## 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 button-money-smart-contract-audit-39d3f702 -d '<json body>'

Example prompt: Can you audit the smart contract at 0x1234abcd...5678 on Base (chain ID 8453) and tell me if there are any vulnerabilities or security issues I should know about before interacting with it?

## When to prefer this

Use this endpoint when you need a quick, AI-summarized security audit of a specific smart contract address, especially on Base (chain 8453). Prefer this over full token security scans when you specifically want a contract-level vulnerability report rather than token-level metadata analysis.

## Known failure modes

- Invalid or malformed contract address returns a 400 error
- Contract address not found on the specified chain returns an empty or error result
- Unsupported chain ID returns an error indicating the chain is not supported
- Payment not provided or insufficient results in a 402 Payment Required response
- Network timeout or provider downtime results in a 503 or timeout error
