## 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-web3identity-com-fbd24599
```

Example prompt: Show me the top DeFi protocols ranked by total value locked right now — I want to see which protocols are leading the market.

## When to prefer this

Use this endpoint when you need a ranked overview of the entire DeFi protocol landscape by TVL, rather than the TVL of a single specific protocol. Prefer this over the single-protocol TVL endpoint when you want comparative rankings or market share analysis across all major DeFi protocols.

## Known failure modes

- Upstream DefiLlama data unavailable — may return stale or empty data
- Payment required (402) if x402 micropayment not provided
- Rate limiting if too many requests in quick succession
- Empty protocol list if data pipeline is down
