Immobilien Scout GmbH, Invalidenstrasse 65, 10557 Berlin
(hereinafter referred to as ImmoScout24).

The user of the ImmoScout24 Application Programming Interface shall hereinafter be referred to as Licensee.
Status of the Terms of Use: 15.08.2022
These API-Terms of Use stipulate the permitted options of using data through a certain Application Programming Interface (hereinafter referred to as “API”) by the Licensee of ImmoScout24. To the extent the Licensee is not certain in concrete use cases, it shall be obliged to obtain a permit from ImmoScout24. The List of Definitions in the Annex is applicable to these API-Terms of Use.

1. Scope of Application

  1. Under these API-Terms of Use, ImmoScout24 provides to the Licensee a non-exclusive license for the use of data from the ImmoScout24 database via an Application Programming Interface, the API, specified by ImmoScout24. These Terms of Use shall also apply to all further API webservices of ImmoScout24.
  2. By using the API of ImmoScout24, the Licensee consents to these API-Terms of Use.
  3. The API-Terms of Use shall also apply if it is not expressly pointed out that such terms apply to the use of further API sites and services of ImmoScout24 as well as to further and new potential uses in the API after the first use and/or registration.

2. Licence Terms

  1. The use of the API shall be subject to the conclusion of a Use Contract. Such contract shall be established by the Licensee registering as user (offer) and ImmoScout24 granting access to the registered area (acceptance of the offer). ImmoScout24 shall be free to decide whether or not it will accept the offer and may decline at any time a registration without the obligation to provide reasons.
  2. The Licensee is only granted the rights of use explicitly stated in these API-Terms of Use. Any industrial property rights and copyrights to the ImmoScout24 Data and to the ImmoScout24 Brand (ref. Article 8) shall not be transferred.
  3. The Licensee shall treat the access data in a confidential manner. It shall be prohibited from disclosing such access data to third parties or from providing such third parties with access to such access data.
  4. Regarding data which the Licensee may provide to End Customers via the software of the Licensee pursuant to the provisions of the Use Contract, the Licensee is obliged to clearly identify them as data of ImmoScout24. For this purpose, it shall identify ImmoScout24 as the data source.

3. Prices

  1. The Licensee is obliged to pay a fee for certain API usages as defined by ImmoScout24 (hereinafter referred to as “Pay Use”). For any Pay Use the Licensee has to secure a respective booking with ImmoScout24; the conditions (incl. prices) for the Pay Use will be provided in course of the booking.
  2. The "Real Estate Listing API", which is subject to payment and can be used for the publication and management of properties on the ImmoScout24 portal, is exempt from the need for a booking pursuant to para. 1. By using the "Real Estate Listing API", the Licensee(s) agrees to the obligation to pay remuneration even without separate booking. The monthly remuneration is calculated in each case from the monthly average of the API calls of the three (3) previous months on the basis of the volume-based Real Estate Listing API price list, which is available HERE. A review of the aforementioned usage volume and a therefore possibly required remuneration adjustment based on the API price list shall be carried out automatically every three (3) months.
  3. ImmoScout24 is entitled to adjust prices and price lists once per calendar year with effect for the licensees. ImmoScout24 shall inform the licensees subject to remuneration about the adjustment by means of the API newsletter in due time before the price adjustment becomes effective. Should the prices increase by more than 15%, the licensees subject to remuneration shall have the right to object to this in writing.
  4. The prices are subject to Value Added Tax (VAT). Invoices shall be issued monthly in advance, unless otherwise agreed between the contracting parties. The fee is due with invoice receipt.
  5. ImmoScout24 and the Licensee may agree on deviating terms in the bookings, cooperation agreements or other agreements in writing. Such terms would prevail these Terms of Use.

4. Registration and Access

  1. For API registration, the Licensee shall follow the procedures set forth in the registration section. Upon API registration, the Licensee subscribes to the API newsletter which contains especially technical information on the use of the API. The Licensee consents to accepts the newsletter as unilateral means of communication of ImmoScout24 regarding the API and the Use Contract. By means thereof, ImmoScout24 will provide the Licensee, in particular, with information on changes with regard to the API.
  2. After the registration, the Licensee can request an API Key. The API Key is Project-specific and may only be used for the use purpose set forth in the request (see Annex Point 7). For any additional use purpose, a separate Key needs to be requested. Several API Keys may be requested in the course of one API registration.
  3. The Licensee must always keep the e-mail address used for registration up to date and notify ImmoScout24 immediately of any changes. If the Licensee fails to do so, declarations to them shall be deemed to have been received if they were sent to the e-mail address last notified to ImmoScout24.

5. Termination

  1. The Use Contract may – if not Pay Use – be terminated by each contractual party at any time without stating reasons. Such termination can be declared in text form (by e-mail). In that case, ImmoScout24 reserves the right to withdraw the license from registered Licensees without further ado.
  2. For Pay Use termination is allowed for both contractual parties with a period of two weeks to the end of a calendar month if not agreed otherwise, especially in the booking. The right for extraordinary termination for cause remains applicable.

The right to extraordinary termination without notice remains unaffected. Cancellations according to this paragraph 2 must be made in writing (by letter or fax).
