Repricing eBay listings without the eBay API

Most eBay repricers start by asking for API keys. I wanted one that didn't, so I built HelloDrop that way: the extension works in your own signed-in browser, and the repricer works from the Seller Hub reports you already use.

How it works, briefly: you set the lowest and highest profit you will accept on each listing. The portal counts the listing's orders in the sales bands you define and moves its price one small step at a time on the day you choose — up while it is quiet, down while it sells well, left alone once it is inside your range. It never goes below your minimum, and every change waits for your approval unless you switch auto-publish on yourself.
The same no-API approach runs through the rest of the extension: product scores are computed from the sales and watch data on the page, VeRO Guard checks titles against a 2,482-brand list, and order fulfilment types the buyer's address into the supplier checkout inside the browser — the address never leaves the tab.

It is a free Chrome extension, at hellodroptools.com, working across eight eBay regions. Happy to answer technical questions about the approach.
