## 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 hunter-address-api-erc-20-token-metadata-acbb8091 -d '<json body>'
```

Example prompt: What's the token name, symbol, decimals, and total supply for the ERC-20 contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Use this endpoint when you need fast, read-only ERC-20 token metadata (name, symbol, decimals, total supply) for a known contract address on the Base network. Prefer this over a full due-diligence report when you only need basic token facts without proxy/upgradeability analysis. Ideal for enriching token lists, validating addresses before transactions, or displaying token info in a UI.

## Known failure modes

- Address is not a valid ERC-20 contract on Base — returns error or empty metadata
- Malformed 0x address input — validation error returned
- Contract exists but does not implement standard ERC-20 metadata (name/symbol/decimals) — partial or null fields
- Base RPC node temporarily unavailable — timeout or service error
- Contract is a proxy and metadata may reflect the proxy rather than the implementation

## How this service works

On-chain ERC-20 token metadata for any Base contract: symbol, name, decimals, total supply, explorer link

## Output

Returns a structured object containing the ERC-20 token's on-chain metadata: human-readable name, ticker symbol, decimal precision, total token supply, and a link to the Base block explorer page for the contract.
