The core mission of Software Heritage is to collect, preserve and share all software that is publicly available in source code form. Our ambition is to build a long term common infrastructure, to support a variety of applications in the area of cultural heritage, industry and research. For this reason, Software Heritage is established as a non-profit initiative, preserving our software commons for the benefit of all.
More precisely, usage restrictions are justified by:
The Software Heritage archive is a very big data set, comprising billions of individual files and tens of billions of relationships. The public API we provide is specifically designed to allow pointwise access to the data, and is not suitable for massive data extraction. Hence, if you need to obtain a significant subset of the archive data, please refrain from abusing the API, and contact us to explore alternative solutions.
ethical and legal reasons, involving in particular the protection of personal data
The Software Heritage archive collects publicly available source code, and its development history, from a variety of public sources. Any personal information that may be contained in the source code or in the development history, will hence be collected in the archive. The content of the archive being publicly accessible, you may get personal information from the archive too. We explicitly ask you to refrain from misusing any such personal information. Mass mailing software developers is a well known example of misuse that is clearly unacceptable, but there may be many other ones. We may update these terms to explicitly forbid some of these misuses, but you should not consider that whatever is not explicitly forbidden is implicitly blessed: as a rule of thumb, if you have in mind a particular use of personal information which would bother you as a developer, that is a good indicator that you should abandon the idea there and then.
The precise terms and conditions follow. If you are entering this agreement on behalf of a company or other legal entity, you represent that you have the authority to bind such entity to the following terms and conditions. If you do not have such authority or if you do not agree with the following terms and conditions, you are not entitled to use the Software Heritage API
The Software Heritage’s Application Programming Interface, called simply “API” in the following, is the set of methods and protocols that allow to access the Archive and browse its content.
The Software Heritage archive, referred to simply as “Archive” in the following, contains all the source code collected by Software Heritage, as well as all related information collected or produced by Software Heritage, like revisions, releases, file contents and project metadata, as well as additional factual information that may include license information.
2. Accessing the archive
If you respect all the terms of the present agreement, you are granted free use of the public API to access the contents of the Archive, either directly, or through a program, with the following provisions.
2.1 No massive data extraction
Use of the public API to extract significant parts of the contents of the Archive is not authorized. If you need access to significant part of the Archive, please contact us to explore alternative ways to achieve your goals.
2.2 Quota and other technical limitations
3. Using the content of the archive
3.1 Personal data
Software in the Archive may contain personal information such as, but not limited to, developer names and email addresses.
Any systematic use of third party personal information that would cause unjustified prejudice to the very people that built the software commons that are preserved by the Archive is forbidden and will be considered a breach of this agreement. This includes, but is not limited to:
use of the information in a way that would violate people’s privacy or security, or to transmit and send any unsolicited requests, be them commercial material or not (or any other similar solicitation)
building developer profiles to be used without the developer’s consent
In addition, use of personal information may be subject to legal regulations that apply to you, independently of how you assembled it, and you are solely responsible of any violations that may result from your use of the information that you got from the Archive.
The Archive contains a variety of metadata related to the source code, like provenance information and harvesting time, or computed information like file type, file length and programming language. This information may be returned as part of the results of a request through the API. Such metadata is considered factual, not covered by copyright, and may be freely used, as long as you comply with article 3.1 of the present terms and conditions.
3.3 No endorsement
You may not publicly represent or imply that we participated in, supported, or approved the way you use the content of the Archive, in particular when such a use is unlawful.

Software Heritage may provide automatically derived information on the software license(s) that may apply to a given software component, but it makes no claim of correctness and the license information provided does not constitute legal advice. You are solely responsible for determining the license, or other rights that apply to any software component in the Archive, and you must abide by its terms.
