## 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-protocol-risk-assessment-7581d1a9 -d '<json body>'
```

Example prompt: Can you assess the protocol risk for Aave on the Ethereum mainnet and give me a risk score and breakdown of the main risk factors before I commit any funds?

## When to prefer this

Use this endpoint when an AI agent needs to evaluate the safety and risk profile of a specific DeFi protocol before recommending it to a user, allocating funds, or integrating it into a DeFi workflow. Prefer this over generic smart contract audits when you need a scored, structured risk output rather than a raw audit report.

## Known failure modes

- Unknown or unsupported protocol identifier returns an error or empty result
- Invalid blockchain network specified causes a 400 bad request
- Protocol contract address not found on-chain leads to lookup failure
- Service unavailable or timeout if on-chain data sources are unreachable
- Insufficient metadata for newer or obscure protocols may yield low-confidence scores
