18  Pinterest

Pinterest provides no UGC data transparency resource enabling programmatic access to public content in any assessed region. In the EU, it offers curated datasets to selected researchers under its own conditions, but this does not meet the criteria applied in this analysis. Advertising transparency is assessed through the Pinterest Ads Repository in Brazil and the EU, but no equivalent resource is available in the UK. Pinterest’s REST API v5 is limited to authenticated account management and does not support programmatic extraction of public user-generated content in any jurisdiction. As no graphical interface exists for this purpose either, UGC data transparency is classified in the Not Available band across all regions. On the advertising side, Brazil and the EU fall within the Negligible range: the public Ads Repository provides GUI-based access to active and inactive ads, discloses advertiser identities and delivery periods, supports filtering by date range and thematic category, and returns consistent results. However, it offers no API access and does not allow structured data extraction, as current API versions have deprecated the ad repository endpoints available in earlier iterations. As such, basic GUI-level ad browsing in Brazil and the EU remains the only practically useful feature. Additional limitations include the absence of payer disclosure, engagement metrics, AI content labeling, and advertiser verification data.
