# coingecko

[CoinGecko](https://www.coingecko.com/) provides cryptocurrency market data, token metadata, exchange information, derivatives data, trending assets, categories, and NFT collection data.

In Agent Forge, the CoinGecko integration allows workflows to pull live and historical market intelligence into agents. Use it for crypto dashboards, token research agents, market monitoring, price alerts, asset comparison, and automated research pipelines.

## Usage Instructions
