## 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 allium-chain-address-36cc661e -d '<json body>'
```

Example prompt: What token is at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum? I need the name, symbol, and decimals.

## When to prefer this

Use this endpoint when you have a specific token contract address and want to resolve it to known token metadata (name, symbol, decimals) on a given chain. Prefer this over listing all tokens when you already have the contract address and just need to identify or enrich it.

## Known failure modes

- Contract address not found in Allium's token registry — returns empty or not-found response
- Invalid or malformed contract address — returns validation error
- Unsupported chain name — returns error indicating chain is not supported
- Address exists but is not a token contract — returns no results
- Rate limit exceeded — returns 429 error

## How this service works

Look up tokens by chain and address

## Output

Returns token metadata including name, symbol, decimals, and other on-chain details for the specified contract address on the given blockchain network.
