# Welcome to Semantic Chemist documentation!

## Overview

The Semantic Chemist DB manages data about chemical substances that can be found on PubChem. The API supports the following types of requests:

* **Search by SMILES**: Allows users to search for chemical substances using their SMILES (Simplified Molecular Input Line Entry System) notation.
* **Search by IUPAC**: Enables searching by the International Union of Pure and Applied Chemistry (IUPAC) name of the chemical substance.
* **Search by Name**: Supports searches by both IUPAC names and synonyms of the chemical substance.
* **Search by CID**: Allows users to search using the PubChem Compound Identifier (CID).
