Ofox is an aggregated large language model API platform built for developers. A single API key grants you access to 100+ mainstream large language models, including GPT, Claude, Gemini, DeepSeek, Qwen, and GLM. The platform provides three integration protocols: OpenAI-compatible, Anthropic native, and Gemini native, so you can integrate directly using the SDKs you already know (specific protocol support for each model is determined by the model itself). The platform’s in-house developed gateway features built-in multi-model load balancing and automatic failover to guarantee stable API calls; it operates on a pay-as-you-go billing model and supports a variety of payment methods. It is perfect for developers and teams that need to flexibly switch between multiple models without the hassle of managing multiple accounts and API keys.
