Python SDK — Getting Started

The Expunct Python SDK provides a type-safe client for the Expunct API, with both synchronous and asynchronous interfaces.

Requirements

Python 3.10 or later
Dependencies: httpx, pydantic

Installation


pip install pii-redactor-sdk

Quick Example

Synchronous


from pii_redactor_sdk import PiiRedactor
 
client = PiiRedactor(api_key="pk_live_...")
result = client.redact.text(
    text="John Smith's email is john@example.com",
)
print(result.redacted_text)
# "[PERSON]'s email is [EMAIL_ADDRESS]"

Asynchronous


import asyncio
from pii_redactor_sdk import AsyncPiiRedactor
 
async def main():
    client = AsyncPiiRedactor(api_key="pk_live_...")
    result = await client.redact.text(
        text="John Smith's email is john@example.com",
    )
    print(result.redacted_text)
 
asyncio.run(main())

Configuration

Parameter	Type	Default	Description
`api_key`	`str`	required	Your API key (starts with `pk_live_` or `pk_test_`)
`base_url`	`str`	`https://api.pii-redactor.dev`	API base URL
`timeout`	`float`	`30.0`	Request timeout in seconds
`max_retries`	`int`	`3`	Maximum retry attempts for transient failures


client = PiiRedactor(
    api_key="pk_live_...",
    base_url="https://api.pii-redactor.dev",
    timeout=60.0,
    max_retries=5,
)

Convenience Methods

The SDK provides shorthand methods for the most common operations:


# Redact text inline
result = client.sanitize_text("Call me at 555-0123")
 
# Redact a file (returns a job)
job = client.sanitize_file("s3://my-bucket/document.pdf")
 
# Redact content at a URI (returns a job)
job = client.sanitize_uri("https://example.com/page")
