answer imperative

Find canonical bullion products (coins, rounds, bars) in the Coindex catalog by name, alias, metal or weight, e.g. "silver eagle", "1/10 oz gold eagle", "maple leaf", "10 oz silver bar". Returns canonical ids to pass to get_bullion_ask_reference or calculate_melt_value, and the Coindex page URL where one is published. Identity only: no prices.
