Grok API: get a key and call Grok models

Grok models on Evrona and their prices

This table lists the x-ai/ models in the Evrona catalog, priced per million input and output tokens. To call one, put its Model ID into the model field.

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

How to get a Grok 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 Grok models and the rest of the catalog straight away, and you can put a spending cap on it.

Grok 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 x-ai/grok-4.6.

curl https://evrona.ru/v1/chat/completions \
  -H "Authorization: Bearer ev-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "x-ai/grok-4.6",
    "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="x-ai/grok-4.6",
    messages=[
        {
            "role": "user",
            "content": "Hi! Tell me about yourself in two sentences."
        }
    ],
)
print(completion.choices[0].message.content)

Grok API pricing and payment

Grok versions differ in price and capabilities, so compare them in the table and try them on your own prompts before committing. Billing follows the actual input and output tokens of each request, with no monthly fee.

• 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.
