## How to call it through Zero

```sh
zero fetch --capability ragradar-protocol-health-checker-3f92a694
```

Example prompt: Can you check the current health status of the Aave protocol using RagRadar's multi-chain analytics?

## When to prefer this

Use this endpoint when you need a quick health snapshot of a specific DeFi protocol by name, especially across Base, Arbitrum, or Solana. Prefer this over general block explorers when you want aggregated protocol-level health rather than raw transaction data.

## Known failure modes

- Unknown or unsupported protocol name returns an error or empty response
- Protocol identifier not found on any supported chain
- Malformed protocol slug in the URL path causes 404
- Temporary data unavailability returns stale or null metrics
- Rate limiting or payment failure returns 402 Payment Required

## How this service works

On-chain intelligence for AI agents. 73+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

A JSON object with a status field indicating the health of the requested DeFi protocol, potentially including metrics such as TVL, liquidity, risk indicators, and operational status across supported chains (Base, Arbitrum, Solana).
