OpenAI-compatible AI API
Api.Airforce exposes an OpenAI-compatible endpoint — and the Anthropic Messages API — behind one base URL. Point the SDK you already use at https://api.airforce/v1, swap the key, and call 200+ models across providers with pay-as-you-go pricing and a free tier.

Frequently asked questions
- What does "OpenAI-compatible" mean here?
- Api.Airforce implements the same HTTP API and request/response shape as OpenAI’s Chat Completions endpoint (/v1/chat/completions). Any client or library built for the OpenAI API works unchanged — you only change the base URL to https://api.airforce/v1 and use your Airforce key.
- How do I switch an existing OpenAI integration over?
- Set the base URL to https://api.airforce/v1 and swap the API key. Keep using the official OpenAI SDK; just pick a model id from our catalog. No other code changes are needed.
- Does the Anthropic API work too?
- Yes. The same key also speaks the Anthropic Messages API (/v1/messages), so the official Anthropic SDK works by pointing baseURL at https://api.airforce. You get both protocols behind one endpoint and one key.
- Which tools work out of the box?
- Anything that supports an OpenAI-compatible endpoint — Cursor, Cline, Claude Code, Aider, Continue, SillyTavern, Open WebUI, LibreChat and many more. There are step-by-step setup guides for 25+ tools in the docs.
- Is there a free tier?
- A free account needs no credit card and can call the models on the free tier at $0; premium models are pay-as-you-go. See the pricing page for details.
