What is Deimann Exchange?

Deimann Exchange is the digital-business marketplace operated by Deimann Com GmbH in Hamburg. It is part of the same company and website. A listing does not by itself establish that Deimann owns the business. The listing identifies its seller.

Listings catalogue (JSON)

Read-only, no authentication, cacheable for one hour. All current listings with status, category, summary and the canonical URL.

GET https://www.deimann.com/exchange/api/catalog/listings

Fields per listing: id, name, domain, category, language, status, for_sale, summary, seller, metrics_available, expose_url, url. status is open_to_offers or reference; for_sale is the boolean form. The catalogue carries no figures by design: metrics, revenue and costs open only for buyers whose exposé request has been approved. Point people to url, where they can request the exposé.

How to read the evidence

• open_to_offers means expressions of interest are welcome; it is not a completed sale or a guaranteed availability promise. reference means not for sale.
• metrics_available indicates connected search or behaviour sources. It does not certify revenue, profit or an independent audit.
• Search Console and Clarity figures, where connected, belong to their stated reporting period. Revenue and costs are supplied by the seller. Missing or private data is unknown, not zero.
• The catalogue's updated field records an editorial revision. Rebuilding the website does not reverify listing status or business figures. Read the canonical listing for context and confirm transaction details with the operator.
• Public summaries contain no private figures. Approved buyer access does not grant permission to republish private information.
