CoinGecko SKILL is an installable package that gives AI agents built-in knowledge of the CoinGecko API — endpoints, parameters, and common workflows — so your agent can write accurate queries and code without manual prompting. Works with Claude Code, Gemini CLI, Codex CLI, and other SKILL-compatible agents. Setup takes under 3 minutes.

​
Installation

Install the SKILL for agents like Claude Code, Gemini CLI, or Codex CLI.

​
Via skills.sh

1

Install the skills package

npm install -g skills
See npmjs/skills for details.
2

Install the CoinGecko SKILL

npx skills add coingecko/skills -g -y
-g installs globally for all agents.

​
Via GitHub

1

Clone the repository

git clone https://github.com/coingecko/skills.git coingecko-skills
2

Move to your agent's SKILLs directory

mv coingecko-skills ~/.claude/skills/coingecko
Path varies by agent and OS. Example above is for Claude Code on Mac/Linux.
For the best experience — especially on the Claude free plan — set up the CoinGecko MCP Server alongside the SKILL.

​
Try It Out

Once installed, try asking your agent:
  • “If I invested $100 in Bitcoin back in December 2018, how much would it be worth today?”
  • “What was the ATH of XPL?”
  • “What is the current market cap of DZnQi17HFgSM8mJ4nhVicz32B97XyTsd6MUVuDJgP9Jo from Solana?”
  • “What are the top NFT collections this week?”
