AWS Textract with Claude Example

This guide demonstrates how to use AWS Textract combined with Claude for powerful document processing.

Basic Setup

Here's how to combine AWS Textract's OCR capabilities with Claude:

from extract_thinker import Extractor, Contract, LLM, DocumentLoaderTextract
from typing import List
from pydantic import Field

class InvoiceContract(Contract):
    invoice_number: str = Field("Invoice number")
    invoice_date: str = Field("Invoice date")
    total_amount: float = Field("Total amount")
    lines: List[LineItem] = Field("List of line items")

# Initialize AWS Textract
extractor = Extractor()
extractor.load_document_loader(
    DocumentLoaderTextract(
        aws_access_key_id=os.getenv("AWS_ACCESS_KEY_ID"),
        aws_secret_access_key=os.getenv("AWS_SECRET_ACCESS_KEY"),
        region_name=os.getenv("AWS_REGION")
    )
)

# Configure Claude
llm = LLM(
    "anthropic/claude-3-haiku-20240307",
    api_key=os.getenv("ANTHROPIC_API_KEY")
)
extractor.load_llm(llm)

# Process document
result = extractor.extract("invoice.pdf", InvoiceContract)

Cost Optimization

AWS Textract pricing:

• Basic text detection: $1.50 per 1,000 pages (first 1M pages/month) $0.60 per 1,000 pages (over 1M pages/month)

• Tables: $15.00 per 1,000 pages (first 1M pages/month) $10.00 per 1,000 pages (over 1M pages/month)

Combined with Claude (via AWS Bedrock):

• Claude 3 Haiku: $0.00025 per 1K input tokens, $0.00125 per 1K output tokens

• Claude 3 Sonnet: $0.003 per 1K input tokens, $0.015 per 1K output tokens

Approximate cost per page (first 1M pages/month): - Basic text only: $0.0015 per page ($1.50/1000) - With tables: $0.0165 per page ($1.50/1000 + $15.00/1000) - Plus Claude costs (varies by token length and model choice)
