Demo / In Development — demo keys only, no live billing yet
One API key.
One API key.
Every model.
NexKey is a tech platform for developers: generate one key, call any AI model behind it, and pay only for what you actually use. No subscriptions, no per-model signups.
Models behind one key
Route to different models with the same key and the same request shape. Model names below are examples for the demo.
nexkey/llama-3.1-8b
Fast, cheap, general chat. Good default for most apps.
nexkey/qwen-2.5-72b
Strong reasoning and long context for harder tasks.
nexkey/gemma-3-27b
Balanced quality and speed for production workloads.
API keys
Generate a demo key below. Demo keys are created in your browser only — they are not stored, not billed, and do not call a live model.
