Team Fortress 2 inventory

TF2 inventory API with item values

Check a TF2 backpack before you integrate

Team Fortress 2 uses Steam AppID 440, context 2. Select TF2 in the read-only inventory checker for a manual preview, or use game=tf2 with the authenticated API below.

Run the TF2 curl, Node.js or Python request with a public SteamID64. Set top=0 when you need every grouped item row. Steam may still return private or empty; read status before using items.

Display items_total and unpriced beside total. WOK's auto mode prefers a matched backpack.tf quote, then other accepted saved sources; items[].pricesource tells you which observation actually priced each item.

Check items[].priceupdatedat separately from meta.cache_age. Grouped market names and matched prices provide a baseline, while unusual effects and instance attributes can change an individual item's value. For repeated roster reads, use batch requests; quota is per player-game pair.

Response schema

Stable fields for typed clients, storage and error handling.

TF2 inventory API with item values response schema
Field	Type	Meaning
`steamid`	`string`	Canonical 17-digit SteamID64.
`game`	`string`	Documented key: cs2, rust, tf2, dota2, pubg, sandbox, unturned or payday2. Numeric Steam appids are also accepted and returned as app<appid> without catalog pricing.
`status`	`string`	ok, empty, private, notfound, limited or error.
`total`	`number`	Priced sellable inventory total in USD.
`items_total`	`integer`	Number of item instances before top truncation.
`sellable`	`integer`	Tradable and marketable item instances, including unpriced ones; total sums matched values.
`untradable`	`integer`	Item instances excluded from sellable value.
`untradable_value`	`number`	Value of excluded untradable items in USD.
`tradelocked`	`integer`	Item instances currently trade locked.
`tradelocked_value`	`number`	Value of trade-locked items in USD.
`unpriced`	`integer`	Instances without a usable price.
`items[]`	`array`	Items with market names, count, trade state, prices and optional inspect links.
`items[].markethashname`	`string`	Canonical price-catalog market hash name.
`items[].marketname`	`string`	Steam market display name when supplied.
`items[].type`	`string`	Steam-supplied item type text; not a WOK-normalized category.
`items[].count`	`integer`	Grouped item instance count.
`items[].tradable`	`integer`	Steam tradability flag, 0 or 1.
`items[].marketable`	`integer`	Steam marketability flag, 0 or 1.
`items[].tradelocked`	`boolean`	Whether the grouped item is trade locked.
`items[].tradelockuntil`	`number\|null`	Unix expiry when a trade lock is known.
`items[].pricemedian`	`number\|null`	Selected source median price in USD.
`items[].pricesource`	`string`	Selected catalog source; empty when the item is unpriced.
`items[].priceupdatedat`	`number\|null`	Selected source observation time, separate from inventory cache age.
`items[].prices`	`object`	Per-source USD prices.
`items[].inspect_links`	`array`	Optional CS2 inspect actions.
`meta`	`object`	Cache age/TTL, cached/shared flags, timing, bytes, lane and upstream-attempt metadata.

`meta.cache_age`	`integer`	Snapshot age in seconds.
`meta.cache_ttl`	`integer`	Applied freshness window in seconds.

Limits and error behavior

Rules clients should handle explicitly in production.

The Steam inventory must be public. Private, missing and empty inventories are distinct statuses, not successful empty data.

top accepts 0 through 100. top=0 returns every item row; items_total still describes the complete inventory when a top limit is used.

Prices are USD. An item can be valid while pricemedian is null; use unpriced instead of treating missing prices as zero-value evidence.

A partial or malformed Steam inventory is not saved as a successful snapshot. On GET /v1/inventory, validation/auth failures use HTTP 400/401/402/404/422/429; Steam outcomes private, notfound, limited and error are returned with HTTP 200 in response.status. The compatibility GET /steam/api/inventory maps them to 403/404/429/502 (empty to 410).

Unusual effects and item attributes can make a specific TF2 instance worth more than its market hash name estimate.

Cache and freshness semantics

How to tell whether data was reused, shared or refreshed.

Successful inventory snapshots use a 1,800-second default TTL. Negative defaults are 21,600 seconds for empty, 3,600 seconds for private and 600 seconds for not found.

For authenticated inventory responses that reach validation/result handling, read X-Wok-Cache-Age and X-Wok-Cache-TTL when present; authentication and quota errors may omit them.

Identical concurrent misses are coalesced. A waiter receives X-Wok-Singleflight: 1 and does not start another Steam inventory fetch.

Use refresh_prices=1 or POST /v1/inventory/refresh-prices only with an active compatible OK/EMPTY snapshot. Repricing never fetches Steam or resets inventory age/TTL; 404 inventory_cache_miss means run a normal inventory scan. refresh_prices=1 cannot be combined with no_cache=1; prices_updated_at identifies the repricing operation.

Frequently asked questions

Direct answers about access, freshness and result semantics.

Which game value selects Team Fortress 2?

Use game=tf2 with GET /v1/inventory.

How do I read every grouped TF2 backpack item?

Use top=0, then check status before using items or total. A private backpack is not an empty one. Inspect unpriced and each item's pricesource and priceupdatedat before displaying a complete value.

Are unusual TF2 items valued exactly?

A grouped market-name price is an estimate. Effects and instance attributes can require a separate appraisal.
