Intesta

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.

{
  "type": "object",
  "properties": {},
  "title": "list_entitiesArguments"
}

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).

{
  "type": "object",
  "properties": {
    "entity_domain": {
      "title": "Entity Domain",
      "type": "string"
    }
  },
  "required": [
    "entity_domain"
  ],
  "title": "get_passportArguments"
}

Ask a natural-language question about an entity (max 2000 characters). The answer is built strictly from the entity's attested fact passport; each returned fact carries source, attestation status and validity dates. A refusal means the passport has no such fact — the engine never guesses.

{
  "type": "object",
  "properties": {
    "entity_domain": {
      "title": "Entity Domain",
      "type": "string"
    },
    "question": {
      "title": "Question",
      "type": "string"
    }
  },
  "required": [
    "entity_domain",
    "question"
  ],
  "title": "askArguments"
}

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.

{
  "type": "object",
  "properties": {
    "query": {
      "title": "Query",
      "type": "string"
    },
    "limit": {
      "default": 20,
      "title": "Limit",
      "type": "integer"
    }
  },
  "required": [
    "query"
  ],
  "title": "search_entitiesArguments"
}

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.

{
  "type": "object",
  "properties": {},
  "title": "get_trust_ladderArguments"
}

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.
