## 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-worldchain-token-metadata-3ef98671 -d '<json body>'
```

Example prompt: Can you look up the token metadata — name, symbol, and decimals — for the Worldchain contract at 0x1234abcd...efgh?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call token metadata lookups specifically on the Worldchain network without managing your own RPC infrastructure. Ideal for agents enriching transaction data, building DeFi dashboards, or validating token contracts on Worldchain at $0.01 per call with no subscription required.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address does not exist on Worldchain returns not-found error
- Contract exists but is not a token contract (no metadata methods) returns empty or error
- Network congestion may slow response
- Payment failure via x402 prevents request from being processed

## 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 token metadata for the specified Worldchain contract address, typically including the token name, symbol, number of decimals, and potentially other ERC-20 standard fields stored in the contract.
