PDF URL Knowledge Base

Learn how to use remote PDFs in your knowledge base.

The PDFUrlKnowledgeBase reads PDFs from urls, converts them into vector embeddings and loads them to a vector database.

Usage

We are using a local PgVector database for this example. Make sure it’s running

pip install pypdf

knowledge_base.py

from agno.knowledge.pdf_url import PDFUrlKnowledgeBase
from agno.vectordb.pgvector import PgVector

knowledge_base = PDFUrlKnowledgeBase(
    urls=["pdf_url"],
    # Table name: ai.pdf_documents
    vector_db=PgVector(
        table_name="pdf_documents",
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
    ),
)

Then use the knowledge_base with an Agent:

agent.py

from agno.agent import Agent
from knowledge_base import knowledge_base

agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)
agent.knowledge.load(recreate=False)

agent.print_response("Ask me about something from the knowledge base")

PDFUrlKnowledgeBase also supports async loading.

pip install qdrant-client

We are using a local Qdrant database for this example. Make sure it’s running

async_knowledge_base.py

import asyncio

from agno.agent import Agent
from agno.knowledge.pdf_url import PDFUrlKnowledgeBase, PDFUrlReader
from agno.vectordb.qdrant import Qdrant

COLLECTION_NAME = "pdf-url-reader"

vector_db = Qdrant(collection=COLLECTION_NAME, url="http://localhost:6333")

# Create a knowledge base with the PDFs from the data/pdfs directory
knowledge_base = PDFUrlKnowledgeBase(
    urls=["https://agno-public.s3.amazonaws.com/recipes/ThaiRecipes.pdf"],
    vector_db=vector_db,
    reader=PDFUrlReader(chunk=True),
)

# Create an agent with the knowledge base
agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)

if __name__ == "__main__":
    # Comment out after first run
    asyncio.run(knowledge_base.aload(recreate=False))

    # Create and use the agent
    asyncio.run(agent.aprint_response("How to make Thai curry?", markdown=True))

Params

Parameter	Type	Default	Description
urls	List[str]	-	URLs for PDF files.
reader	PDFUrlReader	-	A PDFUrlReader that converts the PDFs into Documents for the vector database.

PDFUrlKnowledgeBase is a subclass of the AgentKnowledge class and has access to the same params.
