## 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 primeapi-crypto-contract-verification-3359378e -d '<json body>'

Example prompt: Can you verify whether the smart contract at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is a legitimate, verified contract on-chain?

## When to prefer this

Use this endpoint when an agent needs to confirm the authenticity or verification status of a smart contract before interacting with it, especially in DeFi or NFT workflows where contract legitimacy is critical. Prefer this over generic blockchain explorers when a pay-per-call, no-API-key solution is needed.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unverified or unknown contract returns a not-found or unverified status
- Network timeout or upstream blockchain API failure
- Missing or empty query parameter returns a validation error
- Contract address exists but belongs to an unsupported chain
