Anthropic API Key
00

Before you start

Use Anthropic Console API billing.

  • An email address or supported sign-in for an Anthropic Console account.
  • A payment method for prepaid Claude API usage credits.
  • Lakeview Lister installed so you can test the key before closing the creation flow.
Claude chat plans and Console API usage are separate.

Create the developer key and buy API usage credits at platform.claude.com . A paid plan for chatting with Claude does not fund API requests.

01

Create or choose the account

Open Anthropic Console.

  1. Sign in to Anthropic Console.

    Open the official Claude Platform and create an account if needed.

  2. Confirm the correct organization.

    If you belong to multiple organizations, choose the one that should own Lakeview Lister’s key and pay for its API usage.

  3. Choose a workspace.

    The Default workspace works. A dedicated Lakeview Lister workspace gives you clearer usage and cost reporting without mixing this key with other applications.

Workspace choice matters.

Anthropic API keys are scoped to a workspace. Creating a separate workspace makes it easier to revoke access or review Lakeview Lister’s costs later.

02

Prepare for API requests

Buy Claude API usage credits.

  1. Open Billing settings.

    Go to Settings › Billing in Anthropic Console.

  2. Add payment details.

    Enter the billing information requested for the organization that will own the key.

  3. Purchase a small starting credit balance.

    Anthropic’s API uses prepaid usage credits. Choose an amount appropriate for testing and your initial listing volume.

  4. Decide whether to enable auto-reload.

    Auto-reload can prevent interruptions when the balance gets low. If you enable it, set a refill amount and monthly ceiling you are comfortable with.

Credits are not a subscription.

Anthropic documents API credits as prepaid, non-refundable, and expiring one year after purchase. Start small and monitor usage before buying a large balance.

Check the current rates before buying credits.

Anthropic’s rates vary by model and usage. Review Anthropic’s pricing before funding the account; your Anthropic account is the source of truth for charges.

03

Generate the credential

Create a dedicated API key.

  1. Open API Keys.

    Go to Settings › API Keys .

  2. Select Create Key.

    Name it Lakeview Lister and assign it to the Default workspace or the dedicated workspace you prepared.

  3. Choose an expiration.

    Select a duration you can maintain. A shorter expiration improves security but requires timely rotation; Never avoids an unexpected expiration but should be used only when the key is carefully protected.

  4. Create and copy the key.

    Copy the complete secret while it is displayed. The full value will not be shown again after you close the dialog.

Keep the key private.

Do not email it, paste it into chat, or include it in a screenshot. Revoke it immediately if it may have been exposed.

04

Return to the app

Add, test, and save the key.

  1. Open your Profile.

    Under Tools, select Profile, then expand AI Providers.

  2. Add Anthropic.

    Select Add provider, then Add next to Anthropic. If Anthropic is already listed, open its card.

  3. Paste the new key into Anthropic API Key.

    Paste only the complete key, without quotation marks or spaces before or after it.

  4. Select Test Key.

    Wait for Lakeview Lister to confirm that Anthropic accepted the credential.

  5. Choose Anthropic under Default AI if it should be the default for new runs.

    You can keep keys for other providers without changing your default.

  6. Select Save Profile.

    Lakeview Lister saves the credential securely on your computer.

Lakeview Lister handles the service connection. Choose the model and reasoning setting in the app; the key field does not need a model ID or URL.

You are finished when:

Test Key succeeds and, after you save the profile, the Anthropic card shows Key saved or Default.

05

Troubleshooting

Check expiration, workspace, and credits.

Anthropic returns 401 or says the key is invalid.

Confirm the key has not expired or been revoked. Recopy it without spaces, or create a replacement from the intended workspace.

The account has a paid Claude plan but API requests fail.

Open Anthropic Console Billing and buy API usage credits. Claude chat plan billing does not provide an API balance.

The Console balance is empty.

Purchase usage credits or review a failed auto-reload payment. Test the key again after the API balance updates.

The key exists in the wrong workspace.

Create a new key inside the workspace that should own Lakeview Lister usage, then update and retest the app.

Test Key says a model is unavailable.

Confirm the workspace has an active API credit balance and access to the model selected in Lakeview Lister, then test again.

The key may have been exposed.

Revoke it immediately in Anthropic Console, create a replacement, and update Lakeview Lister.
