Common Use Cases

1. Verifying NFT ownership before allowing actions.
2. Checking token balances for wallet displays.
3. Validating fractional ownership (ERC-1155).
4. Building allow lists based on token holdings.

Best Practices

• Always include at least owner and contract arguments.
• For ERC-1155 tokens, check the value field for quantity owned.
• Combine with contractType filter when you only need specific token standards.
• Returns null when no matching balance is found.
• Returns an error if required arguments (owner, contract) are missing.
• May return partial data if metadata is unavailable.
