Open Data

Every published record in the archive is available as structured JSON, free to reuse. Use it for research, visualizations, apps, or your own collection tools.

What is included

• product.json, company.json, profile.json, review.json, competition.json, catalog.json, article.json, story.json, media.json: one file per record type.
• taxonomies.json: materials, play styles, and categories.
• manifest.json: release version, generation date, record counts, and a SHA-256 checksum for each file.
• changelog.json: records added, removed, and changed in each release.

Only published records are exported. Email addresses are removed. Relations between records (a product’s company, a review’s product) are expressed as references to record IDs and URLs.
