# Etherscan API

Pull an account's history and a contract's source into C#

## What this does

Some things are easier to ask a block explorer than to work out from a node: what an account has done, what gas costs right now, what a contract's verified source actually says. This queries Etherscan for that from your .NET code. Reach for it when you need history or contract details rather than live chain calls.

### Top 3 things it does for you

- List an account's transactions
- Check an address balance
- Look up token transfers for an address

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 Etherscan API safe to install?

AIR scanned this exact version of Etherscan 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/etherscan-api.

### How do I install Etherscan API?

Open https://airmarket.ai/app/etherscan-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/etherscan-api. Install from that link, not the branch.
