LlamaIndex Tools Integration: Exa

This tool connects to Exa, one of the best web search APIs for AI, to easily enable your agent to search and get HTML content from the Internet.

To begin, you need to obtain an API key on the Exa developer dashboard.

Usage

Here's an example usage of the ExaToolSpec.

# %pip install llama-index llama-index-core llama-index-tools-exa

from llama_index.tools.exa import ExaToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

exa_tool = ExaToolSpec(
    api_key=os.environ["EXA_API_KEY"],
)
agent = FunctionAgent(
    tools=exa_tool.to_tool_list(),
    llm=OpenAI(model="gpt-4.1"),
)

print(
    await agent.run(
        "Can you summarize the news published in the last month on superconductors"
