kawn.ai 0.1.0

The official Python SDK for the kawn AI API

misraj.ai Python SDK

The official Python client for interacting with the misraj.ai API.

Installation

pip install kawn.ai

Setup

Set your API key as an environment variable (recommended):

export MISRAJ_API_KEY="your-api-key"

Architecture Usage

The kawn.ai SDK is designed with decoupled services. You create a core HTTP Client first, and pass it to whatever specific service you need. This keeps the library robust and easy to extend.

1. Synchronous Usage

from kawn import KawnClient
from kawn.services import EmbeddingService, OCRService

# The client automatically picks up the MISRAJ_API_KEY environment variable.
client = Client()

# Initialize our decoupled services using the core client transport
embeddings_service = EmbeddingService(client)
ocr_service = OCRService(client)

# Text Embeddings
response = embeddings_service.create(inputs="Hello, kawn.ai!")
print(response.data[0].embedding)

# Batch Embeddings
batch_response = embeddings_service.create(inputs=[
    "This is the first sentence.",
    "This is the second sentence."
])
print(batch_response.data)

# Basser OCR: Single File Processing (Supports Images and PDFs)
ocr_res = ocr_service.process_file(file_path="document.pdf")
print(ocr_res)

# Basser OCR: Batch File Processing
batch_ocr_res = ocr_service.process_batch(file_paths=[
    "document1.png",
    "document2.pdf"
])

for res in batch_ocr_res.successful_results:
    print(res)

2. Asynchronous Usage

For high-performance applications, use the AsyncClient and async services.

import asyncio
from kawn import AsyncKawnClient
from kawn.services import AsyncEmbeddingService, AsyncOCRService

async def main():
    # You can also pass credentials explicitly if bypassing env variables
    async with AsyncClient(api_key="your-api-key") as client:
        
        # Initialize Async services
        embed_service = AsyncEmbeddingService(client)
        ocr_service = AsyncOCRService(client)

        batch_embed_res = await embed_service.create(
            inputs=["Concurrency is fast!", "Async batching is optimal."]
        )
        print(batch_embed_res)

        # Basser OCR Async Batch Processing
        batch_ocr_res = await ocr_service.process_batch(
            file_paths=["receipt_amount.png", "invoice.pdf"]
        )
        
        for r in batch_ocr_res.successful_results:
            print(r)

if __name__ == "__main__":
    asyncio.run(main())

Utilities & PDF Processing

The OCRService inherently supports uploading both images and multi-page PDF files directly. There is generally no need to manually convert or split your PDFs before using the OCR API.

However, if you require more granular control—such as processing individual pages, setting a specific zoom factor, or rendering files to images offline before sending them—you can use the SDK's built-in PDF helper:

from misraj.utils.pdf import convert_pdf_to_images

# Processes the PDF into separate images in parallel and saves them locally
image_files = convert_pdf_to_images(
    pdf_content="report.pdf", 
    zoom=4, 
    output_folder="./processed_pages"
)

Error Handling

from kawn import KawnClient
from kawn import KawnAPIError, AuthenticationError, RateLimitError
from kawn.exceptions import ProcessingFailedError
from kawn.services import OCRService

try:
    client = KawnClient()
    ocr = OCRService(client)
    ocr.process_file("broken_file.jpg")
except AuthenticationError as e:
    print("Invalid API Key!", e)
except RateLimitError as e:
    print("Too many requests, slow down!", e)
except ProcessingFailedError as e:
    print("OCR Processing failed on the server!", e)
except KawnAPIError as e:
    print(f"Generic server error: {e}")
