Installation

pip install ai-lls-lib

For development:

git clone https://github.com/augmenting-integrations/ai-lls-lib.git
cd ai-lls-lib
uv sync --all-extras

Quick Start

Single Phone Verification

from ai_lls_lib import PhoneVerifier, DynamoDBCache

cache = DynamoDBCache(table_name="phone-cache")
verifier = PhoneVerifier(cache)

result = verifier.verify("[phone]")
print(f"Line type: {result.line_type}")  # mobile, landline, voip, unknown
print(f"DNC: {result.dnc}")              # True/False
print(f"Cached: {result.cached}")        # True/False

Bulk Processing

from ai_lls_lib import BulkProcessor, PhoneVerifier, DynamoDBCache

cache = DynamoDBCache(table_name="phone-cache")
verifier = PhoneVerifier(cache)
processor = BulkProcessor(verifier)

csv_text = "name,phone\nJohn,[phone]\nJane,[phone]"
results = processor.process_csv(csv_text)

# Generate results CSV with added columns
results_csv = processor.generate_results_csv(csv_text, results)

Streaming Large Files

from ai_lls_lib import BulkProcessor, PhoneVerifier, DynamoDBCache

cache = DynamoDBCache(table_name="phone-cache")
verifier = PhoneVerifier(cache)
processor = BulkProcessor(verifier)

csv_lines = open('large_file.csv').readlines()
for batch in processor.process_csv_stream(csv_lines, batch_size=100):
    print(f"Processed batch of {len(batch)} phones")

Custom Verification Providers

from ai_lls_lib import PhoneVerifier, DynamoDBCache
from ai_lls_lib.providers import StubProvider

# Use stub provider for testing (deterministic results)
cache = DynamoDBCache(table_name="phone-cache")
provider = StubProvider()
verifier = PhoneVerifier(cache, provider=provider)
