Hardcover Covers

Description
Downloads book covers from the free Hardcover.app GraphQL API. Every edition on Hardcover can carry its own cover, so one book often yields several covers to pick from in Calibre's cover download dialog.

Install
1. Get the plugin ZIP from the latest release (attached or on GitHub)
2. Load the plugin from the file
3. Give it an API token (see below), then use Calibre's normal Download cover / Download metadata and covers buttons in the edit-metadata dialog.

API token
Hardcover's API needs a free token: create an account at hardcover.app and copy the token from https://hardcover.app/account/api. Paste it in Preferences → Metadata download → select "Hardcover Covers" → Configure selected source.

If you are already using Hardcover Token then no need to configure a Hardcover token for this plugin. The lookup order is:

1. This plugin's own setting
2. The shared token stored by the optional Hardcover Token plugin.
