Bullion Trading: Gold & Silver
Real-time spot, premiums and buy-back rates plus the full bullion catalog of a NYC dealer on 47th Street.
This is the public, read-only Model Context Protocol server of Bullion Trading LLC, a licensed bullion dealer at 20 West 47th Street, New York, since 2008. AI assistants can use it to look up spot prices, product prices and stock, premiums, buy-back rates and store policies.

All 18 tools are read-only. Prices follow spot and are re-quoted at checkout (10-minute lock). Every result links the page it comes from.
get_spot_prices | Current spot prices per troy ounce in USD for gold, silver, platinum and palladium, as used by Bullion Trading LLC: the Ask (what our prices and premiums are measured over) and the Bid (what buy-back rates start from), with the change since the previous 5 pm New York close. |
search_products | Search the Bullion Trading LLC catalog of gold, silver, platinum and palladium coins, bars and rounds. Filter by metal, type, price range and stock; sort by price, popularity or newest. Returns both prices (check/wire and card/PayPal, +5%) and in/out of stock. |
get_product | Full details for one product by id, slug or product URL: both prices, quantity price tiers, in/out of stock, metal, weight, purity, mint, a short description, what we pay to buy it back (if we do) and a price-history link. |
find_bullion | The "Find your bullion" picker: products matching a metal, form, size, purpose or sort order, as on bulliontradingllc.com/find-your-bullion/, with both prices, in/out of stock and the best price per ounce. Sizes look like "1-oz", "1-10-oz", "10-oz", "1-kilo", "1-gram". |
