Common Patterns

Display Currency with Cap

local function ShowCurrency(currencyID)
    local info = C_CurrencyInfo.GetCurrencyInfo(currencyID)
    if info then
        local text = info.name .. ": " .. info.quantity
        if info.maxQuantity > 0 then
            text = text .. " / " .. info.maxQuantity
        end
        if info.canEarnPerWeek and info.maxWeeklyQuantity > 0 then
            text = text .. " (Weekly: " .. info.quantityEarnedThisWeek .. "/" .. info.maxWeeklyQuantity .. ")"
        end
        print(text)
    end
end

Auction House Search

-- Register for results
local f = CreateFrame("Frame")
f:RegisterEvent("ITEM_SEARCH_RESULTS_UPDATED")
f:SetScript("OnEvent", function(self, event, itemKey, ...)
    local numResults = C_AuctionHouse.GetNumItemSearchResults(itemKey)
    for i = 1, numResults do
        local result = C_AuctionHouse.GetItemSearchResultInfo(itemKey, i)
        if result then
            print(result.buyoutAmount, "copper -", result.quantity, "available")
        end
    end
end)

-- Initiate search
local itemKey = C_AuctionHouse.MakeItemKey(12345) -- itemID
C_AuctionHouse.SendSearchQuery(itemKey, {}, false)

Check WoW Token Price

C_WowTokenPublic.UpdateMarketPrice()

local f = CreateFrame("Frame")
f:RegisterEvent("TOKEN_MARKET_PRICE_UPDATED")
f:SetScript("OnEvent", function()
    local price = C_WowTokenPublic.GetCurrentMarketPrice()
    if price then
        print("WoW Token: " .. GetCoinTextureString(price))
    end
end)

Key Events

Gotchas & Restrictions

1. Auction House hardware event — Posting, buying, and bidding require hardware events (user clicks).
2. Commodity vs. item — Commodities (stackable) use a different API path than equipment/unique items.
3. AH throttling — Searches are rate-limited. Rapid queries get throttled by the server.
4. Mail COD — COD mail auto-deducts gold when attachment is taken. Test with InboxItemCanDelete().
5. GetMoney() returns copper — Divide by 100 for silver, 10000 for gold.
6. Currency caps — Always check maxQuantity and maxWeeklyQuantity before displaying progress.
7. WoW Token price is async — Call UpdateMarketPrice() then wait for TOKEN_MARKET_PRICE_UPDATED.
8. ReplicateItems() is slow — Full AH scan is expensive. Use sparingly and handle results incrementally.
