Code Examples:

cURL:

curl -X GET "https://api.example.com/v1/resource/123" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json"

JavaScript:

const response = await fetch('https://api.example.com/v1/resource/123', {
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  }
});
const data = await response.json();

Python:

import requests

response = requests.get(
    'https://api.example.com/v1/resource/123',
    headers={'Authorization': 'Bearer YOUR_API_KEY'}
)
data = response.json()

Go:

req, _ := http.NewRequest("GET", "https://api.example.com/v1/resource/123", nil)
req.Header.Set("Authorization", "Bearer YOUR_API_KEY")
resp, _ := client.Do(req)

Data Models

Document shared data structures:

Model Name

{
  "field1": "string",
  "field2": 123,
  "nested": {
    "field3": true
  }
}

Fields:

• •field1 (string, required): Description
• •field2 (integer, optional): Description
• •nested.field3 (boolean, required): Description

Error Handling

Error Response Format:

{
