For PancakeSwap traders and LPs

Free tools that read PancakeSwap pools on BNB Chain and say what a trade really costs and what a position really earns. Measured on the chain, for any token. No key, no wallet.

Any token
Any token traded on PancakeSwap: the four cards below read it.
Where to trade

The deepest pool is not always the one that pays most. Every PancakeSwap pool of the token is quoted for the same size, and the best one is named.

Paste a token above.
pancakeswap_best_route
What a trade really costs

What you keep after buying and selling straight back on the best route: both swap fees, the price your trade moves and the token's own tax, measured from its trades. And who holds the LP tokens.

Paste a token above.
bsc_pool_scan
Which fee tier pays an LP

A pair lives in up to five pools. Interfaces rank them by money parked; this ranks them by the fees they actually paid in the last hour.

Paste a token above.
pancakeswap_fee_tiers
How wide a V3 range

Every width replayed over the pool's own recent prices, and the cost of putting a range back counted against it.

Paste a token above.
pancakeswap_range_plan
Your V3 position

Any PancakeSwap V3 position, any pair: in range or not, the room to each edge, what it holds and is owed, and whether collecting pays for its gas.

Paste a position id or a wallet above.

We use it with our own money

The DeFi agent runs this project's CAKE/BNB 0.05% position every day with the same code: the width it keeps is the one that came out ahead when every width was replayed, and every step is a transaction. The result is shown as it is, losses included.

Errors on PancakeSwap, fixed first-hand

What broke for us on PancakeSwap and how it was fixed, each tested on the chain: V3 mints that revert with no reason, 'Pancake: K' on a taxed token, fees that never arrive after removing liquidity.

For agents
  • Every number above is one call, for any token: /api/best-route?address=0x…&usd=250 · /api/pool-scan?address=0x… · /api/fee-tiers?address=0x… · /api/range-plan?address=0x…&capitalUsd=1000 · agent.brainonbnb.com/lp/look?position=<id>
  • The same as MCP tools at brainonbnb.com/mcp, and in llms.txt.
  • Read-only: nothing here signs a transaction or asks for a wallet. The pool scan is free up to 1,000 calls a day per caller.
  • Pools read: PancakeSwap V2, V3 and Infinity CL (hooks included, priced through PancakeSwap's own quoter); Uniswap and Biswap pools are named beside them.
