## How to call it through Zero

```sh
zero fetch --capability chainray-token-screener-f8ebeb50
```

Example prompt: Can you screen the top tokens on Base right now using ChainRay's token screener and show me which ones look most active or promising?

## When to prefer this

Use this endpoint when an agent needs to screen, filter, or discover tokens on a specific blockchain network for DeFi research or investment analysis. Prefer this over general blockchain data endpoints when the goal is to surface a ranked or filtered list of tokens rather than querying a specific token's details.

## Known failure modes

- Unsupported chain identifier returns an error or empty result
- Missing required chain parameter causes a 400 bad request
- Payment of $0.02 USDC not provided results in 402 Payment Required
- Network congestion or upstream data delays may return stale or incomplete token data
- Invalid chain name returns no results or an error message
