Monitor competitor marketplace prices

The poster uses Grok Bot to check competitor listings and product prices over time, though CAPTCHAs block it on some sites.

What They Did

The poster says they use Grok Bot to periodically check product prices and competitor listings on a few online marketplaces. The bot browses those sites on its own, but some marketplaces interrupt it with CAPTCHAs; the poster says they currently have to use an API to solve them, and commenters suggested lower request rates, logged-in sessions, or routing the bot’s traffic through the user’s own device.

How It Went

It works for ongoing marketplace price checks, but reliability breaks on sites that throw CAPTCHAs, including a mouse-movement puzzle. No performance numbers or savings are given.

Worth Knowing

The main catch is that CAPTCHA handling was not solved natively in the thread; the poster says they are using an API for it.
