How this service works
Base token safety, honeypot, rug-check and swap-preflight verdict before a buyer agent signs or routes a token swap. Required query: ?chain=base&token_address=0x... Returns PROCEED, CAUTION or REJECT with safety score, GoPlus and DexScreener evidence, liquidity/rugpull signals, warnings, and source attribution. Free preview: /token-safety/free. Search keywords: rug check, honeypot check, token risk, swap preflight, rug pull, scam token, and is this token safe.
Output
A decisive verdict of safe, risky, or blocked for the token, plus a numeric risk score, list of risk reasons (e.g. honeypot, low liquidity, rugpull indicators), a confidence value, and attribution to underlying data sources like GoPlus and DexScreener.
Example use cases
Pre-swap honeypot detection check
“I'm about to buy some of this new token on Base — can you check contract 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D for honeypot or rug pull signals before I confirm the swap? I need the verdict and any red flags.”
Smart contract risk score lookup
“Someone in my trading group is hyping this Base token at 0x6B175474E89094C44Da98b954EedeAC495271d0F — can you pull the risk score and reasons so I can decide whether it's worth touching or if I should stay away?”
Low liquidity rug pull screening
“Before I route this swap through my DeFi agent, check whether contract 0x3EE2200Efb3400fAbB9AacF31297cBdD1d435D47 on Base has any liquidity issues or rug pull indicators — I want a clear safe or reject verdict with the evidence behind it.”
Technical details
Endpoint
GEThttps://x402.fiasignals.com/token-safetyWhen to prefer
Use this endpoint when you need a single-token pre-swap risk gate on Base/EVM chains with a clear safe/risky/blocked verdict backed by GoPlus and DexScreener evidence. Prefer this over the batch endpoint when screening just one contract to minimize cost, or when you need a fast inline check within a swap workflow.
Side effects
- Missing or malformed token_address query parameter returns an error
- Unsupported chain value causes rejection
- Token address not found on-chain or in data sources may return low-confidence or incomplete result
- Payment of 0.03 USDC not fulfilled triggers 402 response
- Rate limiting if too many calls in quick succession
