Markifact allows you to use your own API keys from leading AI providers. This gives you more control over your AI usage and significantly reduces your Markifact credit consumption.

​
Supported AI Providers

We currently support four AI providers:
  • OpenAI
  • Google Gemini
  • Anthropic
  • DeepSeek

​

​
How It Works

When you configure your own API key:
  1. AI requests go through your account — Markifact sends AI requests using your API key, and usage is billed directly by the provider to your account.
  2. You control the models — Use models supported by Markifact and available to your provider account, including the latest supported releases.
  3. Your data, your terms — Requests are subject to your agreement with the AI provider, not Markifact’s.
Markifact securely stores your API keys using encryption. We never log or store the content of your AI requests.

​
Credit Savings

Using your own API keys significantly reduces Markifact credit costs:

​
AI Nodes (0 Credits)

When using your own API keys, all standard AI nodes consume 0 credits:
  • AI Ask — 0 credits
  • AI Structure — 0 credits
  • AI Analyze Data — 0 credits
  • AI Analyze Image — 0 credits
  • AI Generate Image — 0 credits
  • AI Edit Image — 0 credits

​
AI Agents (1 Credit Flat)

Agent nodes have a flat credit cost regardless of complexity: This flat rate applies no matter how many tools the agent uses or how long it takes to complete the task. DeepSeek BYOK is currently available for DeepSeek V4 Pro and DeepSeek V4 Flash in AI Agents. Both models are text-only and use DeepSeek’s default thinking mode.

​
Comparison Example

💡 Tip: If you run AI-heavy workflows frequently, using your own API keys can result in substantial credit savings.

​
Switching Between Your Keys and Markifact

When you add your own API key for a provider, all AI nodes will automatically use your key instead of Markifact’s built-in AI. To switch back to using Markifact’s AI:
  1. Go to the Connections page
  2. Find the API key connection you want to remove
  3. Delete the connection
Once deleted, AI nodes will default back to Markifact’s built-in AI (and credit costs will apply as normal).
💡 If you have multiple API keys for the same provider, Markifact will use the most recently added key.

​
FAQ

Yes, but significantly fewer. You still need credits for:
  • Workflow runs (1 credit per run)
  • AI Agent and Task Agent nodes (1 credit flat each)
  • Other non-AI nodes (Sheets, Slides, Google Ads, etc.)
The main savings come from AI nodes becoming free (0 credits).
Yes. Your API key is encrypted and stored securely. For security, API keys are never returned to the frontend after saving—they cannot be viewed or edited, only deleted. We never log the content of your AI requests.
Yes. You can add multiple API keys for the same provider. Markifact will automatically use the most recently added key for that provider.
Workflows using that key will fail on AI nodes. You’ll need to delete the old connection and add a new one with a valid API key. Other nodes in the workflow will continue to work.
Rate limits are determined by your AI provider account, not Markifact. If you hit rate limits, you’ll see errors from the provider. Consider upgrading your plan with the provider or spreading requests across time.
You can use any model supported by your provider and available in Markifact’s AI nodes. DeepSeek keys currently work with DeepSeek V4 Pro and DeepSeek V4 Flash in AI Agents. We regularly update our model list to include the latest releases.
