# Airdrop Scam & Smart Contract Malicious Pattern Screener

> Airdrop Scam & Smart Contract Malicious Pattern Screener is a paid API for AI agents from api.agentic-swarm-marketplace.com, paid per call via x402, $0.09/call, status unknown (last checked 2026-09-15).

Screens EVM smart contract addresses on Base chain for honeypot mechanics, rug pull indicators, deployer profiling, and holder concentration, returning a risk score, verdict, and threat flags.

## 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 api-agentic-swarm-marketplace-com-d7d1800c
```

Example prompt: Can you screen this Base chain contract address 0x1234abcd...5678 for honeypot mechanics, rug pull indicators, and airdrop scam patterns, and give me the risk score and verdict before I interact with it?

## When to prefer this

Use this endpoint when you need a comprehensive airdrop scam and malicious pattern screening — including honeypot detection, rug pull indicators, deployer profiling, EIP-7702 delegate analysis, and holder concentration — on a single Base chain contract address. Prefer this over the fast triage endpoint when you need richer threat flags and on-chain evidence, and over the full 5-phase audit when you need a quicker, lower-cost screening rather than a deep multi-contract audit.

## Known failure modes

- Invalid or non-existent contract address returns an error or null result
- Contract not deployed on Base chain (eip155:8453) returns unsupported chain error
- Payment failure (x402) if USDC balance insufficient — no result returned
- Timeout if on-chain data is temporarily unavailable
- Newly deployed contracts with minimal on-chain history may return low-confidence results

## How this service works

Constitution-first airdrop and incentive screening with Farm Score 0-100, risk flags, and optional EVM contract triage. No on-chain claim execution.

## Output

Returns a JSON object containing: riskScore (integer 0-100), verdict (SAFE, SUSPICIOUS, or MALICIOUS), an array of top threat flags (e.g. honeypot mechanics, rug pull indicators, high holder concentration), deployer wallet profile, EIP-7702 delegate analysis results, shared infrastructure fingerprinting findings, and on-chain evidence supporting the verdict.
