# BABA Labs PoolLens API

> Read-only, verifiable state of concentrated-liquidity pools and LP positions on Base and HyperEVM.
> Each answer is one eth_call to the open-source PoolLens contract (0xADebbd5825B033bCD4B84FB019AbFC673406d902) at one block, and the
> response includes that block and the call data so you can check it against any RPC that serves
> historical state. proof.blockNumber is the block the call actually executed at; proof.blockHonoured
> says whether the RPC executed at the block requested.
