How this service works
Is this token safe to buy, or a honeypot or rug pull? Checks a Solana or EVM token before you buy, hold or accept it (mint or freeze authority still active, LP not locked, buy/sell tax, low liquidity, brand-new token, concentrated holders) and answers green/orange/red with a grade (SAFE/CAUTION/RISKY/AVOID), the reasons, a one-line summary and market data. Bulk: 100 checks for $0.80 via /v1/credits.
Output
Returns a verdict object with a grade (SAFE, CAUTION, RISKY, or AVOID), a one-liner summary, an array of reason objects each with a code, severity (red/orange/info), and optional details, plus market data from DexScreener including price, liquidity, market cap, 24h volume, and token age. Also includes a signed receipt for proof of check.
Example use cases
Pre-buy honeypot check on new token
“I'm about to ape into this new Ethereum token at 0x6982508145454Ce325dDbE47a25d4ec3d2311933 — can you run a safety check and tell me if it's a honeypot, if LP is locked, and whether there are any red flags I should know about?”
Solana memecoin rug pull scan
“Someone sent me a Solana token contract DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 — is it a rug pull or safe to hold? Check for mint authority, freeze authority, concentrated holders, and give me the grade.”
DeFi agent token acceptance filter
“Before my bot accepts this BSC token at 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c as payment, can you verify it's not AVOID-grade — check liquidity, buy/sell tax, and whether the LP is locked?”

Endpoint
GEThttps://presign-guard.fizzl.eu/v1/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to autonomously assess token safety before executing a buy, accepting a token as payment, or recommending a token to a user — especially for newly launched tokens on Solana, Base, Ethereum, Arbitrum, Optimism, Polygon, or BSC. Prefer this over manual blockchain explorers when you need a structured, graded risk signal with specific red-flag codes rather than raw on-chain data.
Side effects
- Unknown or unlisted token returns no market data (market field null)
- Invalid chain/address combination returns error
- Token too new to have DexScreener data — market data absent
- Unsupported chain returns validation error
- Network timeout from upstream DexScreener or on-chain RPC
- Payment not processed results in 402 response
