method, URL, auth type, query parameters, request headers, request body, and response body; and a cURL command for immediate testing of the endpoint from the command line.

What authentication types are supported?

No Auth (public endpoints), Bearer Token (generates Authorization: Bearer header), API Key (generates X-API-Key header), and Basic Auth (generates Authorization: Basic header). The auth credentials are automatically included in both the Markdown and cURL outputs.

Can I document multiple endpoints?

This tool documents one endpoint at a time. Use the presets (Create User, List Items, Update Resource, Delete Resource) to quickly configure common patterns, then copy the generated Markdown for each endpoint and assemble them into a single API documentation file.

What is the cURL output format?

The cURL command includes the HTTP method (-X), URL with query parameters appended, all authentication headers, custom request headers, and the request body (-d flag for POST/PUT/PATCH). It uses multi-line format with backslash continuation for readability.

Can I use path parameters like :id or {id}?

Yes. Enter the URL with path parameters as you would in your API definition: https://api.example.com/v1/items/:id or .../items/{id}. The documentation will include the URL exactly as entered, making path parameters visible to API consumers.

What format should the request and response body be in?

Enter the bodies as valid JSON. The generator wraps them in a JSON code block in Markdown. You can also enter any other format (XML, plain text, form data) - it will be displayed as-is in a code block.

How do I document multiple response scenarios?

Currently the form supports one response. For multiple scenarios (success + error), generate docs for each status code separately and combine the Markdown. Common practice is to document the success response in detail and list error codes in a table.

Can I use this to generate OpenAPI/Swagger specs?

This tool generates Markdown, not OpenAPI YAML/JSON. For OpenAPI spec generation, you would need a dedicated tool. However, the structured Markdown output can serve as source material for manually creating OpenAPI specs, or as human-readable documentation alongside machine-readable specs.
