Free text: a model name, a brand, a serial-era nickname, anything a buyer would type. Optional — leave it out and send a filter instead to browse a whole category or shop.

Brand name(s), exactly as Reverb spells them (Fender, Gibson, Squier, Boss, Roland). Several values are OR-ed: ['Fender','Gibson'] returned 117 853 guitars against 790 216 unfiltered. 🔴 Reverb matches brand FAMILIES: asking for Squier also returns rows whose own `make` field reads 'Fender' (5 of 24 on a measured page — 'Fender Squier Sonic Stratocaster'). Filter on the row's `make` yourself if you need the strict brand.

Top-level department. Only ONE value is accepted — an array here is a 400 from the source. Use `category_uuid` for a sub-category such as Solid Body.

A sub-category uuid from `categories` — e.g. Electric Guitars / Solid Body narrowed the marketplace to 148 331 listings. 🔴 The category SLUG on its own is silently ignored by the source, which is why this API takes the uuid.

Condition grade(s). Several values are OR-ed. 🔴 The source silently ignores a slug it does not know, so this API validates it — and note that Brand New is `new`, not `brand-new`.

Lowest price in US dollars, inclusive. (0–)

Highest price in US dollars, inclusive. With price_min=1000 this narrowed 'stratocaster' from 76 993 to 8 390. (0–)

Earliest build year the seller stated. 🔴 Only ~49 % of listings state a year, so a year filter also drops every listing with no year. (1800–2100)

Latest build year. 1960-1969 left 770 stratocasters of 76 993. (1800–2100)

Where the ITEM is, as a two-letter country code (US, GB, DE, JP). US 56 778 vs GB 5 051 on the same search.

Only listings that ship to this two-letter country code. 🔴 Leave it out and the source answers for 'Everywhere Else', which is NOT the whole marketplace — pinning ships_to=US cut 'stratocaster' from 77 000 to 41 496. The value actually used is echoed in `ships_to` on every response.

Only this shop's listings. The NUMERIC id — a shop slug here is silently ignored by the source and hands you the whole marketplace, so use `shop/listings` if you only have a slug.

Only items the seller marked handmade (2 817 of 76 993).

Only items that ship free to somewhere (416 of 76 993). 🔴 This is NOT the row's `free_expedited_shipping` flag, which was False on all 8 rows a measured call returned — read `has_free_shipping` and `shipping_rates` to see which region the 0.00 rate is for.

Only items offering local pickup (26 252 of 76 993).

Only Reverb Preferred Sellers (48 914 of 76 993).

Leave empty for Reverb's own relevance order. Only the three orders the source demonstrably applies are offered; it silently ignores any other value. 🔴 The price sort is monotonic in the SELLER's currency, not in the USD you are handed: on a measured `price_desc` page a JPY listing converting to $98,652 came ahead of a USD one at $100,000. Sort by `price_usd` yourself if you need exact USD order.

1-based page number. The source prints `total_pages: 50` on every envelope no matter how large the result is — that cap is cosmetic and this API ignores it: pages 51, 60, 100 and 200 all return real, distinct rows. Read `total_pages` from this response, which is computed from `total`. (1–)

Rows per page, 1-50. 50 is the source's own ceiling; it clamps anything larger instead of refusing it, so this API clamps it too and tells you in `limit`. (1–50)
