NexKey Get a key
Demo / In Development — demo keys only, no live billing yet

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.

Use it in one request

    "messages": [{"role": "user", "content": "Hello!"}]
  }'
