## Tools (as reported by the server, not verified)

- `list\_entities`: 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.
- `get\_passport`: Full public fact passport of an entity: attested statements with sources, plus the attestation block \(what the trust level proves, how and when it was verified\).
- `ask`: 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.
- `search\_entities`: 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
- `get\_trust\_ladder`: 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.
- `check\_trust`: 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 \(sufficien
