How to get a Cloudflare R2, Bunny or Backblaze B2 API key

Easemic connects to S3 storage with one key. Pick your provider, watch where the key lives, and paste it in the app: Easemic recognises the provider, then finds or creates a bucket called easemic-comics on its own.

Then, in Easemic

  1. Tap More, then Cloud library.
  2. Choose Quick setup with API key and paste the key or token.
  3. Tap Connect easemic-comics.

Using Google Drive, OneDrive or a WebDAV drive instead? No key is needed: sign in, or enter your WebDAV address.

Cloudflare R2

R2 has to be turned on once in the Cloudflare dashboard (R2 Object Storage) before any token can use it, and Cloudflare asks for a payment card to do that. The first 10 GB are free.

Bunny.net

This is your account API key. Easemic uses it to find or create a storage zone called easemic-comics.

Backblaze B2

Generating a new master key cancels the old one. If other apps already use your master key, skip this and use Custom S3 credentials in Easemic with a key for one bucket instead. From the master key, Easemic creates its own key for S3 access and the easemic-comics bucket.

Questions people ask

Which Cloudflare permission does an R2 API token need?

Account · Workers R2 Storage · Edit. Easemic uses the token to find or create the easemic-comics bucket and then to read and write comics in it, so a read-only token is not enough.

Where is my Bunny.net API key?

In the Bunny dashboard, open the account menu and choose API key. It is the account-wide key, not a storage zone password.

How do I paste a Backblaze B2 key into Easemic?

Paste keyID:applicationKey with a colon between them, or the two values on two lines. Easemic tells the providers apart by the shape of the key.

Does Easemic send my API key anywhere?

Only to the storage provider it belongs to. The key stays on your phone; Easemic has no server that sees it or your comics.
