## 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 cybercentry-ethereum-token-verification-cetv-api-d58a884f
```

Example prompt: Can you run a security verification on the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum Mainnet (chain ID 1, platform ID 1 for Etherscan) and tell me if it's safe?

## When to prefer this

Use this endpoint when you need to verify the security and legitimacy of a specific EVM-compatible smart contract before interacting with it, investing in a token, or integrating it into a workflow. Ideal for DeFi due diligence, token vetting pipelines, or fraud detection in crypto applications. Supports multiple chains (Ethereum, BSC, Polygon, Base, etc.) via configurable chain_id and platform_id parameters.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported chain_id or platform_id combination returns an error
- Contract address not found on the specified chain returns a not-found response
- Network timeout or upstream blockchain API unavailability
- Missing required parameters (chain_id, contract_address, or platform_id) returns validation error

## How this service works

Verify Ethereum and EVM-compatible contract addresses using the Cybercentry Ethereum Token Verification (CETV) API. Returns a verification_report with detailed security analysis

## Output

Returns a verification_report object containing a detailed security analysis of the specified smart contract, including risk indicators, contract legitimacy signals, and other security-relevant findings for the given EVM-compatible chain and block explorer platform.
