Full inventory: skins, charms, currencies.

Query

Name	Notes
spaceId	R6 primary space
offset	0 then next page

Cosmetics omit quantity. Currencies have it. Pull Renown / R6 Credits / Level by the known item IDs.

To name items, join itemId against the item catalogue.

App ID

Inventory worker 3587dcbb-…

Host

Redeem an offer into the profile inventory (in-game unlock / grant). offerId comes from the offer catalogue.

Body

type RedeemOfferBody = {
  spaceid: string // note: lowercase "i"
  offerId: string
}

{
  "spaceid": "0d2ae42d-4c27-4cb7-af6c-2099062302bb",
  "offerId": "{offerId}"
}

Only redeem offers the account is entitled to. Failed redeems return 400 / 409 rather than a silent no-op. Response body was not in the dumps.

Response (outer)

type CompressedItemsResponse = {
  compressedItems: string // base64 gzip
}

After decode, each row is a CatalogueItem: itemId, name, tags[], item_type.

zlib.gunzipSync(Buffer.from(res.compressedItems, 'base64'))

Cache this. It is a patch-sized blob, not a per-user blob.

Canonical account level for Siege.

Query

Response

type StatsResponse = {
  profiles: Array<{
    profileId: string
    stats: {
      PClearanceLevel: { value: number }
    }
  }>
}

Read profiles[].stats.PClearanceLevel.value. Prefer this over the inventory Level item or the legacy rewards URL.

Level + XP. Hit/miss — do not use as the canonical level. Use PClearanceLevel.
