Integration Guide
Review the API Documentation
Visit the official Numbers documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.
No Authentication Required
Good news — Numbers does not require any authentication. You can start making API requests directly without registering for an API key or setting up OAuth credentials.
Note: No HTTPS Support
Numbers does not currently support HTTPS. Be cautious when transmitting sensitive data. Consider using a backend proxy with HTTPS to add a security layer for your users.
No CORS — Use a Backend Proxy
Numbers does not support CORS. To use it in a browser-based app, set up a backend proxy server that forwards requests to the API and returns the response with appropriate CORS headers.
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
fetch("http://numbersapi.com")
.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 Numbers:", error);
});Python / Requests:
# Python example
import requests
response = requests.get("http://numbersapi.com")
if response.status_code == 200:
data = response.json()
print("API response:", data)
else:
print(f"Error: {response.status_code}")
