Gemini API through one OpenAI-compatible key

Gemini models on Evrona and their prices

This table is built from the live Evrona catalog. Text models are priced per million input and output tokens; the Model ID under each name starts with google/ and goes into the model field of your request.

Accounting inside the service is in USD; EUR prices are recalculated at the current rate and may change.

How to get a Gemini API key

1. Sign up

   Create an Evrona account with your email — it takes about a minute.

2. Top up with a code

   Buy a top-up code in the store and redeem it in your dashboard. The amount lands on your prepaid balance right away.

3. Create a key

   Create an ev-… API key in your dashboard. It works with Gemini models and the rest of the catalog straight away, and you can put a spending cap on it.

Gemini API request example

The gateway speaks the OpenAI API: set the base URL to https://evrona.ru/v1, use your Evrona key and pick a Model ID from the table. The example uses google/gemini-4-argon.

curl https://evrona.ru/v1/chat/completions \
  -H "Authorization: Bearer ev-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/gemini-4-argon",
    "messages": [
      {
        "role": "user",
        "content": "Hi! Tell me about yourself in two sentences."
      }
    ]
  }'

from openai import OpenAI

client = OpenAI(
    base_url="https://evrona.ru/v1",
    api_key="ev-YOUR_KEY",
)

completion = client.chat.completions.create(
    model="google/gemini-4-argon",
    messages=[
        {
            "role": "user",
            "content": "Hi! Tell me about yourself in two sentences."
        }
    ],
)
print(completion.choices[0].message.content)

Gemini API pricing and payment

The lighter Flash models are the usual pick for high-volume, latency-sensitive work such as classification, extraction and short chatbot replies, while Pro models are chosen for long documents and multi-step reasoning. Every request is billed on actual usage at the rates listed.

• Prepaid balance: top up first, then send requests — no subscription and no monthly fee.
• You top up in rubles with a top-up code that you redeem in your dashboard.
• You pay only for actual usage at the rates in the table, and every request shows up in your history.
