# NuGet API **(FREE)**
This is the API documentation for [NuGet Packages](../../user/packages/nuget_repository/index.md).
WARNING:
This API is used by the [NuGet package manager client](https://www.nuget.org/)
and is generally not meant for manual consumption.
For instructions on how to upload and install NuGet packages from the GitLab
package registry, see the [NuGet package registry documentation](../../user/packages/nuget_repository/index.md).
NOTE:
These endpoints do not adhere to the standard API authentication methods.
See the [NuGet package registry documentation](../../user/packages/nuget_repository/index.md)
for details on which headers and token types are supported.
## Package index
> Introduced in GitLab 12.8.
Returns the index for a given package, which includes a list of available versions:

| Attribute | Type | Required | Description |
| -------------- | ------ | -------- | ----------- |
| `id` | string | yes | The ID or full path of the project. |
| `package_name` | string | yes | The name of the package. |
```shell
curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/index"
```
Example response:
```json
{
"versions": [
"1.3.0.17"
]
}
```
## Download a package file
> Introduced in GitLab 12.8.
Download a NuGet package file. The [metadata service](#metadata-service) provides this URL.

```
Write the output to a file:
```shell
curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/1.3.0.17/mynugetpkg.1.3.0.17.nupkg" > MyNuGetPkg.1.3.0.17.nupkg

```
## Route prefix
For the remaining routes, there are two sets of identical routes that each make requests in
different scopes:
- Use the group-level prefix to make requests in a group's scope.
- Use the project-level prefix to make requests in a single project's scope.
The examples in this document all use the project-level prefix.

/groups/:id/-/packages/nuget`
```
| Attribute | Type | Required | Description |

## Service Index
> Introduced in GitLab 12.6.
Returns a list of available API resources:
```plaintext
GET <route-prefix>/index
```
Example Request:
```shell
curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/projects/1/packages/nuget/index"
```
Example response:
```json

The URLs in the response have the same route prefix used to request them. If you request them with
the group-level route, the returned URLs contain `/groups/:id/-`.
