Marketplace API Out of Preview

The Marketplace API is now part of the official GitHub REST API v3.

If you used the Marketplace API during the preview period, you needed to provide a custom media type in the Accept header:

`application/vnd.github.valkyrie-preview+json`

Now that the preview period has ended, you no longer need to pass this custom media type. Instead, we recommend that you specify v3 as the version in the Accept header:

application/vnd.github.v3+json

You can find the Marketplace API here. If you have any questions or feedback, please get in touch with us.
