Custom Claude Key

Enterprise Feature

This feature is only available in Enterprise plan. Learn More

You can configure your own Anthropic (Claude) API key to power AI features in your project. This routes Anthropic-model requests through your own Anthropic account so:

  • Billing — the underlying token cost is charged to your Anthropic account directly, not Unlayer's. Unlayer's percentage on top still applies — it covers routing, orchestration, and observability on top of the model call.
  • Rate limits — your Anthropic account's rate limits apply, not Unlayer's shared pool.

Setting up your custom key​

  1. Open your project in Console.
  2. Navigate to Premium Features.
  3. Paste your Anthropic API key into the Anthropic API Key input.
  4. Click Save Key.

The key is validated against Anthropic before being stored. Once saved, every AI feature that resolves to an Anthropic model uses this key instead of Unlayer's default.

What this affects​

Your custom key powers Anthropic-routed AI requests. In particular, Claude is Unlayer's default preferred model for template generation in the AI Assistant — the heaviest design-quality work (full template generation, multi-row restyles, anything where visual taste matters) routes to Claude by default. With a custom key, those calls bill to your Anthropic account.

OpenAI requests are unaffected — see Custom OpenAI Key — and image generation runs on Gemini — see Custom Gemini Key.
