Integration Guide

1

Review the API Documentation

Visit the official Kroki documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.

2

No Authentication Required

Good news — Kroki does not require any authentication. You can start making API requests directly without registering for an API key or setting up OAuth credentials.

3

Use HTTPS for Secure Requests

Kroki supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.

4

CORS Enabled — Direct Browser Access

Kroki has CORS enabled, meaning you can make requests directly from the browser. This is ideal for frontend-only applications built with React, Vue, or vanilla JavaScript.

5

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
// JavaScript example
fetch("https://kroki.io")
  .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 Kroki:", error);
  });

Python / Requests:

python
# Python example
import requests

response = requests.get("https://kroki.io")

if response.status_code == 200:
    data = response.json()
    print("API response:", data)
else:
    print(f"Error: {response.status_code}")
