textract-io

Structured Text Extraction for Scientific & Factual Data

textract_io is a Python package designed to extract structured key information from scientific or factual text inputs. It leverages pattern matching and retry mechanisms to ensure accurate, reliable responses—ideal for generating summaries, extracting data, or categorizing text based on user prompts. Perfect for processing pre-extracted textual data from multimedia sources to produce concise, structured outputs for research, reporting, or database entry.

🚀 Features

• Pattern-based extraction: Uses regex patterns to enforce structured output.
• LLM7 integration: Defaults to ChatLLM7 (from langchain_llm7) for extraction tasks.
• Flexible LLM support: Easily swap with any LangChain-compatible LLM (OpenAI, Anthropic, Google, etc.).
• Error handling: Robust retry logic and clear error messages.
• Environment-aware: Uses LLM7_API_KEY from environment variables or direct API key input.

📦 Installation

pip install textract_io

🔧 Usage

Basic Usage (Default LLM7)

from textract_io import textract_io

response = textract_io(user_input="Your text here...")
print(response)  # List of extracted data matching the pattern

Custom LLM Integration

Replace the default ChatLLM7 with any LangChain-compatible LLM (e.g., OpenAI, Anthropic, Google):

OpenAI Example

from langchain_openai import ChatOpenAI
from textract_io import textract_io

llm = ChatOpenAI()
response = textract_io(user_input="Your text here...", llm=llm)

Anthropic Example

from langchain_anthropic import ChatAnthropic
from textract_io import textract_io

llm = ChatAnthropic()
response = textract_io(user_input="Your text here...", llm=llm)

Google Generative AI Example

from langchain_google_genai import ChatGoogleGenerativeAI
from textract_io import textract_io

llm = ChatGoogleGenerativeAI()
response = textract_io(user_input="Your text here...", llm=llm)

---

🔑 API Key Configuration

• Default: Uses LLM7_API_KEY from environment variables.
• Manual Override: Pass the API key directly:

  response = textract_io(user_input="Your text...", api_key="your_llm7_api_key")

• Free API Key: Register at LLM7 Token to get started.

---

📝 Parameters

Parameter	Type	Description
user_input	str	The input text to process.
api_key	Optional[str]	LLM7 API key (defaults to LLM7_API_KEY environment variable).
llm	Optional[BaseChatModel]	Custom LangChain LLM (e.g., ChatOpenAI, ChatAnthropic). Defaults to ChatLLM7.

---

📊 Rate Limits

• LLM7 Free Tier: Sufficient for most use cases.
• Upgrade: Use your own API key or environment variable for higher limits.

---

🔄 Error Handling

• If extraction fails, raises RuntimeError with a descriptive message.
• Retries internally to improve reliability.
