When you use the Bigdata.com Chat API, every answer can be traced back to its sources. This is called inline attribution. Inline attribution helps you understand where the information comes from, providing transparency and trust in the responses. This guide will show you how to: ✅ Install bigdata-client package
✅ Read inline attribution details
✅ Retrieve the full document
✅ Get the favicon
You can display those details in your proprietary Chatbot in the same way as Bigdata App: Chat source details Ready to get started? Let’s dive in!
The steps below provide code snippet examples, please refer to the section Complete script to see the complete script.

​
Install bigdata-client package

Follow Prerequisites instructions to set up the require environment.

​
Read inline attribution details

The following script will create a chat, ask a question and print the inline attribution details from the response sources.
  • headline: The title of the document.
  • id: A unique identifier for the document in Bigdata.com.
  • URL: The direct link to the source document (if available).
  • timestamp: The publication date/time of the document.
  • image_urls: A representative image from the document (if available).
from bigdata_client import Bigdata

bigdata = Bigdata()

# Create a new chat and ask a question
chat = bigdata.chat.new("Quantum Computing")
response = chat.ask(
    "What companies are researching on Quantum Computing?",
    streaming=True,
    scope=ChatScope.NEWS
)

print(f"\nDocuments used to craft the Chat response:\n")
for source in response.sources:
    print(f"\tHeadline: {source.headline}")
    print(f"\tDocument ID: {source.id}")
    print(f"\tURL: {source.url}")
    print(f"\tTimestamp: {source.timestamp}")
    print(f"\tImage URL: {source.image_urls[0] if source.image_urls else 'N/A'}")

​
Retrieve the full Document

If the document is an indexed Bigdata.com document, you can download the full annotated document with the following script. 
    # Retrieve the full document using the Document ID
    doc_id = source.id
    documents = bigdata.search.new(query= Document(doc_id)).run(1)

    if documents:
        doc = documents[0]
    else:
        raise ValueError("Document not found")

​
Getting the Favicon

We need the ID of the indexed source that published the document, and use the Knowledge Graph’s get_sources method. 
    # Get the source metadata with the favicon URL
    sources = bigdata.knowledge_graph.get_sources([doc.source.key])
    print(f"\tFavicon URL: {sources[0].favicon}")

​
Complete script

This script creates a Chat, asks a question, prints the question and the answer, and prints inline attribution details for each document used to craft the Chat response. Then it also downloads the entire annotated document and saves it in your directory.

    print(f"\tThumbnail image URL: {source.image_urls[0] if source.image_urls else 'N/A'}")

    print(f"\tFavicon URL: {sources[0].favicon}")

    with open(f'annotated_doc_{doc_id}.json', 'w', encoding='utf-8') as outfile:
