Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 beezshield-contract-risk-scorer-37cfbbb5 -d '<json body>'
```

Example prompt: Before my agent calls that contract at 0x1234abcd...5678 on Base, can you run a BeezShield risk score on it so I know if it's safe to interact with?

## When to prefer this

Use BeezShield's risk scorer when an AI agent needs a pre-execution trust signal before interacting with an unknown or third-party smart contract on Base, especially in automated DeFi workflows where human review is not feasible. Prefer this over generic blockchain explorers when you need a machine-readable risk score rather than raw contract metadata.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported chain identifier results in a validation error
- Contract not yet indexed may return no score or low-confidence result
- Payment failure via x402 lane results in 402 response and no score
- Network timeout or upstream service unavailability

## How this service works

BeezShield delivers Machine Trust Infrastructure with Sentinel Alpha, a pre-execution decision engine for agents on Base with x402 lane pricing and ERC-8004 identity proof.

## Output

A risk score or trust assessment for the specified contract address, indicating the safety level of interacting with that contract pre-execution, powered by Sentinel Alpha.
