Header Parameters

Idempotency-Key?string

Optional. Send a unique key per logical operation to make retries safe: a retry with the same key replays the stored success for 14 days instead of re-running the write. Reusing a key with a different body returns 400.

Summarize inventory GET

Server-computed aggregates over the gallery's artworks for a filter set: the matching total, counts by work status, value totals summed per currency, and the unpriced count. Accepts the same filters as the list endpoint (status, artist_id, price/year bands, unpriced, published). Use this — not paging the list — to answer 'how many' / 'how much' questions correctly at any scale.

Remove a tag from a artwork DELETE

Removes a single tag from this artwork (idempotent). Returns the resulting tag set.
