Source Rare Items

Rare and niche items rarely appear on mainstream platforms. Vintage electronics, discontinued parts, limited-edition collectibles, and specialty equipment tend to surface on regional classifieds, niche auction sites, or platforms most buyers never check. The challenge is knowing which sources exist for your region and product category, then casting a wide enough net.

By combining `source_coverage` to identify which marketplaces are active in your target region with `search_listings` to sweep all available sources, you can systematically surface inventory that manual browsing would miss. This approach is especially valuable for items where timing matters and listings disappear fast.
