Base Launch Guard – Batch Token Safety Check
x402
Base Launch Guard – Batch Token Safety Check is a paid API for AI agents from guard.facts402.com, paid per call via x402, $0.3/call, status unknown (last checked 2026-11-01).
Runs a comprehensive pre-trade and position safety analysis on up to 10 Base memecoin/new token contracts, returning honeypot, rug pull, tax, exit liquidity, insider/sniper forensics, and deployer risk data.

How this service works
Batch Base token safety reports for up to 10 tokens: the full honeypot, tax, exit-liquidity, insider/sniper/bundle, deployer rug-history, privileges and liquidity report for each token, deduplicated and run in parallel. For screeners ranking new Base launches and memecoins.
Output
A JSON report per token containing: verdict with risk reason codes and severities, honeypot/tax simulation results, exit liquidity simulation (net USD received, price impact, max safe position size), LP lock/burn status, market data (FDV, liquidity, 24h volume, pool age), and insider/sniper/bundle forensics where indexed. Also returns the block number and whether results were cached.
Example use cases
Pre-buy rug pull check on new launch
“I'm about to ape into this new token on Base at 0x1234567890abcdef1234567890abcdef12345678 — can you check if it's a honeypot, what the buy/sell taxes are, whether the LP is locked, and if there's any sniper or insider activity I should know about?”
Exit liquidity check before selling
“I have about $2000 worth of this Base memecoin at 0xabcdefabcdefabcdefabcdefabcdefabcdefabcd — can you simulate what I'd actually receive if I sold my whole position right now and tell me the price impact and slippage?”
Batch safety screen for multiple tokens
“Can you run safety checks on these three Base tokens at once — 0xaaaa...1111, 0xbbbb...2222, and 0xcccc...3333 — I need to know which ones are safe to trade, flag any honeypots or rugs, and check the deployer track record on each.”
Technical details
Endpoint
POSThttps://guard.facts402.com/v1/guard/batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive multi-signal safety report on one or more Base mainnet tokens before trading — especially for new launches, memecoins, or unknown deployers. Prefer this over single-token endpoints when checking multiple tokens at once (up to 10 per call). It is especially valuable when you need exit-liquidity simulation at your specific position size, not just a generic safety flag. Choose this over generic on-chain data APIs when you need forensic signals like sniper/bundle detection, funder cluster analysis, and deployer track record in a single call.
Side effects
- Token not indexed — forensics and deployer data unavailable (returns DATA_UNAVAILABLE_NOT_INDEXED info-level reason, not an error)
- Invalid contract address format — rejected by schema validation
- Concentrated-liquidity (CL) pools — LP lock percentage cannot be measured, returns lock_status: unknown_cl
- Trade simulation reverted — exit liquidity sim may fail for truly illiquid or honeypot tokens
- Position size too large or too small — must be between $1 and $10,000,000
- More than 10 tokens in a single batch — rejected
- Payment failure — x402 payment of $0.30 USDC required per call
