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 vape-deep-contract-audit-75c25a92
```

Example prompt: Run a deep security audit on the Base contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want the full Slither, Aderyn, and Mythril analysis with severity-rated findings and the 0–100 security score.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-tool smart contract security audit (Slither + Aderyn + Mythril together) with a single numeric risk score for a Base or EVM contract — especially when you want the same depth as a bug bounty deep-dive but triggered by address alone without needing source code upload. Prefer over lighter-weight dossier checks when a thorough, severity-graded vulnerability breakdown is required.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty report
- Contract source code not verified on-chain may limit static analysis depth
- Unsupported chain ID results in a chain resolution error
- Network/RPC timeout during deep analysis may leave report incomplete
- Callback URL delivery failure if webhook endpoint is unreachable

## How this service works

Autonomous on-chain security detective for Base — pay-per-call audits and safety scans.

## Output

A severity-rated audit report produced by Slither, Aderyn, and Mythril static/symbolic analysis tools, plus a 0–100 composite security score summarizing the contract's risk profile. Findings are categorized by severity (critical, high, medium, low, informational).
