OpenRouter

Billing: Add credits at openrouter.ai — you pick models per request via the model name

1. Visit openrouter.ai and sign up
2. Add credits or link billing under your account settings
3. Go to Keys and create an API key
4. Copy the key (often starts with sk-or-)
5. Note the model id you want (e.g. anthropic/claude-sonnet-4) — you will enter it when Airbox asks for a model

Open OpenRouter key page →

The key usually looks like: sk-or-…

1. Sign in at the Airbox dashboard (airbox.fyi/dashboard)
2. In the Connections card, click "+ LLM provider"
3. When asked for the provider type, enter: openrouter
4. When asked for your API key, paste the key you copied — it is encrypted and never shown again
5. When asked for a model, press Enter to accept the default or type a model name (see this page's default)
6. You should now see "openrouter" listed under Connections
7. 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

Your Airbox address does not use a connection until you attach one:

1. In the Inboxes card, find your Airbox address
2. Click the gear icon (⚙) on that address to open routing settings
3. Under "AI, LLM or MCP provider", choose the connection you just added from the dropdown
4. Leave "Email a reply back" checked if you want results in your inbox (recommended)
5. Click "Save"
