Server instructions

The continuously verified register of official European public data. Start with search_entries (filter access_level=direct for sources whose data is one call away). get_entry returns the Access Contract: ranked, runnable actions (downloads, verified requests). related_entries and find_joinable_sources traverse the register graph — two sources sharing a join key (SIRET, NUTS, GSS, …) can be joined on it.

Known tools 8

search_entries

Search the verified register of official European public-data APIs, datasets and portals.

Inferred read-only

get_entry

One entry's full record: metadata, license, verification state, and the Access Contract — a ranked list of actionable URLs (direct downloads, verified runnable requests, specs).

Inferred read-only

related_entries

An entry's graph neighborhood: containment relations (portal ⊃ dataset, service → dataset), same-publisher siblings, and the join-key identifiers its fields carry (with fan-out counts).

Inferred read-only

find_joinable_sources

Every register source whose data carries a given join-key identifier (e.g.

Inferred read-only

plan_query

PLAN a query WITHOUT running it: which source it would hit, the exact upstream request, how many requests, roughly how long (from that source's own measured latency, or null when nothing has been measured — never a guess), which fields would NOT resolve, and which filters cannot be pushed upstream and would be applied locally over a bounded window.

Inferred read-only

run_query

RUN a query against a live-tier source and get real rows back, with the exact upstream request used.

Inferred read-only

cite_query

CITE a query: run it and persist an immutable evidence manifest (query spec, upstream request, retrieval time, result hash, license).

Inferred read-only

subscribe_to_changes

SUBSCRIBE to a source: returns its change-feed URL (RSS, no account needed) plus the recent change events — verification failures, schema changes, deprecation.

Inferred read-only
