Returns identity data from SII (Servicio de Impuestos Internos) for a given RUT. Legal entities only. Source: www.sii.cl PUB_NOMBRES_PJ.

Latinfo identifies the originating government dataset and preserves source evidence and freshness when the publisher exposes them. Verify material decisions with that institution.

Authentication required. REST requests use a Latinfo API key. The interactive console builds the authorization header and does not store the key.

Provenance and limitations

Coverage varies by country and public source. A missing field is not evidence that the underlying fact does not exist. Public registries may be delayed or contain source errors; inspect the returned evidence and source date before relying on a result.
