Sign in at atlascloud.ai, open API keys in the console and create a key. It starts with apikey-. Atlas Cloud takes generation costs from your Atlas Cloud balance, so add funds to your account too.
atlascloud.ai/console/api-keys →In Phersa, open Settings, go to API keys and choose Atlas Cloud. Paste the key and click Save & verify.
Phersa first checks that the key starts with apikey-, then tests it with Atlas Cloud. A key Atlas Cloud rejects is not stored. Saved keys are encrypted, and once connected the Atlas Cloud panel in Settings shows your balance in dollars.
In the app, pick a model that runs on Atlas Cloud. You see the cost in dollars before you generate, such as $0.08 for a 1K Nano Banana 2 image.
