## 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 basebuilder-defi-tvl-rankings-f0a3a6de -d '<json body>'
```

Example prompt: Show me the top DeFi protocols ranked by TVL on Base — I want to see which protocols like lending, DEXes, or yield vaults are dominating right now.

## When to prefer this

Use this endpoint when you need a ranked comparison of DeFi protocols by TVL specifically within the Base ecosystem or cross-chain DeFi landscape. Prefer this over general crypto price APIs when the goal is protocol-level TVL analysis rather than token prices or wallet balances.

## Known failure modes

- Invalid or unsupported chain parameter returns 400 error
- Payment not received results in 402 Payment Required
- Server or data provider outage returns 500
- No protocols found for given filter criteria returns empty list
- Stale or delayed TVL data if upstream indexer is lagging
