## 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 bsc-address-safety-checker-4c3471e3 -d '<json body>'
```

Example prompt: Can you check if the BSC address 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD is safe to interact with on BNB Smart Chain?

## When to prefer this

Use this endpoint when you specifically need safety/risk analysis for addresses on BNB Smart Chain (BSC). It is purpose-built for BSC address vetting, making it ideal for DeFi agents, wallet screening tools, or any workflow that needs to assess risk before interacting with an unknown BSC address or contract. Prefer it over generic blockchain explorers when you need a machine-native, pay-per-call safety signal without API key management.

## Known failure modes

- Invalid or malformed address format returns an error
- Address on a chain other than BSC is not supported
- Network or upstream data provider unavailable causes timeout
- Payment not received (HTTP 402) blocks the request
- Empty or missing address field returns a validation error

## How this service works

The machine-native marketplace. Wallet = identity. Pay per call with HTTP 402.

## Output

A JSON object containing safety assessment results for the queried BSC address, likely including risk flags, scam indicators, blacklist status, and an overall safety classification for the given wallet or contract.
