## 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 api-barvis-io-cf9934b1
```

Example prompt: Can you look up the token details for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me its name, symbol, and any other info?

## When to prefer this

Use this endpoint when you need to resolve a raw blockchain token contract address into human-readable token metadata (name, symbol, decimals). Prefer this over general blockchain explorers when you need a simple, paid API call with consistent structured output suitable for agent workflows.

## Known failure modes

- Invalid or malformed contract address returns an error
- Address not found on supported chain returns empty or 404
- Non-token contract address (e.g. EOA or non-standard contract) may return no results
- Network or chain not supported may return an error
- Payment of 0.1 USDC required per call via x402 protocol; missing payment returns 402

## Output

Returns metadata and details about the blockchain token associated with the provided contract address, such as token name, symbol, decimals, and possibly supply or network information.
