Alert on opportunity matches

The problem

A keyword match is not an opportunity.

Illustrative day · one search

Keyword matches 142
Manual checks remaining 38
Low asking-price flags 4

False positives in every saved search.

An asking price alone does not prove resale margin.

Strong listings can sell before you finish the manual checks.

Product direction preview

The current beta uses search matching and recent active asking-price patterns. Sold-price evidence, resale ranges, and condition and risk signals are being built next.

Concept preview — not a current beta alert. Values are illustrative estimates, not a guaranteed resale outcome.

Questions

Quick answers.

How is this different from eBay saved search alerts?

The current beta filters listings using your search rules and highlights asking prices that look low against recent matched listings. You still verify sold comps, condition, shipping, fees, and true resale margin before acting.
