## 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-token-metadata-lookup-d4b626e3 -d '<json body>'
```

Example prompt: Can you look up the on-chain metadata — name, symbol, and decimals — for the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call on-chain token metadata retrieval without managing your own RPC infrastructure. Ideal for agents that need to resolve contract addresses to human-readable token information across many EVM-compatible chains without committing to a subscription.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address exists but is not a token contract (e.g. a plain wallet or non-ERC-20 contract) may return empty or null metadata
- Unsupported network or chain for the given contract address
- Rate limiting or payment failure due to missing or invalid x402 payment header
- Network congestion causing slow or failed RPC response

## 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 structured on-chain metadata for the specified token contract, typically including the token name, symbol, and decimal precision as recorded on the blockchain.
