What Is CometAPI?
CometAPI is a unified AI API aggregator. Instead of signing up separately for OpenAI, Anthropic, Google, xAI, DeepSeek – and managing 5 API keys, 5 bills, 5 rate limits – you sign up once for CometAPI, get 1 API key, and access 500+ models through 1 endpoint.
It is OpenAI-compatible. That means if your app already uses OpenAI API, you only change 2 lines: base_url and api_key – and you instantly get access to Claude, Gemini, Grok, and everything else, without rewriting your code.
CometAPI also gives you Playground 2.0 / Decision Desk – compare 3 models on the same prompt, see quality, latency and cost side-by-side, and get an AI recommendation which model to use.
