## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability phantom-api-katana-token-metadata-91a9e84c -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the contract at 0x4200000000000000000000000000000000000006 on the Katana network?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
