## 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 stealthguard-defi-yield-radar-4d4cce5a -d '<json body>'
```

Example prompt: What are the top stablecoin and ETH APY yields on Base right now? I want the best current rates across protocols, pre-screened and safe for my agent pipeline.

## When to prefer this

Choose this endpoint when you need live, agent-safe DeFi yield data on Base specifically, and require pre-sanitized output free from prompt-injection risks. Ideal for autonomous agent pipelines that cannot afford to process raw, potentially malicious DeFi data themselves.

## Known failure modes

- No live yield data available if Base RPC is unreachable
- Stale data if upstream DeFi protocol APIs are slow or unavailable
- Payment failure if x402 micropayment of $0.002 USDC is not completed
- Invalid request body schema returns error
- Protocol outage on Render hosting causing 503
