Integration Guide
Review the API Documentation
Visit the official Code.gov documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.
Obtain an API Key
Code.gov requires an API key for authentication. Register on the provider's website to get your unique key. Keep it secure and never expose it in client-side code — use environment variables or a backend proxy.
Use HTTPS for Secure Requests
Code.gov supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.
CORS Status Unknown — Test Before Use
The CORS status for Code.gov is unknown. Test with a simple browser-based request to verify. If CORS is not supported, set up a backend proxy to handle requests server-side.
Implement and Test
Write your API integration code, start with a simple test request to verify connectivity. Implement proper error handling for network failures, rate limits, and invalid responses. Monitor your API usage to stay within any limits.
Code Examples
JavaScript / Fetch API:
// JavaScript example (with API key)
const apiKey = process.env.API_KEY; // Store your key securely
fetch("https://code.gov", {
headers: {
"Authorization": `Bearer ${apiKey}`,
// Or use: "X-API-Key": apiKey
// Check the docs for the correct header format
}
})
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
return response.json();
})
.then(data => {
console.log("API response:", data);
})
.catch(error => {
console.error("Error fetching from Code.gov:", error);
});Python / Requests:
# Python example (with API key)
import requests
import os
api_key = os.environ.get("API_KEY") # Store your key securely
headers = {
"Authorization": f"Bearer {api_key}",
# Or use: "X-API-Key": api_key
}
response = requests.get("https://code.gov", headers=headers)
if response.status_code == 200:
data = response.json()
print("API response:", data)
else:
print(f"Error: {response.status_code}")
