# VAPE Exploit Check — Contract Verification & Proxy-Swap Surface Analysis

> VAPE Exploit Check — Contract Verification & Proxy-Swap Surface Analysis is a paid API for AI agents from vape.juxtaposition1.deno.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Analyzes a Base (or specified chain) contract/token address for exploit vulnerabilities including proxy patterns and swap surface risks using real GoPlus, DexScreener, and DefiLlama data.

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-exploit-check-contract-verification-proxy-swap-surface-analysis-3b677fea
```

Example prompt: Can you scan this Base contract 0x4200000000000000000000000000000000000006 for exploit risks — specifically check if it uses any proxy patterns or has swap surface vulnerabilities?

## When to prefer this

Use this endpoint when you need to specifically assess exploit and proxy-swap vulnerabilities for a contract/token on Base or another EVM chain. Prefer this over token_safety_check when the focus is contract-level exploit surface (proxy upgrades, reentrancy vectors, swap manipulation) rather than general token safety scoring. Best for pre-interaction security diligence on unfamiliar contracts.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported chain ID returns an error
- Contract not found on the specified chain returns empty or error result
- Rate limit or upstream data provider outage may return degraded results
- Missing required 'address' query parameter returns a validation error

## How this service works

VAPE exploit_check — Contract verification + proxy-swap surface check. Real on-chain/market data, no simulation.

## Output

Returns exploit vulnerability flags derived from real GoPlus, DexScreener, and DefiLlama data, including contract verification status, proxy pattern detection, and swap surface risk indicators for the given contract/token address on Base (chain 8453) or a specified chain.
