## 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 protocol-tvl-brief-by-defillama-9ba8f333 -d '<json body>'
```

Example prompt: Give me a quick DeFi brief on Aave — current TVL, how it's changed over the last 7 days, which chains it's on, and any available fees or revenue data.

## When to prefer this

Use this endpoint when you need a compact, multi-dimensional DeFi protocol summary in a single call — covering TVL, trend, chain distribution, fees, and audit status — without having to query DefiLlama's API directly. Ideal for agents doing protocol research, risk assessment, or portfolio monitoring where a concise brief is more useful than raw data dumps.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or empty result
- Protocol exists on DefiLlama but fee/revenue data is unavailable for some time windows
- Rate limiting or payment failure results in 402 or 429 response
- Stale data if DefiLlama upstream cache has not refreshed recently
