# API Tools

## Overview

Tools and techniques for API development, testing, documentation, and debugging.

---

## HTTP Clients

### cURL

```bash
# Basic GET
curl https://api.example.com/users

# GET with headers
curl -H "Authorization: Bearer TOKEN" \
     -H "Accept: application/json" \
     https://api.example.com/users

# POST with JSON body
curl -X POST \
     -H "Content-Type: application/json" \
     -d '{"name": "John", "email": "[email protected]"}' \
     https://api.example.com/users

# POST with form data
curl -X POST \
     -F "[email protected]" \
     -F "name=My Document" \
     https://api.example.com/upload

# PUT request
curl -X PUT \
     -H "Content-Type: application/json" \
     -d '{"name": "Updated Name"}' \
     https://api.example.com/users/123

# DELETE request
curl -X DELETE https://api.example.com/users/123

# Show response headers
curl -i https://api.example.com/users

# Verbose output (debugging)
curl -v https://api.example.com/users

# Follow redirects
curl -L https://example.com/redirect

# Save response to file
curl -o response.json https://api.example.com/users

# With authentication
curl -u username:password https://api.example.com/protected
curl --oauth2-bearer TOKEN https://api.example.com/protected

# Measure timing
curl -w "@curl-format.txt" -o /dev/null -s https://api.example.com
```

```txt
# curl-format.txt
     time_namelookup:  %{time_namelookup}s\n
        time_connect:  %{time_connect}s\n
     time_appconnect:  %{time_appconnect}s\n
    time_pretransfer:  %{time_pretransfer}s\n
       time_redirect:  %{time_redirect}s\n
  time_starttransfer:  %{time_starttransfer}s\n
                     ----------\n
          time_total:  %{time_total}s\n
```

### HTTPie

```bash
# GET request (more readable output)
http https://api.example.com/users

# With headers
http https://api.example.com/users \
  Authorization:"Bearer TOKEN" \
  Accept:application/json

# POST with JSON (default)
http POST https://api.example.com/users \
  name=John \
  [email protected]

# POST with raw JSON
http POST https://api.example.com/users \
  < user.json

# Form data
http -f POST https://api.example.com/login \
  username=john \
  password=secret

# File upload
http -f POST https://api.example.com/upload \
  [email protected]

# Download file
http --download https://api.example.com/files/document.pdf

# Session persistence
http --session=user-session POST https://api.example.com/login
http --session=user-session GET https://api.example.com/profile

# Only headers
http --headers https://api.example.com/users

# Only body
http --body https://api.example.com/users
```

### Generate Client SDK

```bash
# Generate TypeScript client
npx openapi-generator-cli generate \
  -i openapi.yaml \
  -g typescript-fetch \
  -o ./generated/client

# Generate Python client
openapi-generator generate \
  -i openapi.yaml \
  -g python \
  -o ./generated/python-client
```

---

## Mock Servers

### Prism (OpenAPI Mock Server)

```bash
# Start mock server
npx @stoplight/prism-cli mock openapi.yaml

# With dynamic responses
npx @stoplight/prism-cli mock openapi.yaml --dynamic

# Custom port
npx @stoplight/prism-cli mock openapi.yaml -p 4010
```

### JSON Server (Quick REST API)

```json
// db.json
{
  "users": [
    { "id": 1, "name": "John", "email": "[email protected]" },
    { "id": 2, "name": "Jane", "email": "[email protected]" }
  ],
  "posts": [
    { "id": 1, "title": "Hello World", "userId": 1 }
  ]
}
```

```bash
# Start server
npx json-server --watch db.json --port 3001

# Routes automatically created:
# GET    /users
# GET    /users/1
# POST   /users
# PUT    /users/1
# DELETE /users/1
# GET    /posts?userId=1
```

---

## API Debugging

### Request/Response Logging

```typescript
import axios from 'axios';

// Request interceptor
axios.interceptors.request.use((config) => {
  console.log('Request:', {
    method: config.method?.toUpperCase(),
    url: config.url,
    params: config.params,
    data: config.data,
    headers: config.headers,
  });
  return config;
});

// Response interceptor
axios.interceptors.response.use(
  (response) => {
    console.log('Response:', {
      status: response.status,
      headers: response.headers,
      data: response.data,
    });
    return response;
  },
  (error) => {
    console.log('Error:', {
      status: error.response?.status,
      data: error.response?.data,
    });
    return Promise.reject(error);
  }
);
```
