Building No-Code AI Agents with External API Tools: A Practical Guide

Creating AI agents that can access external data sources and perform calculations is becoming increasingly accessible through no-code platforms. This article explores how to build a functional AI agent that can respond to user queries with real-time data and computational capabilities.

Setting Up Your AI Agent Workflow

The workflow for an effective AI agent begins when a chat message is received. This message is processed by the AI agent according to a system prompt, which instructs the agent to answer user questions and format responses in JSON.

To enhance functionality, several tools can be connected to the agent:

  • A chat model connected through open router using a specific language model
  • Memory functionality allowing the agent to remember previous conversations (in this case, up to 5 previous messages)
  • Google Search API for retrieving up-to-date information not contained in the language model’s training data
  • A calculator tool for performing mathematical operations

Testing the AI Agent’s Capabilities

When testing the agent with basic questions, it primarily relies on the chat model and memory functionality without needing to access external tools. However, when asked about current information like the price of Bitcoin, the agent automatically utilizes the Google Search API to retrieve real-time data.

The calculator tool demonstrates its utility when users ask questions requiring mathematical operations. For example, when asked to calculate the difference between Bitcoin’s current price and its value in 2015, the agent seamlessly employs the calculator function to provide accurate results.

Implementing API Connections

The integration with external APIs expands the AI agent’s capabilities significantly. For instance, the Google Search API allows the agent to access current information beyond what’s available in its training data. Documentation is available to understand how each API works within the workflow.

New users can benefit from 1,000 free credits to test the API functionality, and the platform offers a 14-day free trial with 1,000 executions, making it cost-effective to experiment with building comprehensive AI agent workflows.

Conclusion

By combining no-code platforms with external API tools, developers can create sophisticated AI agents capable of handling complex queries requiring both knowledge retrieval and computational abilities. This approach democratizes AI development, allowing more people to build practical applications without extensive coding experience.
