Data & API

Every score, description, and source on this site is available for research use: as plain files you can load into pandas or R, and as a queryable read-only API covering score history, the sources database, verified policy-initiative records, and per-run provenance. How the scores are constructed is documented in the methodology.

Download the dataset

One HTTP GET each, no key, CDN-served. These files update together, monthly, and their git history makes any past state retrievable by commit hash.

File	Contents
scores.csv	196 countries × six 1–5 scores (quarter-point decimals), last-updated date, data version.
regulation_data.csv	Per-country prose for the five dimensions, key legislation, source URLs, confidence.
history.json	Change-point score snapshots per country; the timeline's raw data.
subscores.json	The four named sub-indicators (integers 1–5) behind each dimension score.
country_iso.json	ISO 3166 alpha-2 / alpha-3 / numeric codes for every dataset country name.

The read-only API

The database behind the site is publicly queryable through PostgREST. The interactive API reference documents every endpoint, column, and filter (generated from the database schema itself), and runs queries against the live API from the browser.

Endpoint	Contents
/public_export	The whole dataset flat: countries × scores × summaries.
/countries	Canonical names, ISO codes, and name aliases.
/country_scores	Current scores, incl. the sub-indicator breakdown (subscores).
/country_summaries	Per-dimension prose, key legislation, raw source list.
/score_history	Every score a country has ever carried, with dates.
/sources_export	The accumulating sources database, with citing countries.
/policy_initiatives	Verified policy-initiative records (OECD.AI / GAIIN).
/research_runs	Provenance: every research run, its model and prompt version.

From your own scripts, authenticate with the public read-only token, in a header or as an apikey query parameter. Add Accept: text/csv for CSV instead of JSON:

curl "https://wlakioilvvuuizxdhsdf.supabase.co/rest/v1/public_export?select=country,iso3,avg_score&order=avg_score.desc.nullslast&limit=10" \
  -H "apikey: sb_publishable_mANlk3lYBOM8DWDKUjvhRg_yq0TyTEM"

Standard PostgREST filter syntax works everywhere: column=eq.value, gte./lte., order=, limit=/offset=, and embedded joins like countries!inner(name). Responses are capped at 1,000 rows per request; page with limit/offset.

The API is infrastructure for research convenience. For archival reproducibility, cite the static files above or keep a copy of your extract.

Recipes

Worked queries that answer real research questions. Open runs the query live in a new tab; the path works as-is in the reference, curl, or your own code.

Attribution & citation

Policy-initiative records include data from the OECD.AI Policy Observatory (Policy Navigator / GAIIN): OECD.AI Policy Observatory, oecd.ai, accessed on the date shown per record.

To cite the map itself, use the Share button in the app for a formatted APA/Chicago/MLA citation of the exact view you're referencing. Scores are model-assigned; the methodology and the research_runs endpoint record how each one was produced. Cite them as estimates, and verify claims against the primary sources each entry links.
