# Query Contracts Ambient protocol has additional stateless query contracts to provide easy and convenient access to contract data in a simple way. Because all methods in these contracts are view type, they can be called in either an on-chain or off-chain contract. Additional or future versions of these contracts may be deployed over time, but existing query contracts are immutable and will always be available on-chain at current address with full backwards compatibility. The two available query contracts are * CrocSwapQuery - Suite of methods to query liquidity positions, curve liquidity and prices, and user dex balances * CrocImpact - Calculates price impact of a given swap operation --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
