# AlchemyML API Documentation
Version Date: 2021-05-28
<hr>
## Prerequisites
* Python >= 3.6
* * requests >= 2.22.0
* * urllib3 >= 1.25.7
## Module Overview
### Description
AlchemyML is a multi-environment solution for data exploiation.
To maximize customer convenience, there are three ways to run it: via the AlchemyML Platform, via the API, and via ad hoc solutions. The one documented below is the second tool, AlchemyML API.
AlchemyML API is an easy way to use advanced data analysis techniques in Python, accelerating the work of the data scientist and optimizing her/his time and resources.
AlchemyML API has operations at the dataset level (upload, list, delete...), at the experiment level (create, send, add to project, view metrics and logs...) and at the project level (create, update, delete...). Moreover, it also has specific actions so that the client can perform her/his own experiment manually: pre-process the dataset, remove highly correlated columns, detect outliers, impute missings...

```
##### Description
Through this method you can enter operational information related to each column: in this way you can specify what are the operating limits of a column and its tolerances.
You can also indicate some values that you know and that occur within the values of the column so that the _impute_outliers_ module does not take them into account.
In addition, you can group the time-dependent columns by intervals (morning/evening/night) and you can detail whether the behavior of a column depends on the categories of another categorical column.
##### I/O
* Parameters:
* _**experiment_name**_ (_str_): Name of the experiment on which process will take place.
* _**columns_info**_ (_str_/_list_/_dict_): Information on columns.

```
##### Description
This method gives the option of detect outliers. Different strategies are available, as univariate, bivariate, multivariate, complete.
