The Wikipedia Reader allows you to search and read Wikipedia articles synchronously, converting them into vector embeddings for your knowledge base.

Code

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.wikipedia_reader import WikipediaReader
from agno.vectordb.pgvector import PgVector

# Create Knowledge Instance
knowledge = Knowledge(
    name="Wikipedia Knowledge Base",
    description="Knowledge base from Wikipedia articles",
    vector_db=PgVector(
        table_name="wikipedia_vectors", 
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai"
    ),
)

# Add topics from Wikipedia synchronously
knowledge.add_content(
    metadata={"source": "wikipedia", "type": "encyclopedia"},
    topics=["Manchester United", "Artificial Intelligence"],
    reader=WikipediaReader(),
)

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

# Query the knowledge base
agent.print_response(
    "What can you tell me about Manchester United?",
    markdown=True
)
