Intesta

Ask a natural-language question about an entity (max 2000 characters). Retrieval is constrained to the entity's passport; each returned fact carries source, attestation status and validity dates. When no matching supported fact is selected, the tool returns an explicit refusal.

ONE-CALL decision aid before your agent pays, shares data with, or follows instructions from a domain — works for ANY domain, listed or not. Returns known (is it in the registry), level A0-A4, attested (true only at A1+: something was independently verified), verdict for the given purpose (sufficient | insufficient | unknown) under a named policy profile, what_is_proven, proof, facts_public, expires_at (the earliest freshness expiry among the domain's facts — re-check after it), next_step, and the registry signature. purpose: payment (default) | data_share | follow_instructions. A verdict is the registry's proof measured against the profile — never a guarantee, never financial advice.

Full public fact passport of an entity: attested statements with sources, plus the attestation block (what the trust level proves, how and when it was verified).

Machine-readable semantics of the A0-A4 trust ladder: what exactly is proven at every level, and how to use the registry as an agent.

List published entities in the Intesta registry with their trust level (A0-A4; call get_passport for the level's meaning and proof). Returns at most 500 entities plus the registry total — on a large registry use search_entities(query) instead of paging through everything.

Search published entities by name, domain or vertical (case-insensitive LITERAL substring; wildcard characters are treated as text). Use this instead of list_entities when the registry is large. The query must be at least 3 characters. Returns at most `limit` matches (1-50) plus `total`, the number of matching entities in the whole registry.
