## 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 ragradar-on-chain-yield-data-70db38ac
```

Example prompt: Pull the current on-chain yield data from RagRadar across Base and Arbitrum so I can see which DeFi protocols are offering the best rates right now.

## When to prefer this

Use this endpoint when you need real-time on-chain DeFi yield data across multiple EVM and Solana chains simultaneously, especially when building automated agents that need to compare yield opportunities. Prefer over manual blockchain scanning when you need aggregated multi-chain yield intelligence in a single call with x402 micropayment billing.

## Known failure modes

- Payment failure: x402 micropayment of $0.02 USDC not completed or rejected
- Invalid properties filter parameter returns malformed response
- Network unavailable: backup domain may have degraded uptime
- Rate limiting if too many rapid successive calls
- Empty result set if no yield data available for requested filter
