Commitment 26
Relevant Signatories commit to provide access, wherever safe and practicable, to continuous, real-time or near real-time, searchable stable access to non-personal data and anonymised, aggregated, or manifestly-made public data for research purposes on Disinformation through automated means such as APIs or other open and accessible technical solutions allowing the analysis of said data.
We signed up to the following measures of this commitment
Measure 26.1 - Measure 26.2 - Measure 26.3
In line with this commitment, did you deploy new implementation measures (e.g. changes to your terms of service, new tools, new policies, etc)?
If yes, list these implementation measures here
Do you plan to put further implementation measures in place in the next 6 months to substantially improve the maturity of the implementation of this commitment?
If yes, which further implementation measures do you plan to put in place in the next 6 months?
Measure 26.1
Relevant Signatories will provide public access to non-personal data and anonymised, aggregated or manifestly-made public data pertinent to undertaking research on Disinformation on their services, such as engagement and impressions (views) of content hosted by their services, with reasonable safeguards to address risks of abuse (e.g. API policies prohibiting malicious or commercial uses).

QRE 26.1.1
Relevant Signatories will describe the tools and processes in place to provide public access to non-personal data and anonymised, aggregated and manifestly-made public data pertinent to undertaking research on Disinformation, as well as the safeguards in place to address risks of abuse.
Meta provides public access to public data that can support research through several tools and processes:

- Meta Content Library and API: Meta maintains the Meta Content Library User Interface (UI) and the Meta Content Library API, research tools that allow qualifi ed researchers to explore and analyse publicly accessible data across Facebook and Instagram. The Meta Content Library UI provides a comprehensive, visual, searchable collection of publicly accessible content, while the Meta Content Library API enables programmatic queries of the data and deeper analysis in a secure cleanroom environment.

- Ad Library and API: Meta maintains the Ad Library and the Ad Library API — publicly available tools that allow for multi-criteria search of ads delivered across Meta technologies.
- Additionally, Meta publishes aggregated data on content enforcement in its publicly available Transparency Centre reports (https://transparency.fb.com/data/).

Safeguards to address risks of abuse:
The Meta Content Library and API implement multiple, layered safeguards, such as controlled access, prohibition of misuse, privacy protection and ongoing oversight.

The Ad Library is a public transparency tool. The Ad Library API implements safeguards including verified access, policy-based restrictions, and technical abuse prevention.
QRE 26.1.2
Relevant Signatories will publish information related to data points available via Measure 26.1, as well as details regarding the technical protocols to be used to access these data points, in the relevant help centre. This information should also be reachable from the Transparency Centre. At minimum, this information will include definitions of the data points available, technical and methodological information about how they were created, and information about the representativeness of the data.
Meta Content Library and API: Meta publishes comprehensive documentation about the data available through the Meta Content Library and API on Meta's Developer Documentation portal, which is reachable from the Meta Transparency Centre. This documentation includes definitions of available data points, the scope of the data (including eligibility criteria for content inclusion), technical protocols for accessing the data (including API documentation), and a changelog documenting product and data changes per release.

Ad Library and API: The dedicated website for the Ad Library allows users to search all of the ads currently running across Meta technologies. Meta publishes information about ways-of-access and the data points available in the Ad Library and Ad Library API on Meta’s Transparency Center, the Ad Library Overview and FAQ page and the Ad Library API page.
