## 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 x402-silverbackdefi-app-f53e6337 -d '<json body>'
```

Example prompt: What are the name, symbol, decimals, and total supply for the Ethereum token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?

## When to prefer this

Use this endpoint when you need on-chain Ethereum token metadata (name, symbol, decimals, supply) for a known contract address, especially in DeFi workflows where token identification or normalization is needed before swapping, pricing, or displaying token information.

## Known failure modes

- Invalid or malformed contract address returns an error
- Non-existent contract address returns not found
- Non-token contract address (e.g. a plain wallet) returns no metadata
- Network connectivity issues cause timeouts
- Rate limiting or payment failure returns 402

## Output

Returns structured metadata about the specified Ethereum token including its name, symbol, number of decimals, total supply, and other on-chain contract details.
