## 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 kristo-intelligence-api-defi-protocol-safety-9efcb985
```

Example prompt: Can you check the safety rating for a DeFi protocol on Base blockchain and tell me whether it's considered risky before I deposit funds?

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-call DeFi protocol safety intelligence specifically for the Base blockchain. It is ideal for agents that need to perform one-off risk checks before recommending or executing DeFi interactions, without committing to a subscription. Best suited for Base-specific protocol evaluation rather than multi-chain or Ethereum mainnet analysis.

## Known failure modes

- Payment not fulfilled — returns 402 if 0.1 USDC payment is not included
- Invalid or missing protocol identifier — returns error or empty data object
- Unsupported data source specified — may return null or error response
- Protocol not found on Base blockchain — returns empty or partial data
- Network/infrastructure issues with Vercel deployment — returns 5xx error
