SteamWebAPI to WOK API

Migrate from SteamWebAPI to WOK

Start with compatible endpoint paths. Validate prices, grouping, errors and quotas before switching your customers.

Configuration changeBASE_URL + API_KEY

- BASE_URL = "https://www.steamwebapi.com"
+ BASE_URL = "https://woksteamapi.com"

- API_KEY  = "your-steamwebapi-key"
+ API_KEY  = "your-wok-key"

The legacy ?key= parameter works. Prefer a server-side Bearer header so the key stays out of URL logs.

Map the endpoints you use

WOK supports the inventory and profile paths below, not every SteamWebAPI feature or parameter. Native endpoints have different contracts.

SteamWebAPI to WOK API endpoint mapping
Current call	WOK API	Notes
`/steam/api/inventory`	`GET /steam/api/inventory`	Success is an item array. Grouped by default; validate missing prices, item fields and HTTP errors.
`/steam/api/profile`	`GET /steam/api/profile`	One profile object. Check the documented fields rather than assuming full field parity.
Inventory totals and metadata	`GET /v1/inventory`	Native object with `status`, `total`, `items` and `meta`. Not an array replacement.
Multiple inventories	`POST /v1/inventories`	Native `results[]` envelope with per-pair success and errors. Adapt the payload and parser.
Price lookups	`POST /v1/prices`	Look up market hash names without scanning Steam; use the price API guide.

Reference: WOK OpenAPI. FACEIT has its own documented WOK endpoints; it is not a claim of SteamWebAPI endpoint compatibility.

Run a compatibility request

Set WOK_API_KEY in your server environment. Use a public SteamID64; the Python example requires the requests package.

curlinventory

curl --fail-with-body --max-time 35 -G "https://woksteamapi.com/steam/api/inventory" \
  -H "Authorization: Bearer $WOK_API_KEY" \
  --data-urlencode "steam_id=76561198090744629" \
  --data-urlencode "game=cs2" \
  --data-urlencode "currency=USD" \
  --data-urlencode "price_source=auto" \
  --data-urlencode "group=1"

response = requests.get(
    "https://woksteamapi.com/steam/api/inventory",
    headers={"Authorization": f"Bearer {os.environ['WOK_API_KEY']}"},

response.raise_for_status()  # Handle 403/410/429/5xx in your application.
items = response.json()
if not isinstance(items, list):
    raise ValueError("Expected the WOK compatibility inventory array")

print("Sellable value (USD):", response.headers.get("X-Wok-Total"))
for item in items:
    # Missing prices are unknown values, not proof that an item is worthless.
    print(item["markethashname"], item["count"],
          item["pricemedian"], item["pricesource"])

Test before signup

The public demo allows 2 lookups per day per IP.

GET /public/demo?steam_id=76561198090744629&game=cs2

Choose a price source when needed

Pass price_source explicitly when comparing valuations. An omitted value uses the key or server default; auto explicitly chooses automatic selection.

autosteamsteam_buyskinportmarketbackpacktfbuffmix

?price_source=steam_buy&strict=1

auto uses an ordered preference, not the highest available price, and excludes BUFF163. mix selects the lowest eligible market price and can include a BUFF163 observation no older than 72 hours after an outlier check. Steam buy orders are excluded from both. Choose buff&strict=1 for BUFF-only values or steam_buy explicitly for a buy-order value.

strict=1 prevents fallback outside the selected mode; steam remains a family of Steam observations, not one feed. With a missing strict-source price, pricemedian can be null. Inspect pricesource, priceupdatedat and prices rather than assuming every item has that source.

Values are USD, not cents. The legacy currency parameter does not convert WOK responses. BUFF163 pricing covers supported CS2 catalog items; it does not provide BUFF account trading or order execution.

Check the contract before cutover

Replay a small set of saved responses in staging, then compare bounded live requests for the same SteamID, game and source.

What to validate when migrating from SteamWebAPI
Check	WOK behavior and acceptance check
Items and units	`group=1` groups equivalent rows with `count`; `group=0` exposes individual `assetid` strings. Check quantities, tradability and null prices. Use `X-Wok-Total` for the compatibility sellable total in USD, not a sum of every row.
HTTP errors	Compatibility inventory: 403 private, 404 not found, 410 empty, 429 rate or capacity limit, 502 upstream failure. Handle authentication, quota and validation errors separately. Do not turn a failed scan into a zero-value inventory.
Native responses	A native inventory can return HTTP 200 with `status=private`, `notfound`, `limited` or `error`. For batches, inspect every `results[].ok` and `results[].error`; HTTP 200 does not mean all pairs succeeded.
Freshness	`X-Wok-Cache-Age` and `X-Wok-Cache-TTL` describe the inventory snapshot. Each item's `priceupdatedat` describes its selected catalog source. A cache hit can contain repriced items without a new Steam scan.
Repricing and retries	`refresh_prices=1` reprices an active snapshot locally; a missing snapshot returns 404 `INVENTORY_CACHE_MISS`. Do not combine it with `no_cache=1`. Use bounded retries with backoff, and `Retry-After` when supplied.

For native inventory batches, reserve one quota unit per player-game pair, with at most 80 pairs per call. A 20-player workload across eight games needs 160 units and at least two batches. GET /v1/key reports your effective remaining quotas without consuming a unit.

Route a small share of traffic only after these checks pass. Keep your previous configuration for rollback, and compare error rate, missing prices, inventory age and latency under the same workload. WOK is independent of SteamWebAPI; this guide does not promise complete feature parity.
