Integrating External APIs as Tools
Connect your RAG system to external APIs and services, allowing agents to fetch real-time data or perform actions.
Agents & External APIs
Agents can do more than just generate text! They can interact with the real world by using special functions called "tools." External APIs are perfect for this, allowing agents to fetch real-time data or perform actions.
Tools for Real-World Interaction
In LangChain, a tool is essentially a Python function that an agent can call. These functions can wrap almost anything:
- Searching the web
- Querying a database
- Sending emails
- Interacting with an external API
Tools give agents superpowers, extending their capabilities beyond their internal knowledge.
