API Schema Extractor (http Request)

This workflow automates the process of discovering and extracting APIs from various services, followed by generating custom schemas. It works in three distinct stages: research, extraction, and schema generation, with each stage tracking progress in a Google Sheet.

How this works

This workflow automatically discovers APIs from services, extracts their details, and generates structured schemas, saving teams hours of manual research and documentation. It suits developers and integration specialists who need reliable schemas for connecting tools like Google Sheets or custom applications. The process runs through research, extraction, and schema generation stages, each updating progress in Google Sheets for easy tracking.

Use it when you regularly handle multiple services and need consistent schemas without repetitive effort. Avoid it for one-off tasks or when you need real-time API calls rather than documentation. Variations include adjusting the research depth or focusing extraction on specific endpoints only.
