price-tracker-api

Price tracker API for Python — extract any product's price from a live page and log it to CSV. Price-drop monitoring in 3 lines.

price-tracker-api reads a product page through Keiro stealth browsers, pulls the price, and (optionally) appends it to a CSV time series. Point it at a product URL on a cron and you have a price-drop alert bot.

Example output

{"price": 13.76, "currency": "£"}

FAQ

How do I track product prices in Python?

track(url) on a schedule. The CSV it writes is your price history.

Can I get alerts when a price drops?

Read the CSV's last two rows, compare, send yourself a notification. The extraction half is done — alerting is a 3-line if on your side.

Which stores work?

Any page with a visible price — e-commerce product pages are the sweet spot. Heavy anti-bot stores (Amazon-grade) may need a leased stealth browser.

Does it work with JavaScript-heavy store sites?

Yes — pages render in a real stealth browser before parsing, which is the whole point.

Why not CamelCamelCamel / Keepa?

Those are Amazon-only. price-tracker-api tracks any URL you give it — boutique stores, ticket pages, SaaS pricing pages.
