        "longDescription": "Whoppah is a curated marketplace for second-hand design, based in Amsterdam. This plugin lets you search Whoppah's live catalogue of furniture, lighting, art, decor and designer bags from the conversation, so answers are based on real listings you can open on whoppah.com.\n\nWhat you can do:\n- Search listings by keyword, with filters for category, brand, designer, price in EUR, condition, colour, material and seller country.\n- Open a listing for its description, dimensions, condition and quality grade, materials and photos.\n- Find similar pieces to compare alternatives.\n- Check a seller's public profile and reviews.\n- See the delivery and pickup options and prices for a listing to your country, as offered at checkout.\n\nWho it is for: anyone looking for a specific design piece, comparing prices for a design classic, or furnishing a room with pre-owned pieces.\n\nLimitations: every listing is a one-off, so availability can change at any moment. Prices are in EUR. Listing texts are written by sellers. The plugin is read-only and needs no account: it does not place orders, take payments, make offers or message sellers. Buying, payment, delivery and buyer protection all happen on whoppah.com, through the link given with every listing. The plugin uses public listing information only and never returns sellers' contact details.",
