## 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 erc-20-token-contract-name-lookup-74789279 -d '<json body>'
```

Example prompt: What's the name of the ERC-20 token contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you need to resolve a human-readable name for an ERC-20 token given only its contract address and chain, especially across multiple EVM chains including Base, Arbitrum, Optimism, Polygon, and others. Prefer this over on-chain RPC calls when you don't have direct node access or want a simple pay-per-call REST interface without managing Web3 infrastructure.

## Known failure modes

- Contract address not found or not an ERC-20 contract — returns error or empty name
- Unsupported chain enum value — validation error
- Invalid contract address format (not 0x + 40 hex chars) — schema validation failure
- Network node unavailable or timeout for the specified chain
- Contract exists but has no name function (non-standard ERC-20) — may return empty or error

## How this service works

Name of a token contract — Genesis402 / UnyKorn Operator Network

## Output
