How do I check the balance of a specific wallet address?

You can use the `get_address_summary` tool by providing the chain name (e.g., 'eth') and the address. For a detailed list of all token holdings, use the `get_token_balance` tool.

Can I retrieve information about NFT collections?

Yes! Use the `get_nft_collection_info` tool with the chain name and the NFT contract address to fetch metadata and collection details.

How do I find the latest block on a specific blockchain?

Simply use the `get_latest_block` tool and specify the chain (e.g., 'btc', 'eth', 'polygon'). It will return the height and details of the most recently mined block.
