pdf-craft-sdk 0.3.0

A Python SDK for PDF Craft API

PDF Craft SDK

A Python SDK for interacting with the PDF Craft API. It simplifies the process of converting PDFs to Markdown or EPUB by handling authentication, task submission, and result polling.

Installation

You can install the package from PyPI:

pip install pdf-craft-sdk

Usage

Basic Usage

The SDK provides a high-level convert method that handles everything for you (submission + polling).

from pdf_craft_sdk import PDFCraftClient, FormatType

# Initialize the client
client = PDFCraftClient(api_key="YOUR_API_KEY")

# Convert a PDF to Markdown and wait for the result
try:
    pdf_url = "cache://your-pdf-file.pdf"
    download_url = client.convert(pdf_url, format_type=FormatType.MARKDOWN)
    print(f"Conversion successful! Download URL: {download_url}")
except Exception as e:
    print(f"An error occurred: {e}")

Advanced Usage

If you prefer to handle the steps manually or asynchronously:

from pdf_craft_sdk import PDFCraftClient, FormatType

client = PDFCraftClient(api_key="YOUR_API_KEY")

# 1. Submit task
task_id = client.submit_conversion(
    pdf_url="cache://your-pdf-file.pdf",
    format_type=FormatType.MARKDOWN
)
print(f"Task submitted. ID: {task_id}")

# 2. Wait for completion explicitly
try:
    download_url = client.wait_for_completion(task_id, format_type=FormatType.MARKDOWN)
    print(f"Download URL: {download_url}")
except Exception as e:
    print(f"Conversion failed or timed out: {e}")

Configuration

The convert and wait_for_completion methods accept optional configuration for polling behavior:

• max_wait_ms: Maximum time (in milliseconds) to wait for the conversion. Default is 7200000 (2 hours).
• check_interval_ms: Initial polling interval (in milliseconds). Default is 1000 (1 second).
• max_check_interval_ms: Maximum polling interval (in milliseconds). Default is 5000 (5 seconds).
• backoff_factor: Multiplier for increasing interval after each check, or PollingStrategy enum. Default is PollingStrategy.EXPONENTIAL (1.5).

Polling Strategies

You can use PollingStrategy enum for backoff_factor:

• PollingStrategy.EXPONENTIAL (1.5): Default. Starts fast, slows down.
• PollingStrategy.FIXED (1.0): Polls at a fixed interval.
• PollingStrategy.AGGRESSIVE (2.0): Doubles the interval each time.

from pdf_craft_sdk import PollingStrategy

# Example: Stable Polling (Every 3 seconds)
download_url = client.convert(
    pdf_url="...", 
    check_interval_ms=3000,
    max_check_interval_ms=3000,
    backoff_factor=PollingStrategy.FIXED
)

# Example: Long Running Task (Start slow, check infrequently)
download_url = client.convert(
    pdf_url="...", 
    check_interval_ms=5000,
    max_check_interval_ms=60000, # 1 minute
    backoff_factor=2.0 # or PollingStrategy.AGGRESSIVE
)
