OpenCage API
Overview
OpenCage is a geocoding API that converts addresses into geographic coordinates (and vice versa) using open data sources including OpenStreetMap. It supports over 2,500 languages and scripts and provides very detailed address components in its responses. The free tier offers 2,500 requests per day, which is plenty for small projects.
Beginner Tip
Use the `countrycode` parameter to restrict results to a specific country (e.g., countrycode=de for Germany) — this dramatically improves accuracy when you know where the address is. Always URL-encode your query string.

const url = "https://opencagedata.com/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"X-API-Key": "YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
