API Documentation

Welcome to the NextGenDeepAI API documentation. Our API allows you to integrate state-of-the-art language models directly into your applications with ease.

Authentication

All API requests require a valid API key. You can generate and manage your API keys from the Dashboard.

How to get an API Key

Headers

Name	Value	Description
Content-Type	application/json	Required
X-API-Key	<your_api_key>	Your unique API key

Body Parameters

Parameter	Type	Description
prompt	string	The input text for the model.

Available Models

We support a variety of open-source small language models optimized for different use cases.

Model Name	Parameters	Context Length	Best For
qwen:0.5b	0.5B	32k	General purpose, extremely fast inference, low latency.
llama3	8B	8k	High quality reasoning, creative writing, complex tasks.
mistral	7B	8k	Balanced performance, strong instruction following, coding.
gemma	2B / 7B	8k	Lightweight, efficient, Google's open model family.

Code Examples

Curl

curl -X POST https://nextgendeepai.com/api/llm/v1/generate \
-H "Content-Type: application/json" \
-H "X-API-Key: YOUR_API_KEY" \
-d '{
  "model": "qwen:0.5b",
  "prompt": "Explain quantum computing",
  "stream": false
}'

Python

import requests

url = "https://nextgendeepai.com/api/llm/v1/generate"
headers = {
    "Content-Type": "application/json",
    "X-API-Key": "YOUR_API_KEY"
}
data = {
    "model": "qwen:0.5b",
    "prompt": "Explain quantum computing",
    "stream": False
}

response = requests.post(url, json=data, headers=headers)
print(response.json())

        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
        System.out.println(response.body());
