Try the Depop shop API

- This endpoint parses the shop page's rendered HTML, not a JSON API (none was found for per-seller listings) — so each item in `items` is a lighter shape than `/depop/search`'s: no brand, condition, colour, description, or size, since the shop page doesn't render those per card. `id` is the item's URL slug, same identifier space as `/depop/search`'s `id` and `/depop/item/{slug}`'s `slug` — chain any item into `/depop/item/{slug}` for full detail. - `followers_count` and `following_count` are approximate once Depop abbreviates them in the UI (e.g. "2.35K" → `2350`) — Depop doesn't render the exact count past a certain size. - `currency` is always `"USD"` — inferred from the `$` symbol the page renders, not read from an explicit field (unlike `/depop/search` and `/depop/item/{slug}`, which get an explicit currency code from Depop's own JSON). - A shop with no current listings returns `200` with `"items": []`. - If Depop reports current listings but the page's product cards cannot be parsed, the endpoint returns an upstream error instead of an empty listing. - An empty or malformed `username` returns `400` before any upstream request is made. An unrecognized `condition`, `colours`, `sort`, `category`, or `gender` value, a malformed `subcategory` or `sizes` entry, or `price_min` greater than `price_max`, also returns `400`. - A nonexistent username returns `404`.
