## 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 smart-contract-auditor-pro-mcp-877977b9 -d '<json body>'
```

Example prompt: Can you audit this Solidity smart contract code for me and flag any security vulnerabilities or bugs before I deploy it? Here's the contract: [paste contractCode here]

## When to prefer this

Choose this endpoint when you need a fast, automated security audit of EVM-compatible smart contract source code prior to deployment, especially in agentic workflows where on-chain payment settlement via x402 on Base L2 is already integrated. Prefer it over manual audit services when you need programmatic, machine-readable results at $25 USDC per call without gas overhead.

## Known failure modes

- Missing or empty contractCode field returns an error
- Malformed or non-Solidity input may produce incomplete audit results
- Payment failure via x402 protocol results in 402 status and no audit
- Network timeout for large contracts exceeding processing limits
- Invalid contract syntax may cause parsing errors

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object with a transaction hash (txHash) referencing the on-chain settlement and a success boolean, along with the audit findings for the submitted smart contract code including identified vulnerabilities, risk levels, and recommendations.

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
  "success": true
 }
}
