From the project READMESDK Balance Queries
Query multi-chain token balances and portfolio data using natural language prompts.
Operations
| Operation | Example Prompt | Notes |
|---|---|---|
| Single token balance | "How much USDC do I have?" | Fastest query type |
| Multi-token balance | "Show my ETH, USDC, and DEGEN balances" | Single chain |
| All tokens on chain | "What tokens do I have on Base?" | Lists all holdings |
| Multi-chain balances | "Show my balances across all chains" | Slower, queries all |
| Portfolio value | "What's my total portfolio value in USD?" | USD conversion |
| Token value | "How much is my DEGEN worth?" | Single token USD |
| NFT holdings | "Show me my NFT collections" | Lists collections |
| NFT floor prices | "What's the floor price of my NFTs?" | External API calls |
Prompt Patterns
# Token Balances
"What are my token balances?"
"How much [TOKEN] do I have?"
"Show my [TOKEN] balance on [CHAIN]"
"What's my balance of token 0x..."
# Multi-Chain
"Show my balances across all chains"
"What are my balances on Base and Ethereum?"
"Compare my USDC holdings across all chains"
# Portfolio Value
"What's my total portfolio value in USD?"
"How much is my [TOKEN] worth in USD?"
"What's the total value of my Base holdings?"
# NFTs
"Show me my NFT collections"
"How many Pudgy Penguins do I own?"
"What's the floor price of my NFTs?"
Usage
import { BankrClient } from "@bankr/sdk";
const client = new BankrClient({
privateKey: process.env.BANKR_PRIVATE_KEY as `0x${string}`,
});
const result = await client.promptAndWait({
prompt: "What are my token balances on Base?",
});
console.log(result.response);
// "You have 150.5 USDC, 0.25 ETH, 1000 DEGEN on Base..."
Supported Chains
| Chain | Notes |
|---|---|
| Base | Default chain, fastest responses |
| Ethereum | Mainnet ERC20 and NFTs |
| Polygon | L2 tokens and NFTs |
| Solana | SPL tokens and NFTs |
Specify chain in prompt: "on Base", "on Ethereum", "on Polygon", "on Solana"
