Response fields#

Each item holds count and a data[] array of buckets. Each bucket carries its bucket boundary, price (Steam's median sale price), and volume (number of purchases).

bucket is present on every bucket.
Variant items are not supported.
Valid requested items with no Steam history return not_in_archive; if every valid item has none, the endpoint returns 404 not_found.

Full schemas: ArchiveSteamItem, ArchiveSteamBucket.

Errors#

Status	When
`400 validation_error`	The request body or query failed validation (e.g. bad JSON, missing `items`/`start`, over 100 items, or a bad `interval` or date range).
`401` / `403`	Missing key, invalid key, or plan access.
`404 not_found`	Every valid regular item has no Steam archive rows.
`429`	Rate-limited.
`5xx`	Server-side issue.

When some items resolve and others do not, the request still returns 200 with the resolved items plus an errors[] array. Variant requests use unsupported_variant.
