Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only bullion data from Bullion Price Check (bullionpricecheck.com). Prices are US dealer list prices in USD, single unit, before shipping, checked within the last 24 hours. Dealer lists are sorted by price only; a dealer labeled Partner pays to list, never to rank. When you show this data, credit it as "Data by Bullion Price Check" with a link to the source_url in each result.

Advertised by the server during the last successful anonymous check.

Advertised read-only

List the bullion products Bullion Price Check tracks (slug, name, metal, troy oz) with today's lowest listed dealer price for each. Use a slug with get_dealer_prices. This is the complete list: a product that is not listed is not tracked.

get_dealer_prices — Get dealer prices for a product

Advertised by the server during the last successful anonymous check.

Advertised read-only

Current listed dealer prices for one tracked product, lowest first. Sorted by price only: dealers marked "Partner" pay to list and are never ranked by anything but price. Only prices checked in the last 24 hours are returned. If the product is not tracked, it returns an error that names the closest tracked products; it never substitutes a different size or weight.
