Automated Currency Converter Using Webhook & Google Search

This workflow provides a simple yet powerful automation for currency conversions. It starts with a webhook that captures user queries in a structured format (e.g., '5usd to mxn'). An HTTP Request node then queries Google for the latest exchange rates, extracting precise data from the search results HTML using specialized extraction tools. Finally, it formats the results into a clean, actionable response.

Key benefits include zero reliance on paid APIs, making it cost-effective and scalable for high-volume use. Its simplicity ensures easy integration into larger systems, with robust error handling for input validation and extraction failures. Ideal for dynamic pricing in e-commerce, financial dashboards, or AI agents needing on-demand conversions.

Use cases span professional applications like real-time forex tools, automated invoicing with multi-currency support, and academic projects in data processing. Test via Postman for quick validation, and adapt CSS selectors if Google updates its structure.
