# Soul Solidity > Zap infrastructure for DeFi: swaps, LP deposits, staking, bonding and more compressed into a > single atomic transaction. The public product is the SoulZap API, which returns calldata you > submit yourself - it never executes anything. ## Docs - [SoulZap API docs](https://docs.soulsolidity.com): human reference for the API. - [llms.txt for the docs](https://docs.soulsolidity.com/llms.txt): integration guides written for coding agents. Start here if you are integrating. - [llms.txt for the API host](https://api.soulsolidity.com/llms.txt): the whole contract on one page - endpoints, every `lpType` and `protocol`, chains. ## Elsewhere - [GitHub](https://github.com/soulsolidity) - [X](https://twitter.com/SoulSolidity) - [Contact](https://telegram.me/Doublo): custom zap integrations.
