How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a list of token balances associated with the specified owner address on the Katana network, broken down by contract address — including token amounts and potentially metadata such as token name, symbol, and decimals.
Example use cases
DeFi portfolio snapshot
“Show me all the token balances held by wallet 0xDeFiUser123... on Katana — I want to see everything it holds across my tracked contracts 0xTokenA... and 0xTokenB....”
Verify airdrop token receipt
“Did wallet 0xRecipient456... actually receive the airdrop tokens from contract 0xAirdropToken789... on Katana? Check the current balance for me.”
Monitor whale wallet holdings
“What's the current balance of the stablecoin at contract 0xUSDC... and the governance token at 0xGOV... for the whale wallet 0xWhale999... on the Katana chain?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/katana/token/balancesWhen to prefer
Choose this endpoint when you need fast, pay-per-call token balance lookups specifically on the Katana network without managing your own RPC node or indexer. It's ideal for lightweight agents that need on-demand balance checks rather than streaming or batch historical queries, and when cost efficiency at $0.01/call is important.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Non-existent contract addresses may return zero balances or errors
- Network congestion or node unavailability may cause timeouts
- Payment failure via x402 protocol results in 402 response before data is returned
- Unsupported contract address format may cause parsing errors
