## 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-risk-score-5f88cf0b
```

Example prompt: Before I send funds, can you check the on-chain risk score for wallet address 0x1234abcd5678ef... on Base using RagRadar?

## When to prefer this

Choose this endpoint when you need a fast, per-address on-chain risk score specifically for Base, Arbitrum, or Solana addresses, and when paying per-call via x402 micropayments is acceptable. Prefer it over manual block explorer lookups when you need a structured, agent-consumable risk signal rather than raw transaction history.

## Known failure modes

- Invalid or malformed address returns an error response
- Address not found on supported chains may return empty or low-confidence result
- Network timeouts for chains with slow RPC nodes
- Unsupported chain addresses (e.g. Ethereum mainnet) may return no data
- Payment failure via x402 micropayment protocol blocks the request

## Output

A JSON object containing a status field and on-chain risk intelligence for the queried address, likely including a risk score or rating, flags for suspicious behavior, and contextual signals derived from blockchain activity across supported networks (Base, Arbitrum, Solana).
