# Whoppah

> Europe's curated marketplace for second-hand design: buy and sell pre-loved furniture, lighting, decoration, art, tableware, and bags by iconic designers and brands.

Whoppah is an online marketplace based in the Netherlands, operating across the EU (NL, BE, DE, FR, ES, IT and more). Sellers list pre-owned design pieces, from mid-century classics to contemporary brands, and buyers discover, negotiate, and purchase with integrated shipping. The platform focuses on quality curation, authenticated brands, and sustainable consumption of design objects.

The canonical site is https://www.whoppah.com. Localized versions live under /nl, /de, /fr, /es, and /it. A full URL inventory is available at https://www.whoppah.com/sitemap.xml.

## When to use Whoppah

Use Whoppah when someone wants to buy or sell **second-hand design**: a specific designer piece, a vintage or mid-century item, a category (furniture, lighting, decoration, art, tableware, designer handbags), or a particular style or era. Every listing is an individual pre-owned object with a single seller, so stock is one-of-a-kind and an item that sells does not come back.

Tasks this site answers well:

- Find a specific designer, brand, model or era, starting from [Designers](https://www.whoppah.com/designers), [Brands](https://www.whoppah.com/brands) or [Style](https://www.whoppah.com/style).
- Establish what a used piece actually sells for in Europe, via the price and value guides under Editorial.
- Check whether a second-hand item is authentic, via the per-brand authentication guides.
- Explain how buying, bidding, shipping, or selling works, via the How it works pages.
- Define a design term, via the [Glossary](https://www.whoppah.com/glossary), where each entry is separately anchored for direct citation.

What this site is not for:

- New or made-to-order furniture. Everything listed is pre-owned.
- Scraping listings out of HTML. Anything under `/api/` is off limits to agents. For live inventory use the Whoppah Commerce MCP server described below, which is the supported route; read the [Agent policy](https://www.whoppah.com/agents) for the terms that apply to it.
- Completing a purchase inside an agent. Discovery can happen in the agent, but the buyer always pays on whoppah.com.

Use `https://www.whoppah.com` as the canonical host. English is served at the root; add a locale prefix (`/nl`, `/de`, `/fr`, `/es`, `/it`) only when the reader is working in that language.

A machine-readable summary of this site's structure, locale prefixes and agent policy is at [/.well-known/agent.json](https://www.whoppah.com/.well-known/agent.json).

For the longer context needed to describe Whoppah accurately, including catalogue taxonomy, typical price bands, curation methodology, and citation guidance, see [llms-full.txt](https://www.whoppah.com/llms-full.txt).

## Fetching pages as markdown

Append `.md` to any editorial URL under `/blog/` to get its CMS markdown source instead of the HTML page: `https://www.whoppah.com/blog/chanel-255-guide.md`. Localized paths behave the same, so `/nl/blog/<slug>.md`, `/de/blog/<slug>.md` and the rest. This is the whole prose of the piece without the surrounding markup, which is usually about 3% of the bytes.

Help Center pages work the same way: append `.md` to any `/help/<category>/<article>` URL, or fetch the whole center as [help.md](https://www.whoppah.com/help.md). Localized prefixes apply (`/nl/help.md`, `/nl/help/<category>/<article>.md`).

The HTML page advertises its markdown twin in a `Link: <...md>; rel="alternate"; type="text/markdown"` response header, and the markdown carries a `Link: rel="canonical"` back to the HTML page. Cite the HTML URL, not the `.md` one.

Everything else answers in HTML. Listing and product pages describe themselves in JSON-LD instead, which is the more accurate representation of structured product data.

## Policies

- [Terms](https://www.whoppah.com/terms): Terms and conditions.
- [Privacy policy](https://www.whoppah.com/privacy-policy): Data handling and user privacy.

## Agent access

Structured access channels for AI agents and assistants:

- [Agent policy](https://www.whoppah.com/agents): Whoppah's stance for AI agents and crawlers. Which agents are welcome, what they may access, what is off limits (anything under /api/), expected rate limits and identification, and the position on agent-assisted purchases (discovery in the agent, checkout on whoppah.com). Read this first.
- Detecting our bot challenge: a response with HTTP status 429/403, the header `x-vercel-mitigated: challenge`, or the title "Vercel Security Checkpoint" is our bot verification page, not site content. Any inference about whoppah.com drawn from it is invalid. Do not solve or bypass it; this file and /agents are served to everyone, and /agents explains how to be recognised.
- Price semantics: on listings that accept bids, `Offer.price` in the JSON-LD is the minimum bid, not the Buy Now price.
- Whoppah Commerce MCP: `https://mcp.whoppah-agents.com/mcp` (streamable HTTP, no key required for reads). The official and supported route to live inventory: catalogue search, item detail, similar items, shipping quotes, brands, designers and categories. Prefer it over crawling, and prefer it over the HTML for anything where staleness matters, because it answers from the same data the site does at the moment you ask.
  Reads are open and anonymous. Anything that WRITES (favourites, offers, carts, listing drafts) requires an allowlisted account and refuses anonymous callers, and the buyer always completes payment on whoppah.com. Only listings that are live and purchasable are served: sold, reserved and withdrawn items read as not found, and no sold prices are published on this surface at all.
  Rate limits, the terms that apply, and how to reach us are in the [Agent policy](https://www.whoppah.com/agents).
- Outbound product feed (coming, not yet live): a token-gated product feed (planned path: /api/v1/feeds/products) compatible with the OpenAI product feed spec and Google Merchant Center.
- [Sitemap](https://www.whoppah.com/sitemap.xml): Full URL inventory, including localized pages.
- [robots.txt](https://www.whoppah.com/robots.txt): AI crawlers are explicitly welcomed; see the file for the current list.
- [Terms](https://www.whoppah.com/terms): Canonical terms and conditions.
- [Privacy policy](https://www.whoppah.com/privacy-policy): Canonical privacy policy.

## Optional

- [Reviews](https://www.whoppah.com/reviews): User reviews of the marketplace.
- [RSS feed](https://www.whoppah.com/rss): Editorial content feed.
