Where is the api folder?

Hi,

I’m new to vibe code, its pretty cool. I’m trying to build a tool to scrub some of my emails to create a weekly schedule for my kids. I built most of it using google ai studios. Inside the function where the code scan the email and try to parse for keywords, it calls this ‘/api/ai/scan-emails’. I cant find this file/function/etc anywhere inside my project. What is it? How do tell it what to look for.

Here’s an example of what i’m trying to parse to create a weekly schedule

Monday- Whiteboard practice; Greetings customs in Spanish-speaking countries

Tuesday- Quiz Quiz trade speaking practice; Create a Conversation; Quick Check (Quiz- daily grade)

Wednesday- Ball Toss; Where are you from?; Quiz Quiz trade speaking practice

Thursday- Tic Tac Toe speaking practice; Reading; Interview

Friday- How old are you?; Numbers

The following Monday and Tuesday students will have a speaking assessment (RA).

Thank you
