# StackerScan feature matrix All 38 features of StackerScan at a glance — every way to add, track, price, deal-hunt and share a precious-metals stack. Costs are in credits (10 credits = one receipt scan). Developers and AI agents: the free public API is documented at [/docs](/docs). ## Adding to your stack Every way holdings get into StackerScan — from a photo, a sentence, a spreadsheet, or a form. ### Receipt & document scanning Photograph or upload receipts, invoices and PDFs; StackerScan extracts each item into structured holdings with metal, weight, purity and price. Failed analyses are free, and refunds can be requested on any scan. *requires account · 10 credits per document* ### Coin & slab photo scan Photograph a coin or a graded slab and get it identified, priced and added to your stack. Slab labels are read automatically, including the cert number. *requires account · 1 credit per scan* ### Chat-to-Stack Type what you bought in plain language — "3 silver eagles at 34.50 each" — and StackerScan turns it into holdings. *requires account · 1 credit per saved item* ### Voice input Say what you bought instead of typing it; the same understanding applies. *requires account · 1 credit per saved item* ### Product Find Look up a bullion product or coin by name and get its canonical details prefilled before saving. *requires account · free* ### Spreadsheet import Upload an existing spreadsheet of holdings and map its columns; rows become transactions in bulk. *requires account · 2 credits per row* ### Manual entry A full transaction form for entering any holding by hand, with photos attachable to each item.
