What you will finish with
One DeepSeek API key
Use this developer key for DeepSeek requests made by Lakeview Lister.
Before you start
Check what you need.
- An account with DeepSeek’s developer API service.
- Permission to create API keys and manage API usage for that account or workspace.
- Lakeview Lister installed so you can enter and test the key.
Developer account
Open the DeepSeek API console.
- Open DeepSeek Platform
Go to platform.deepseek.com ↗ and create or sign in to a developer account.
- Use the API platform
The API Keys and Top up controls are in DeepSeek Platform; a consumer chat sign-in by itself does not supply a key.
Prepare API usage
Check your API balance.
- Review the balance
Check the API balance in DeepSeek Platform before you run Draft Builder.
- Top up if needed
Use the platform’s Top up control when the balance is insufficient for paid API requests. Review its current prices and limits.
DeepSeek documents HTTP 402 as an insufficient-balance response. If key testing succeeds but a draft fails, check the platform balance.
Generate the credential
Create and copy the API key.
- Open API Keys
Go to the official DeepSeek API Keys page ↗.
- Create a key
Create a dedicated key for Lakeview Lister and copy the complete value.
If it is exposed, revoke it in the provider console and create a replacement. Do not send it to support.
Return to Lakeview Lister
Add and test the key.
- Open Profile
In Lakeview Lister, open Tools → Profile → AI Providers.
- Add the provider
Select Add provider, choose DeepSeek, and expand its card under Your providers.
- Enter DeepSeek API Key
Paste the complete API key into this field without spaces or quotation marks.
- Test and save
Select Test Key, then Save Profile. Choose the provider as your default if you want future runs to start with it.
If a request fails
Check the account and key.
The API returns 402.
DeepSeek identifies this as insufficient balance. Add funds under Top up, then retry the draft.
The app rejects the key.
Confirm you copied a Platform API key, not a chat credential; remove any leading or trailing spaces.
Requests are limited.
Review DeepSeek Platform’s current rate limits and account status.
