I Spoke to My API – Before It Was Even Built

What if you could test your API before writing a single line of backend code? In this talk, I’ll showcase an AI-powered tool I built that lets you upload an OpenAPI spec, automatically validates and enriches it, and — here’s the magic — lets you interact with your API via chat.

Powered by a custom backend and OpenAI agents, this tool enables real-time API simulations: POST, GET, PATCH — all without spinning up a single service. Whether you’re an API product manager or a backend engineer, this talk will show how you can use OpenAPI, AI, and clever tooling to shift API feedback left — radically improving design, testing, and developer experience.

Yogesh will share:

• How the tool validates and fixes your spec
• How you can simulate API workflows with zero backend
• Lessons from integrating OpenAI with a spec-driven execution engine
• Lessons in making OpenAPI ‘executable’ using AI.
