How this service works

Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.

Output

Returns a JSON object with an 'ok' flag, a human-readable verdict string (e.g. 'CAN EXIT: a 0.005 ETH round trip returns X ETH'), buy/sell simulation results including ETH in/out and round-trip loss percentage, liquidity pool details (DEX, version, paired asset), and token owner information. The verdict clearly states whether you can exit the position.

Example use cases

Pre-trade honeypot safety check

“I want to buy this Base token at 0xabc123def456abc123def456abc123def456abc1 but I'm worried it might be a honeypot — can you simulate a buy and sell on Uniswap and tell me if I can exit?”

Memecoin rug-pull screening

“There's a new memecoin on Base called BENJI at contract 0xdeadbeef1234567890abcdef1234567890abcdef — check if it's a honeypot and what the round-trip loss percentage looks like.”

Portfolio token exit verification

“I already hold some tokens on Base at 0x9999aaaa1234567890abcdef1234567890abcdef — can you verify that I can still exit my position and what the sell simulation looks like on Uniswap?”

Technical details

Endpoint

GEThttps://apexfaucet.xyz/api/x402/base-exit-check/%7Btoken%7D?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to verify whether a specific Base network token is a honeypot before trading. It performs a real on-chain simulation rather than just static analysis, making it more reliable than metadata-only checks. Prefer this over generic token info endpoints when the critical question is 'can I actually sell after buying?' and you want a concrete round-trip loss percentage from Uniswap simulation.

Side effects

Token contract address not found on Base — returns error or ok:false
No Uniswap liquidity pool exists for the token — cannot simulate trade
Token is a verified honeypot — sellOk will be false with a sellError message
Invalid contract address format — request fails validation
Payment not received — returns 402 Payment Required
Simulation block data temporarily unavailable — transient error
