# Welcome to the OLI API documentation ### What are the OLI API(s) ? The OLI API(s) lets the user run common OLI Calculations quickly and efficiently directly in the cloud, fully managed by OLI. They are exposed as http endpoints and the calculation specification can be passed in easy to understand JSON format. The result of the calculation is also obtained in the same format. This makes it a great choice for automation workflows and does not require the user to install any additional software for running the calculations. This is OLI technology at its core level and the API backend computations you are accessing is the state of science in first-principles electrolyte thermodynamics. Simply put, you are using the best available technology for modeling electrolyte systems. **Please contact OLI sales to create a cloud account to be able to use the OLI API(s).** --- # 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.
