Can I query any specific subgraph if I have its ID?

Yes! Use the `query_subgraph` tool by providing the `subgraph_id` and your GraphQL `query` string. This allows for deep, custom data extraction beyond the standard tools.

Does this server support Solana token data?

Absolutely. You can use `get_svm_transfers`, `get_svm_holders`, and `get_svm_swaps` to interact with SPL tokens and decentralized exchanges on the Solana network.

Can I track historical balance changes for a specific wallet?

Yes, the `get_evm_historical_balances` tool provides historical balance data in OHLCV format for EVM chains, making it easy to analyze portfolio trends.
