OpenCage Geocoder
Easy, Open, Worldwide, Affordable Geocoding and Geosearch
OpenCage Geocoder is a worldwide geocoding and geosearch API built on open data, primarily OpenStreetMap. It converts coordinates into place names and addresses, and place names into coordinates, returning structured results with components such as house numbers, roads, postcodes, towns, and countries. Responses can include additional data such as timezones, Wikidata identifiers, NUTS codes, FIPS codes, speed limits, UN/LOCODEs, and what3words, along with formatted address strings.
The service exposes a single API for forward and reverse geocoding, with results that can be cached and displayed on any map. SDKs and tutorials are available for more than 40 languages and frameworks, including Java, Perl, PHP, Python, Ruby, Node.js, Go, and curl. The API supports language-specific address formatting, result limits, and structured JSON output. OpenCage also offers a spreadsheet upload tool for batch geocoding, an Agent Skill for AI coding assistants, and documentation covering quick starts and best practices.
OpenCage is aimed at developers and organizations that need reliable geocoding without maintaining their own system, including use cases in logistics, fleet tracking, classifieds, academia, data enrichment, IoT, image processing, micromobility, and payment processing. A free trial tier provides a daily request allowance without requiring a credit card. Paid plans are subscription-based, with tiers defined by daily request limits, request-per-second rates, file sizes, API key counts, IP and CORS restrictions, and support levels; an Enterprise option offers custom limits, data formats, SLAs, and terms.
