# CoinGecko API

Look up what a token is and what it costs, from C#

## What this does

You have a token address, or a coin's name on CoinGecko, and you need its price or its details inside your .NET code. This fetches that from CoinGecko: prices, metadata, token lists, and the mapping between chains and CoinGecko's own platform names. Reach for it when your app needs to show or use token prices.

### Top 3 things it does for you

- Get a token's price by its contract address
- Pull token metadata for a coin
- Match a chain to its CoinGecko asset platform

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is CoinGecko API safe to install?

AIR scanned this exact version of CoinGecko API and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 1d68d2b03605, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/coingecko-api.

### How do I install CoinGecko API?

Open https://airmarket.ai/app/coingecko-api on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/Nethereum/Nethereum/tree/1d68d2b036054226a11179eb1d1bda57f30a5365/plugins/nethereum-skills/skills/coingecko-api. Install from that link, not the branch.
