Bring Your Own Key
Promptmark now supports direct connections to OpenAI and Anthropic alongside OpenRouter. Connect your own provider account and Promptmark automatically routes requests to the right place.
What’s new
- Direct OpenAI connection – Add your OpenAI API key in Settings for direct access to GPT models. Get one from platform.openai.com/api-keys.
- Direct Anthropic connection – Add your Anthropic API key in Settings for direct access to Claude models.
- Automatic provider routing – When you have a direct key, requests to that provider’s models skip OpenRouter entirely. Lower latency, no middleman, direct billing.
- Provider indicators – After a response completes, you see which provider served it: “via OpenAI”, “via Anthropic”, or “via OpenRouter”.
- OpenRouter fallback – Models from other providers (Google, Meta, Mistral) still route through OpenRouter automatically.
For API integrators
The send_message MCP tool now supports all three providers. It automatically uses the best available key for the selected model – no changes needed on your end.
