Confirm the ASIN and marketplace pairing: query the product endpoint with the same ASIN and the domain code the watcher uses.

Check the product record tracking and availability fields to see when Keepa started tracking it.

Request a short recent stats window first instead of the full history.

Verify the request asks for history data and not only current stats; an omitted history flag returns metadata with empty series.

If the series is still empty and tracking is recent, mark the ASIN as warming up in the watcher and schedule a recheck in 24 hours instead of alerting on missing data.

Re-run the price poll for the ASIN and confirm the alert logic fires only on a genuine drop between two real points.
