# 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).

# 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://semanticchemistdocs.knowledgator.com/welcome-to-semantic-chemist-documentation.md?ask=<question>
```

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.
