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 on-chain metadata for the specified token contract, typically including the token name, symbol, and decimal precision as stored in the smart contract on the Katana network.
Example use cases
Identify unknown DeFi token
“I've got this contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Katana — can you tell me what token it is, its symbol, and how many decimals it uses?”
Validate token before swap
“Before I approve this swap, can you pull the on-chain metadata for contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Katana so I can confirm it's the right token?”
Enrich token list with on-chain data
“I'm building a token list and need the official name, symbol, and decimals for the contract 0x6B175474E89094C44Da98b954EedeAC495271d0F deployed on Katana — can you fetch that from the chain?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/katana/token/metadataWhen to prefer
Choose this endpoint when you need fast, pay-per-call token metadata resolution on the Katana network without managing your own RPC infrastructure. Ideal for agents that occasionally need token details without committing to a subscription-based provider. Best when the contract address is known and you need basic on-chain metadata (name, symbol, decimals) quickly and cheaply at $0.01 per call.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (e.g. a plain wallet or non-ERC20 contract) may return empty or null metadata
- Network congestion or RPC unavailability may cause timeouts
- Contract address on a different network (not Katana) will return incorrect or no results
- Missing contractAddress field in request body returns a validation error
