If you’ve ever built an AI-powered product, you know the drill: one API key for OpenAI, another for Anthropic, a separate billing account for Google Gemini, yet another for Midjourney — and suddenly your architecture is a spaghetti of credentials, rate limits, and invoices.
CometAPI exists to end that chaos. It’s a developer-centric API aggregation platform that gives you a single endpoint, a single API key, and a single invoice — covering over 500 AI models from every major provider.
- 500+ AI Models Available
- 10k+ Active Developers
- 20–40% Cost Savings
- <400ms Avg. Response Time
- 99.9% Service Uptime SLA
What exactly is CometAPI?
CometAPI is an AI infrastructure platform operated by EFOXTech Limited (incorporated in Hong Kong, 2024). Its core promise is deceptively simple: instead of integrating separately with OpenAI, Anthropic, Google, Midjourney, and dozens of others, developers send all their requests to api.cometapi.com/v1 — the same endpoint, every time — and specify the model they want by name.
The platform is OpenAI-compatible, meaning if your existing code already uses the OpenAI Python or Node SDK, switching to CometAPI requires changing exactly two lines: the base_url and the API key. No rewrite, no migration pain.
