# OnlySq API — Free Access to 40+ AI Models

Get started

Working with OnlySq API2.0
==========================

Copy page

Only Sq is a dedicated team of programmers specializing in the development of API2.0, sites, bots and many scripts. The team focuses on integrating advanced neural network models into their API offerings, enhancing the functionality and performance of their services. They prioritize user experience and efficient data processing, ensuring that their API is both powerful and easy to use for developers.

The API is free, with RPM limits based on account level.

Starting with patch 4.0.1 (November 29, 2025), every request to `v2/imagen` must have Authorization header

JSON

{"Authorization": "Bearer apikey"}

Use your personal API key from [Go to your profile](https://my.onlysq.ru/)
. Key `openai` no longer works.

You can check your current personal limits here: [https://my.onlysq.ru/usage](https://my.onlysq.ru/usage)

SDKs
----

OnlySq supports calls via OpenAI SDK libraries as the primary way of accessing API, providing advanced models for the user and ease of use for the developer. To get started, please see the installation methods and code snippets below.

PythonTypeScript

pip install -U openai

from openai import OpenAI

client = OpenAI(

base\_url="https://api.onlysq.ru/ai/openai",

api\_key="YOUR\_API\_KEY",

)

completion = client.chat.completions.create(

model="gpt-4o-mini",

messages=\[\
\
{\
\
"role": "user",\
\
"content": "Say 5 short facts about AI.",\
\
},\
\
\],

)

print(completion.choices\[0\].message.content)

### Example response (via the Python SDK)

Response

    Here are five short facts about AI:  
    
    1. **AI Learns from Data** – AI systems improve by analyzing large amounts of data, identifying patterns, and making predictions.          
    2. **Narrow vs. General AI** – Most AI today is "narrow" (task-specific), while "general AI" (human-like reasoning) is still theoretical.  
    3. **AI Powers Everyday Tech** – Virtual assistants (Siri, Alexa), recommendations (Netflix, Spotify), and spam filters all use AI.        
    4. **Ethical Concerns Exist** – AI raises issues like bias in algorithms, job displacement, and privacy risks.  
    5. **AI is Evolving Fast** – Breakthroughs in deep learning and generative AI (like ChatGPT) are rapidly advancing the field.
