Inventory monitoring means continuously checking product pages or stock endpoints to detect changes the moment they happen. The hard part isn't reading stock — it's polling thousands of items frequently without getting blocked.
How monitors poll
A monitor repeatedly requests product data and compares it to the last known state, firing an event when something changes.
- Poll product pages or stock APIs on a loop
- Diff against the previous snapshot
- Emit events on availability changes
Staying unblocked at scale
Watching large catalogs means a lot of requests. Rotating residential IPs distribute that traffic so each address stays under the radar.
- Spread requests across many IPs
- Monitor thousands of SKUs in parallel
- Throttle and back off on errors
