Problem

Write an API to scrape/fetch Venmo transaction notes with a lot of assumptions & conditions.

Asked in the VO stage. Final VO round coding/design question.

Focus on how you would define the API, access controls, rate limiting, and data handling. Call out what assumptions you need to make about user consent, public vs private notes, and how you would prevent abuse or scraping at scale.
