OpenAI

GPT models via the official OpenAI API — full model catalog and API features

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: ChatGPT Plus ($20/mo chat subscription) does not include API access. API usage is billed separately on platform.openai.com — add a payment method under Settings → Billing

  1. Open the OpenAI Platform: platform.openai.com (this is different from chat.openai.com where you chat with ChatGPT)
  2. Sign up or log in with the same account you use for ChatGPT, or a separate work account
  3. Go to Settings → Billing and add a payment method if you have not already — the API is pay-as-you-go
  4. Open Settings → API keys (or use the link on this page)
  5. Click "Create new secret key"
  6. Name it "Airbox" and choose your default project
  7. Copy the secret key — OpenAI only shows it once
  8. Keep the key private; anyone with it can spend on your OpenAI account

Open OpenAI key page →

The key usually looks like: sk-… or sk-proj-…

Part 2 — Add your connection in Airbox

  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: openai
  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 "openai" listed under Connections

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:

  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"

Try it — send an email

Subject: (* @openai #summarize *)

Subject: @openai #extract

Short checklist

  • Get a Platform API key (not ChatGPT Plus alone)
  • Dashboard → + LLM provider → openai → paste sk-… key
  • Optional model override in the prompt (e.g. gpt-4.1)

What you get

  • Official api.openai.com endpoint
  • Full GPT model lineup available on your API account
  • Works with MCP tools attached to the inbox

Notes

  • See the ChatGPT page if you mainly think of yourself as a ChatGPT user — same connection, friendlier framing
