DeepSeek API: get a key, check prices, send a request

DeepSeek models on Evrona and their prices

These are the DeepSeek models currently enabled in the Evrona catalog. Input and output are priced separately per million tokens; pass the Model ID shown under each name as the model parameter.

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

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

DeepSeek 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 deepseek/deepseek-v4.1-flash.

curl https://evrona.ru/v1/chat/completions \
  -H "Authorization: Bearer ev-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek/deepseek-v4.1-flash",
    "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="deepseek/deepseek-v4.1-flash",
    messages=[
        {
            "role": "user",
            "content": "Hi! Tell me about yourself in two sentences."
        }
    ],
)
print(completion.choices[0].message.content)

DeepSeek API pricing and payment

Teams usually reach for DeepSeek when a job burns through a lot of tokens — support bots, document processing, writing and reviewing code. A request costs its input plus output tokens at the rates above, with no subscription or minimum spend.

• 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.
