## 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 arc-erc-20-token-metadata-lookup-3d67a502
```

Example prompt: What are the name, symbol, decimals, and total supply of the ERC-20 token at contract address 0x70857041Fef0CED97F9e01E7Ccc21889AFe3F6F4 on Arc?

## When to prefer this

Use this endpoint when you need on-chain ERC-20 token metadata (name, symbol, decimals, total supply) for a contract on the Arc network specifically. Prefer this over generic Ethereum or multi-chain token APIs when operating within the Arc ecosystem. Particularly useful for enriching transfer or balance data with human-readable token identifiers.

## Known failure modes

- Invalid or malformed contract address returns a 400 error
- Address is a non-ERC-20 contract (e.g. a wallet or non-standard contract) — may return empty/null fields or an error
- Contract not deployed on Arc network returns a not-found or empty response
- Network congestion or RPC issues may cause timeouts
- Missing required 'address' query parameter returns a 400 validation error

## How this service works

Name, symbol, decimals and total supply of any ERC-20 on Arc, read from the contract at the latest block.

## Output

Returns the token's full name (e.g. 'USD Coin'), ticker symbol (e.g. 'USDC'), number of decimals (e.g. 6), and total supply as a big integer, all read directly from the contract at the latest block on Arc.
