Monitor Regional Resale Inventory
Track used inventory across marketplaces and regions without manually rerunning the same search on every site.
Build Sourcing Watchlist
Set up ongoing procurement monitoring by mapping source coverage, searching listings, and saving compact watchlist snapshots.
ToolProcurement teams and resellers need more than one-off searches. They need a repeatable process that maps which marketplaces cover their target regions, runs structured searches across those sources, and saves compact snapshots they can compare over time. Without this, sourcing stays reactive: you search when you remember, miss windows when inventory appears and disappears, and lose track of which sources you already checked.
By combining `source_coverage` to map the landscape, `search_listings` to sweep active sources, and `watchlist_snapshot` to save the result, you build a monitoring pipeline that turns ad-hoc browsing into systematic sourcing. Each snapshot becomes a data point you can diff against future runs to spot new inventory, price changes, and source shifts.

- Describe the procurement scope: items, regions, conditions, budget, and who will use the watchlist.
- Run `source_coverage`, `search_listings`, and `watchlist_snapshot` through `marketplace-search` to build the initial watchlist.
Copilot
