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 JSON object with a UUID scan ID, the chain and contract address, a weighted risk score from 0 (safe) to 100 (critical), a verdict enum (safe/low_risk/medium_risk/high_risk/critical/uncertain), an array of heuristic flags with severity levels, a 30-day rug probability estimate (0–1), score confidence level, a summary object with honeypot/LP/owner/concentration details, and a disclaimer.
Example use cases
Evaluate new DeFi token safety
“I found a promising Solana token that just launched. Can you run a quick rug check on it and let me know if there are any major red flags I should worry about before I invest?”
Assess holder concentration risk
“I'm looking at this Base token and want to understand if the top holders are too concentrated. Check the contract and tell me if it looks safe or if there's a rug pull risk.”
Screen tokens for honeypot indicators
“Before I add this token to my portfolio, scan its smart contract on Base for honeypot behavior, LP lock status, and ownership risks. Give me a clear verdict on whether it's safe to buy.”
Technical details
Endpoint
GEThttps://rugguard.redfleet.fr/v1/pretrade/checkWhen to prefer
Use this endpoint when an AI agent needs a fast, pay-per-call (no API key required) pre-trade safety signal for a specific token contract on Base (EVM, 14 heuristics) or Solana (SPL, 5 heuristics). Prefer it over generic blockchain explorers when you need a structured risk score, rug probability, and severity-tagged flags in a single API call without a subscription.
Side effects
- Invalid contract address format returns an error (not a 40-hex EVM address or valid base58 Solana mint)
- Unsupported chain value (not 'base' or 'solana') returns a validation error
- Contract with no on-chain data returns verdict 'uncertain' with score_confidence 'insufficient_data'
- Payment failure via x402 protocol results in 402 response blocking the call
- Network timeout if the chain RPC is slow or unavailable
