# ChemBuilder API ### What is Chemistry Builder Cloud API ? The Chemistry Builder API is a new addition to OLI's cloud services, designed to integrate smoothly with other OLI cloud products. It simplifies the process by allowing users to generate chemistry model files directly in the cloud, eliminating the need for manual creation and upload of .dbs files through OLI's desktop applications. The Chemistry Builder Cloud API requires a JSON file containing essential chemistry data. This file can be generated either programmatically via Chemistry Builder Query APIs or manually from a JSON template. For programmatic creation, users first gather data on inflows, kinetics, or redox through Query APIs, then merge these details into one JSON file. The ChemBuilder Query API offer comprehensive lists of default settings and permissible user selections. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://devdocs.olisystems.com/chemistry-model-files/chembuilder-api.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
