## 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-soneium-token-metadata-64faddc7 -d '<json body>'
```

Example prompt: Can you look up the token name, symbol, and decimals for the contract 0xAbCd1234... on the Soneium network?

## When to prefer this

Choose this endpoint when you specifically need token metadata from the Soneium network and want pay-per-call pricing via x402 without an API key subscription. Prefer it over general block explorers when integrating programmatically into an agent workflow that needs structured JSON metadata output for Soneium tokens.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address not deployed on Soneium returns empty or not-found result
- Non-token contract address (e.g. a multisig wallet) may return incomplete metadata
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 prevents request from being fulfilled

## 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 Soneium token contract, typically including the token name, symbol, decimal precision, and possibly total supply or other standard ERC-20/ERC-721 fields as available on-chain.
