Register once and receive a single API key tied to your account. Use the Base URL with clients that support a custom OpenAI-compatible Chat Completions endpoint. Your key and Base URL stay the same as you add those clients.

Choose a stable public model ID from the live catalog. Asterionyx keeps internal routing separate, so approved routing changes do not alter your credentials or Base URL.

You decide the amount and the timing.
- Pay as you go
Every request draws from your prepaid Credits — you only ever spend what you actually use.
- No subscriptions
No monthly fees and no automatic charges. Recharge whenever it suits you, never on a schedule.
- Credits don’t expire
Credits remain available while your account is active and in good standing. Unpaid orders expire; Credit balances do not vanish with the order window.
- Clear usage records
The portal shows remaining Credits and a usage summary with a last-updated time, rather than implying instant per-call detail.

Target audiences
Asterionyx is a prepaid, OpenAI-compatible API with a live Model Catalog and setup guides for popular clients.
Technical users
Integrate with one customer API key, one Base URL, and published model IDs. Use a client that can target a custom Chat Completions endpoint.
Non-technical users
Connect tools you already use — Dify, Chatbox, Cherry Studio, Open WebUI, and other documented clients — without building a custom integration.
Strategic audiences
Plan against prepaid Credits, the live catalog, and a portal usage summary. Recharge when you choose; nothing renews in the background.
