One key to every model
Evrona is an OpenAI-compatible gateway to language and generative models from many providers: OpenAI, Anthropic, Google, DeepSeek, xAI and more. You get one API key and one base URL evrona.ru/v1 — and switch to any model just by changing its name in the request. Code written for the official OpenAI SDK works as is.
We built Evrona for developers and teams who are tired of juggling a dozen foreign accounts and cards. One prepaid balance in US dollars; top it up in rubles — no VPN or foreign card needed. Every request is charged by actual token usage and shows up in your history, so the project budget stays under control.
How it works
Your code talks to a single endpoint. Evrona routes by model name and charges one shared balance.
OpenAI SDK, unchanged
base_url = "evrona.ru/v1" model = "anthropic/claude-fable-5.1"

How we work
Compatibility over a new API
No custom protocol. Change base_url and the key — your code, SDKs and clients stay the same.
Pay for what you use
No subscriptions or plans. Every request is billed by actual tokens and shows up in your history.
No barriers to entry
Top up in rubles, no VPN or foreign card. Sign-up and first request in a couple of minutes.
Your requests are not our data
Request and response bodies are never stored. We keep metadata only: time, model, tokens and cost.
