## How to call it through Zero

```sh
zero fetch --capability blockrun-ai-67bc3b31
```

Example prompt: Show me the current DeFi protocol rankings by TVL — I want to see which protocols are leading right now.

## When to prefer this

Use this endpoint when you need a ranked leaderboard of DeFi protocols sorted by a specific on-chain metric such as TVL, volume, or fees. Prefer this over general DeFi data endpoints when the goal is comparison and ranking rather than detailed per-protocol data.

## Known failure modes

- Missing required 'metric' query parameter returns 400 or error response
- Invalid or unsupported metric value returns error or empty results
- Upstream data source unavailable returns 5xx error
- Rate limit exceeded or payment failure returns 402 or 429

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

An ordered list of DeFi protocols ranked by the specified metric, including protocol names, rank positions, and corresponding metric values for each protocol.
