OpenCage

API

Forward & reverse geocoding with open data sources

Overview

OpenCage provides RESTful forward (address-to-coordinates) and reverse (coordinates-to-address) geocoding APIs leveraging open data like OpenStreetMap. Responses are JSON-formatted, including detailed location metadata (country, city, postal code, admin divisions). Ideal for mapping apps, delivery logistics, location-based marketing, or IoT devices needing geospatial context. Supports multi-language results, bounding box filters, and confidence scores to refine accuracy, with flexible rate limits for small projects and enterprises.

Example Integration (JavaScript)

script.js JS


fetch('https://opencagedata.com')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
