# AdoptOpenJDK API

* **NOTICE:** AdoptOpenJDK API v1 Has now been removed.
* **NOTICE:** AdoptOpenJDK API v2 Has now been deprecated.
* **NOTICE:** If you are using v1 or v2 please move to the [latest version](https://api.adoptopenjdk.net) as soon as possible. Please raise any migration problems as an issue in the [v3 issue tracker](https://github.com/AdoptOpenJDK/openjdk-api-v3/issues/new).
* **NOTICE:** The documentation below is kept for historical purposes.

## Overview

The AdoptOpenJDK API provides a way to consume JSON information about the AdoptOpenJDK releases and nightly builds.  Sign up to the [mailing list](https://mail.openjdk.java.net/mailman/listinfo/adoption-discuss) where major API updates will be announced, and visit [adoptopenjdk.net](https://adoptopenjdk.net) to find out more about the community.

## Deployment

The v2 API is currently deployed on AdoptOpenJDK's Heroku instance.

## Usage

Here is an example using `curl` (see the [curl documentation](https://curl.haxx.se/docs/tooldocs.html)):

```sh
curl -L 'https://api.adoptopenjdk.net/v2/info/releases/openjdk8'
```

This command returns information about all 'OpenJDK' releases, and defaults to the latest version of the API.

The following [Windows Powershell](https://docs.microsoft.com/en-us/powershell/scripting/getting-started/getting-started-with-windows-powershell?view=powershell-6) script uses `Invoke-Webrequest` to download the latest Windows 64-bit archive.

```powershell
function Get-RedirectedUrl
{
    Param (
        [Parameter(Mandatory=$true)]
        [String]$URL
    )

$request = [System.Net.WebRequest]::Create($url)
    $request.AllowAutoRedirect=$false
    $response=$request.GetResponse()

If ($response.StatusCode -eq "Found")
    {
        $response.GetResponseHeader("Location")
    }
}

$url= "https://api.adoptopenjdk.net/v2/binary/nightly/openjdk8?openjdk_impl=hotspot&os=windows&arch=x64&release=latest&type=jdk"

$fUrl = Get-RedirectedUrl $url
$filename = [System.IO.Path]::GetFileName($fUrl);

Write-Host "Downloading $filename"

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
Invoke-WebRequest -Uri $url -OutFile $filename
```

> **Note on the API rate limit:** Add the `-i` option (e.g. `curl -i https://api.adoptopenjdk.net/v2/openjdk8/releases`) to return the response header as well as the response body. There is a limit of 100 API calls per hour per IP, and the value of `X-RateLimit-Remaining` in the response header is useful to determine how many API calls are remaining from this limit.

## API v2.0.0 Specification

You can append different paths to the `https://api.adoptopenjdk.net/v2/` URL, either in the above `curl` format, in a browser, or through an HTTP client, to return different JSON information:

```http
/v2/<request type>/<release type>/<version>
```

For instance /info/nightly/openjdk10:

```sh
curl -L 'https://api.adoptopenjdk.net/v2/info/nightly/openjdk10'
```

### Path Parameters

#### Request Type

##### info

List of information about builds that match the current query

```sh
curl -L 'https://api.adoptopenjdk.net/v2/info/nightly/openjdk8?openjdk_impl=hotspot'
```

##### binary

Redirects to the binary that matches your current query. If multiple or no binaries match the query, an error code will be returned

```sh
curl -L 'https://api.adoptopenjdk.net/v2/binary/nightly/openjdk8?openjdk_impl=hotspot&os=windows&arch=x64&release=latest&type=jdk'
```

##### latestAssets

Returns the latest binary asset for every matching combination of `os`, `arch`, `type`, `openjdk_impl`, and `heap_size` query parameters.

i.e to find the latest jdk/jre for linux, x64, normal heap, hotspot:

```sh
curl -L 'https://api.adoptopenjdk.net/v2/latestAssets/nightly/openjdk8?os=linux&arch=x64&heap_size=normal&openjdk_impl=hotspot'
```

```json

```

#### Release Type

Type of release, i.e `releases` for stable builds or `nightly` for most recent build.

#### Version

OpenJDK version, i.e `openjdk8`, `openjdk9`, `openjdk10`, `openjdk11`, `openjdk12`, `openjdk13`, `openjdk14`, `openjdk15`

### Query Parameters

The data that can be returned can then be filtered to find builds of a specific type

| Parameter | Query Parameter Name | Examples |
|-----------|----------------------|----------|
| JVM Implementation | `openjdk_impl` | `hotspot`, `openj9` |
| Operating System | `os` | `windows`, `linux`, `mac`, `solaris`, `aix` |
| Architecture | `arch` | `x64`, `x32`, `ppc64`, `s390x`, `ppc64le`, `aarch64`, `arm` |
| Binary Type | `type` | `jdk`, `jre` |
| Heap Size | `heap_size` | `normal`, `large` |

In the absence of a given parameter, it will return all elements.

To return latest, hotspot, windows, x64, jdk:

```sh
curl -L 'https://api.adoptopenjdk.net/v2/binary/nightly/openjdk8?openjdk_impl=hotspot&os=windows&arch=x64&release=latest&type=jdk'
```

Multiple values can be supplied for a given parameter like so:

```sh
curl 'https://api.adoptopenjdk.net/v2/info/releases/openjdk8?os=windows&os=linux&arch=x32&arch=x64'
```

This will return all Windows and Linux releases of OpenJDK8 for 32-bit and 64-bit x86 architectures. Multi-value `release` queries are not currently supported due to some idiosyncrasies with how it affects response formats. Queries such as `?release=latest&release=jdk8u172-b00-201807161800` will return an appropriate error response.
