OpenRouter
One API key for many models — OpenAI, Anthropic, Meta, and more
No coding required. If you have never used an API key before, follow the walkthrough below step by step. Developers can skip to Quick reference at the bottom
Part 1 — Get your API key
Billing: Add credits at openrouter.ai — you pick models per request via the model name
- Visit openrouter.ai and sign up
- Add credits or link billing under your account settings
- Go to Keys and create an API key
- Copy the key (often starts with sk-or-)
- Note the model id you want (e.g. anthropic/claude-sonnet-4) — you will enter it when Airbox asks for a model
The key usually looks like: sk-or-…
Part 2 — Add your connection in Airbox
- Sign in at the Airbox dashboard (airbox.fyi/dashboard)
- In the Connections card, click "+ LLM provider"
- When asked for the provider type, enter: openrouter
- When asked for your API key, paste the key you copied — it is encrypted and never shown again
- When asked for a model, press Enter to accept the default or type a model name (see this page's default)
- You should now see "openrouter" listed under Connections
- When asked for a model, enter an OpenRouter model id such as openai/gpt-4.1 or anthropic/claude-sonnet-4
Open the dashboard in a new tab if you want to follow along
Part 3 — Route your inbox
Your Airbox address does not use a connection until you attach one:
- In the Inboxes card, find your Airbox address
- Click the gear icon (⚙) on that address to open routing settings
- Under "AI, LLM or MCP provider", choose the connection you just added from the dropdown
- Leave "Email a reply back" checked if you want results in your inbox (recommended)
- Click "Save"
Try it — send an email
