API Documentation

Unified price for an item across all 11 tracked marketplaces. All money values are integer MINOR units (cents): 2813 means 28.13. Every response carries a `unit` field so you never have to guess.

Price up to 20 items across all markets in one call.

}

Current price for an item (cached Steam Market, live fallback). NOTE: `price` is a MAJOR-unit decimal (42.16) - the only endpoint that is; every other price endpoint returns integer cents. Each response carries a `unit` field.

Daily price history (cross-source average + volume). Returns up to 365 days.

Deal finder: items priced below Steam across markets.

Bulk market feed: floor, cross-market spread, top buy order, supply and 7d change for the whole catalogue in one call. Page size scales with your plan (free 100 > enterprise 10,000).

Biggest gainers and losers over a window, from daily price history. Penny items and newly-tracked items are filtered out so the list is real movement, not noise.

Aggregate market index (rebased to 1000 at first snapshot) with history and a per-marketplace breakdown. itemCount is returned per point so coverage changes can be told apart from real moves.

Fee-aware arbitrage: buy the cheapest listing, sell where the net return after commission is highest. Returns buyFrom/sellTo, netProfit, roi and a confidence flag. Unlike /deals, the numbers are after fees.

Exact float, paint seed, pattern (Doppler phase, blue-gem tier, Fire&Ice), stickers with images and sticker value (USD), and item name+image.

Price a specific item instance: the float picks the wear bucket, the paint seed surfaces pattern premiums (Doppler phase, blue gem, Fire & Ice). Returns the full wear price curve, and real per-phase Doppler prices where available.

Live Steam order-book depth for a CS2 item: bid/ask ladder, spread, total buy/sell interest, plus the Buff buy-order as a cross-venue instant-sell reference. No other public CS2 API exposes this.

Lowest (or highest) float leaderboard for a skin.

Public inventory priced per item with total value, plus a summary (rarity breakdown, tradable/marketable counts, top items). Supports any game.

Up to 10 inventories in a single request.

Daily value-over-time history for a tracked inventory.

Steam profile with level, CS2 playtime (hours), VAC/trade/community ban status, avatar and country.

Friend list with friendship timestamps.

Full paginated item catalog (up to 500/page). CS2 returns all ~15K wear-specific items from the asset DB with image, type and rarity. Other games return names seen in the prices collection. Add ?prices=true to include the lowest known price per item.

Autocomplete over the CS2 skin schema. Returns BASE names (no wear suffix) - good for a picker; use /search if you need a name you can price directly.

Search the tracked item database (any game) and get exact market_hash_names WITH the wear suffix, plus image and rarity. These are the names /markets, /items and /history expect - start here when a price lookup returns missing_wear.

Full metadata for an item (weapon, rarity, collection, crates, float range).

CS2 cases, capsules and collections: every set with its full item pool, the rare knife/glove pool, release date and live container price.

Live USD-based FX rates - the same table every price endpoint uses for ?currency=. Pass from/to/amount to convert a single value.

Resolve a SteamID64, vanity name or pasted profile URL to every ID format (SteamID64, STEAM_1:Y:Z, [U:1:id], account id).

Trade-up calculator: 10 items of the same rarity + collection -> possible outcomes, probabilities, EV.

List every price alert on your account. Each fires when an item's lowest price crosses your threshold, via webhook, Discord and/or email.

Create a price alert. threshold is in your currency (e.g. 40 with currency=EUR) and fires when the item's lowest price goes below (or above) it. Provide at least one channel.

{
  "name": "AK-47 | Redline (Field-Tested)",
  "game": "cs2",
  "threshold": 40,
  "currency": "USD",
  "direction": "below",
  "discordUrl": "https://discord.com/api/webhooks/…",
  "email": "[email protected]"
}

Fetch a single alert by id.

Update an alert. Only the fields you send change; pass a channel as "" to clear it, active=false to pause.

{
  "threshold": 35,
  "direction": "below",
  "active": true
}

Delete an alert.

Find profitable trade-up contracts ranked by return on cost after fees. Scans single-collection contracts (10x the same skin) across every collection, rarity and wear. Verify a candidate with POST /v1/tradeup before crafting - input floats here are assumed.

Case/capsule opening expected value: per-rarity odds and average values, the knife/glove pool, EV after sell fees, break-even case price and the chance of profiting. Unboxing is gambling - for almost every case the EV is below the key price.

Public component health: DB connectivity, price ingest freshness, Buff source status, market source reachability. No auth required.

Minimal liveness probe: { status, db, time }. No API key required - intended for uptime monitors and load-balancer checks. Use /status for per-component detail.
