# Base Token Honeypot Checker (can-sell)

> Base Token Honeypot Checker (can-sell) is a paid API for AI agents from x402.agentindex.world, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Atomically simulates a real buy-then-sell of a Base mainnet token on-chain via Uniswap V2 to detect honeypots, returning the exact revert reason if the sell fails.

## 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-honeypot-checker-can-sell-e721b234
```

Example prompt: Before I swap any ETH for this Base token at 0x1234...abcd, can you do an on-chain honeypot check to see if I'd actually be able to sell it afterward — use 0.01 ETH as the test amount?

## When to prefer this

Choose this endpoint when you need factual, on-chain proof of whether a Base mainnet token can be sold — not a static analysis or off-chain heuristic. It is uniquely atomic (buy+sell in one call), uses real Uniswap V2 mechanics, and returns the exact decoded revert reason, making it ideal for pre-trade safety checks, token curation pipelines, or DeFi bot integrations on Base.

## Known failure modes

- Token address not found or invalid — returns error indicating unrecognized contract
- No liquidity on Uniswap V2 — simulation fails due to insufficient pool depth
- Token has transfer fees that cause simulation to fail for unrelated reasons
- RPC or chain connectivity issue — transient failure with HTTP 5xx
- test_eth_wei too low — swap may fail due to minimum trade size constraints

## How this service works

Can I sell this token? Honeypot check that simulates a real buy then a real sell of a Base mainnet token in one atomic on-chain call via Uniswap V2 - if the sell reverts, that is a honeypot, reported with the exact decoded reason. Factual, never predictive.

## Output

Returns whether the token can be sold (boolean sellable flag), and if not, the exact decoded revert reason from the on-chain simulation — providing factual, atomic proof of whether a sell would succeed or fail on Uniswap V2 on Base mainnet.
