# API Documentation

* The cool thing about FastAPI is that it's self documenting
* Meaning that you don't have to create any sort of API documentation
* This is done by using Swagger UI
* And is accessed by using the base ROOT URL with <mark style="color:orange;">`/docs`</mark>&#x20;

Example:

```markup
http://127.0.0.1:8000/docs
```

* It redirects you to a page with all the documentation

* Additionally this also allows you to see what is required to run the query successfully and try it out from the documentation itself

* There is an alternative documentation tool as well called Redoc
* This can be accessed by using the base URL + <mark style="color:orange;">`/redoc`</mark>
