Building an engine?
Build it on our catalog.

We maintain a catalog of 100+ European sovereign technology suppliers. For each one: the raw state of every datum and a sovereignty judgment computed from it. Consume it through one scoped API — instead of rebuilding the catalog yourself.

What you get

• The facts — for every supplier, three sovereignty dimensions (corporate jurisdiction, data residence, technological dependencies), each as a [value, state] pair.
• The judgment — a per-dimension and aggregate SEAL level (0–3), recomputed live from facts and supplier overlay, under an explicit, auditable capping policy.
• Supplier overlay — what each supplier has confirmed, annotated or filled in (a confirmation can raise a datum's cap; it never silently overwrites).

Adding an engine is one operation: we issue you an API key with a scope. No direct access to the database or the JSON — everyone reads through the API, on the same terms.

Even if you compete with us

Yes — even if the engine you are building competes with our own configurator, you are welcome as a consumer of the catalog. The catalog is meant to be neutral infrastructure: we keep the facts and the judgment honest for every engine that reads them. Our edge is the engine we build on top, not gatekeeping the substrate.

The API

Base URL https://api-catalogo.sovrafit.eu · authenticate with the bearer key we issue you. Your key carries a scope; the response adapts to it.

Scope	Returns	For
facts	identity + merged facts + annotations + validata_da_fornitore	an engine that judges on its own
facts+judgment	the above + the Sovrafit SEAL giudizio	engines that buy the judgment
+rails	enables attributed referral links — not the commercial terms	monetizing through the rails

Endpoints

• GET /v1/catalog — list suppliers (id + name) visible to your scope.
• GET /v1/catalog/{supplier_id} — one supplier: facts, annotations, and the judgment if your scope includes it.

# one supplier, with the judgment (scope facts+judgment)
curl -H "Authorization: Bearer <your-key>" \

With facts the giudizio is omitted — you bring your own confidence policy over the raw states. The commercial layer never appears, in any scope.
