opencage-skills

Agent skills for working with OpenCage geocoding and geosearch services. These skills give any AI coding agent the context it needs to integrate with the OpenCage APIs correctly — including endpoint details, SDK usage patterns, error handling, and common pitfalls.

The skills are plain markdown files that work with any agent that can read documentation. First-class installation is provided for Claude Code via its plugin system.

references/java.md	Java SDK usage
references/perl.md	Perl SDK usage
references/commandline.md	Command-line batch CSV processing

Geosearch skill

Use when you need geographic place autosuggest or autocomplete on a web page, or are integrating a location search widget with Leaflet, OpenLayers, or MapLibre.

Prerequisites

• An OpenCage account with the appropriate API key(s):
