Usage

Basic Usage

from isbn_transformer import isbn_transformer

user_input = "Your raw ISBN data here"
response = isbn_transformer(user_input)
print(response)

Using a Custom LLM

You can use any LLM compatible with LangChain. Here are examples using different LLMs:

Using OpenAI

from langchain_openai import ChatOpenAI
from isbn_transformer import isbn_transformer

llm = ChatOpenAI()
response = isbn_transformer(user_input, llm=llm)
print(response)

Using Anthropic

from langchain_anthropic import ChatAnthropic
from isbn_transformer import isbn_transformer

llm = ChatAnthropic()
response = isbn_transformer(user_input, llm=llm)
print(response)

Using Google

from langchain_google_genai import ChatGoogleGenerativeAI
from isbn_transformer import isbn_transformer

llm = ChatGoogleGenerativeAI()
response = isbn_transformer(user_input, llm=llm)
print(response)

Using LLM7 API Key

By default, the package uses the LLM7 API. You can pass your API key via an environment variable or directly in the function call.

Using Environment Variable

import os
from isbn_transformer import isbn_transformer

os.environ["LLM7_API_KEY"] = "your_api_key"
response = isbn_transformer(user_input)
print(response)

Directly Passing API Key

from isbn_transformer import isbn_transformer

response = isbn_transformer(user_input, api_key="your_api_key")
print(response)

Parameters

• user_input (str): The user input text to process.
• llm (Optional[BaseChatModel]): The LangChain LLM instance to use. If not provided, the default ChatLLM7 will be used.
• api_key (Optional[str]): The API key for LLM7. If not provided, the package will use the default or the one set in the environment variable LLM7_API_KEY.

Rate Limits

The default rate limits for LLM7's free tier are sufficient for most use cases of this package. If you need higher rate limits, you can pass your own API key via the environment variable LLM7_API_KEY or directly in the function call.

Getting an API Key

You can get a free API key by registering at LLM7.
