# Base Token Exit Check (Honeypot Detector)

> Base Token Exit Check (Honeypot Detector) is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Simulates a real buy and sell on Uniswap for a Base network token to determine if you can actually exit your position (honeypot check).

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-token-exit-check-honeypot-detector-03f05d0d
```

Example prompt: Before I ape into this token, can you run a honeypot check on the Base contract 0x1234567890abcdef1234567890abcdef12345678 and tell me if I can actually sell it after buying?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
