# Python compatibility
<a name="python-compatibility"></a>

CodeArtifact does not support PyPI's `XML-RPC` or `JSON` APIs.

CodeArtifact supports PyPI's `Legacy` APIs, except the `simple` API. While CodeArtifact does not support the `/simple/` API endpoint, it does support the `/simple/<project>/` endpoint.

For more information, see the following on the Python Packaging Authority's GitHub repository.
+ [XML-RPC API](https://github.com/pypi/warehouse/blob/main/docs/dev/api-reference/xml-rpc.rst)
+ [JSON API](https://github.com/pypi/warehouse/blob/main/docs/dev/api-reference/json.rst)
+ [Legacy API](https://github.com/pypi/warehouse/blob/main/docs/dev/api-reference/legacy.rst)

## pip command support

The following sections summarize the pip commands that are supported, by CodeArtifact repositories, in addition to specific commands that are not supported.

+ [Supported client-side commands](#supported-pip-client-side-commands)

### Supported commands that interact with a repository
<a name="supported-pip-commands-that-interact-with-a-repository"></a>

This section lists `pip` commands where the `pip` client makes one or more requests to the registry it's been configured with. These commands have been verified to function correctly when invoked against a CodeArtifact repository.


****  

| Command | Description | 
| --- | --- | 
|   [install](https://pip.pypa.io/en/stable/reference/pip_install/)   |  Install packages.  | 
|   [download](https://pip.pypa.io/en/stable/reference/pip_download/)   |  Download packages.  | 

CodeArtifact does not implement `pip search`. If you have configured `pip` with a CodeArtifact repository, running `pip search` will search and show packages from [PyPI](https://pypi.org/).

### Supported client-side commands
<a name="supported-pip-client-side-commands"></a>

These commands don't require any direct interaction with a repository, so CodeArtifact does not need to do anything to support them.
