Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-ai-vulnerability-intelligence-engine-dff09c84 -d '<json body>'
```

Example prompt: Can you do a deep AI security audit on the Base contract at 0x1234abcd... and flag any logic vulnerabilities or exploitable attack vectors in it?

## When to prefer this

Choose this endpoint when you need AI-powered security analysis specifically targeting Base network smart contracts, particularly for detecting nuanced logic vulnerabilities and novel exploit patterns that go beyond static rule-based linters. Best suited for pre-deployment audits, post-incident forensics, or due diligence on unknown contracts at low cost ($0.001 per call).

## Known failure modes

- Invalid or non-existent Base contract address returns an error or empty findings
- Malformed or unparseable Solidity source returns an analysis error
- Ambiguous prompt without code or address may yield generic rather than targeted findings
- Network timeout on Render.com free-tier cold starts causing delayed or failed responses
- Payment failure via x402 protocol blocks access before analysis begins

## How this service works

Deep AI Vulnerability & Intelligence Engine. Scans contracts and code for logic vulnerabilities and exploits on Base.

## Output

Returns an AI-generated security assessment detailing discovered logic vulnerabilities, exploit vectors, attack patterns, and risk indicators found in the provided contract source code or deployed Base contract address.
