# RugGuard Deep Scan — Smart Contract Rug Check

> RugGuard Deep Scan — Smart Contract Rug Check is a paid API for AI agents from rugguard.redfleet.fr, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-10).

Performs a deep heuristic rug-pull risk scan on a crypto smart contract (Base EVM or Solana), returning a weighted risk score, verdict, and detailed flag list.

## Facts

- Endpoint: GET https://rugguard.redfleet.fr/v1/scan/deep/%7Bchain%7D/%7Bcontract%7D
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/rugguard-deep-scan-smart-contract-rug-check-85eb6f2d

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 rugguard-deep-scan-smart-contract-rug-check-85eb6f2d
```

Example prompt: Run a deep rug check on the Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I want to know the risk score, verdict, and any critical flags before I buy.

## When to prefer this

Use this endpoint when an AI agent needs a fast, structured, pay-per-call rug-pull risk score for a specific token contract on Base (EVM, 14 heuristics) or Solana (5 heuristics) before executing a trade. Prefer over generic blockchain explorers when you need a machine-readable verdict, weighted score, and per-flag severity breakdown without requiring API key management — just USDC micropayment via x402.

## Known failure modes

- Invalid chain identifier returns validation error
- Malformed contract address (wrong length or non-hex for EVM) returns 400
- Contract not found on specified chain returns uncertain verdict or error
- Insufficient on-chain data returns score_confidence=insufficient_data
- Service unavailable returns 5xx; agent should retry
- Payment failure via x402 prevents scan from executing

## How this service works

Pay-per-call rug check for crypto smart contracts. Built for AI agents on Agentic.market (x402). USDC fractional pricing, no API key.

## Output

Returns a UUID scan ID, chain, contract address, weighted risk score (0–100), verdict enum (safe/low_risk/medium_risk/high_risk/critical/uncertain), array of heuristic flags with severity codes, 30-day rug probability estimate, score confidence level, elapsed scan time in ms, and a disclaimer. Also includes per-heuristic breakdown with evidence strings, pass/fail decisions, and weights.
