7.- Mbook API

Mbook API is an application program interface defined as set of services, protocols, and tools for building software third party client applications according with the licensing model.

7.1 Mbook API. Using our API:

7.1.1. Your End Users. THE LICENSEE will require your end users to comply with (and not knowingly enable them to violate) applicable law, regulation, and the Terms.

7.1.2. Permitted Access. THE LICENSEE will only access (or attempt to access) an API by the means described in the documentation of that API. If Mestrelab assigns you developer credentials (e.g. client IDs), you must
use them with the applicable APIs. You will not misrepresent or mask either your identity or your API Client’s identity when using the APIs or developer accounts.

7.1.3. Non-Exclusivity. The Terms are non-exclusive. You acknowledge that Mestrelab may develop products or services that may
compete with the API Clients or any other products or services.

7.2. API Limitations. Mestrelab sets and enforces limits on your use of the API (e.g. limiting the number of API requests that you may make or the number of users you may serve. You agree to, and will not attempt to circumvent, such limitations documented with each API. If you would like to use any API beyond these limits, you must obtain Mestrelab express consent so using the Mbook API without an API license or performing more request per unit of time defined in your purchasing conditions will also lead to a revocation of your license.

7.3. API Prohibitions. When using the Mbook API, you may not (or allow those acting on your behalf to):

  •  Sublicense an API for use by a third party. Consequently, you will not create an API Client that functions substantially the same as the APIs and offer it for use by third parties.
  •  Perform an action with the intent of introducing to Mestrelab products and services any viruses, worms, defects, Trojan horses, malware, or any items of a destructive nature.
  • Defame, abuse, harass, stalk, or threaten others.
  • Interfere with or disrupt the API or the servers or networks providing the API.
  • Reverse engineer or attempt to extract the source code from any API or any related software.
  • Use the APIs for any activities where the use or failure of the APIs could lead to death, personal injury, or environmental damage.
  • Remove, obscure, or alter any Mestrelab terms of service or any links to or notices of those terms.



MESTRELAB and THE LICENSEE will have the right to consider this contract terminated by any of the causes established in legislation and, in particular, by a breach of these General Terms and Conditions. Using the Mbook API without an API license or performing more request per unit of time defined in your purchasing conditions will also lead to a revocation of your license. In case of noncompliance by THE LICENSEE, MESTRELAB will have the right to exercise its right to terminate the contract with immediate effect and without notice in those cases in which such breach constitutes a violation of the intellectual property rights held by MESTRELAB over the software. In any other case of breach by THE LICENSEE, a notice period of 30 days will apply and THE LICENSEE will have no right to any kind of compensation. During this notice period THE LICENSEE will have the opportunity to remedy the breach to the satisfaction of MESTRELAB. Such termination does not preclude the right by MESTRELAB to legal action. In the case of breach by MESTRELAB, in accordance with these General Terms and Conditions, THE LICENSEE will have the right to terminate the contract with a notice period of 30 days.



The duration of the license is annual and without geographical limits unless otherwise specified in site, campus or corporate national licenses.



These General Terms and Conditions are set in the framework of the Spanish law and the parties agree to refer any controversies arising from these General Terms and Conditions to the courts at Santiago de Compostela. THE LICENSEE expressly renounces any other jurisdiction which could be applicable to THE LICENSEE.



If any clause of these General Terms and Conditions was declared void, the remaining clauses will remain in force and will be interpreted according to the intention of the parties and to the
purpose of these General Terms and Conditions. MESTRELAB will have the right to waiver any of the rights and faculties derived from this document. Such waiver will in no case imply any subsequent waiver unless otherwise admitted by MESTRELAB in writing. These General Terms and Conditions are displayed in English.



Where the MESTRELAB software uses third party packages or services necessary to perform certain actions, and where these third party packages require their End User License Agreement to be agreed to explicitly, these End User License Agreements are available in the License’s folder in the installation programme. If you require MESTRELAB to provide you with a copy of such licenses prior to the acceptance of this license, please send an email to legal@mestrelab.com.
