The Superintendencia de Seguridad Social (SUSESO) supervises Chile’s social security: medical leave and the COMPIN, work accidents and occupational diseases under Ley 16.744 and the mutualidades, family allowance, the compensation funds (CCAF) and their social credit, welfare services, and more. Its dictámenes settle how those rules apply, many in answer to a worker, an employer or an institution. About 16,100 are published, from 1971 to today. Each one here comes with its number and date, who it is addressed to, SUSESO’s summary, its topics and descriptors, the legal sources it rests on, the units that issued it, the dictámenes, circulars and provisions SUSESO relates to it, any files it attaches, its full text, and a byte-for-byte copy of its page at SUSESO. Search by number, year, date, topic or a related dictamen, or with free text that reaches into the summary and the body of every dictamen. Search first, then read one dictamen in full.
The whole source, organized and ready to query: every endpoint on this page answers in milliseconds. Every response carries as_of: how current the data is. How datasets work.

​
Search the dictámenes

POST /cl/suseso/dictamenes-search/v1 Dataset One search over every dictamen SUSESO publishes since 1971, filtered by number, year, date, topic or a related dictamen.
Returns as_of (how current the data is), the applied filters, total and total_is_exact, page, per_page, total_pages, count and results[], most recent dictamen first. Every result carries id (SUSESO’s permanent id for the dictamen, e.g. 758965), number (as SUSESO publishes it, e.g. O-01-S-00582-2025 or 4268-1988), title, year, issued_date, recipient (who it is addressed to), summary (SUSESO’s summary, which most dictámenes before 2019 lack), topics, descriptors, legal_sources, departments (the SUSESO units that issued it), action, criterion and validity (when SUSESO states them), related_circulars_text and related_oficios_text (the circulars and oficios it agrees with, as written), other_fields (any other labelled field), related_dictamenes and related_circulars (each with its id, title and issued_date), related_legislation, attachments (each file with its title, name, content_type, bytes, document_url and source_document_url), official_url (the dictamen’s page at SUSESO), document_url (Croma’s byte-for-byte copy of that page), source_document_url and document_versions. Fields SUSESO does not state are null.
Search results leave out the text. query still matches against it, so a phrase from the body finds the dictamen; read the text itself with the SUSESO Dictamen endpoint.
SUSESO adds to a dictamen’s related dictámenes and circulars as new ones appear. Croma reads new dictámenes every day and every dictamen again once a month.

​
One dictamen, in full

POST /cl/suseso/dictamen/v1 Dataset
Returns as_of, found, dictamen_id and dictamen, which carries everything the search returns plus content, a window onto the full text with text, offset, total_length, has_more and next_offset. Every result carries id (SUSESO’s permanent id for the dictamen, e.g. 758965), number (as SUSESO publishes it, e.g. O-01-S-00582-2025 or 4268-1988), title, year, issued_date, recipient (who it is addressed to), summary (SUSESO’s summary, which most dictámenes before 2019 lack), topics, descriptors, legal_sources, departments (the SUSESO units that issued it), action, criterion and validity (when SUSESO states them), related_circulars_text and related_oficios_text (the circulars and oficios it agrees with, as written), other_fields (any other labelled field), related_dictamenes and related_circulars (each with its id, title and issued_date), related_legislation, attachments (each file with its title, name, content_type, bytes, document_url and source_document_url), official_url (the dictamen’s page at SUSESO), document_url (Croma’s byte-for-byte copy of that page), source_document_url and document_versions. Fields SUSESO does not state are null.
Long dictámenes are read a range at a time: send offset and limit, then pass the response’s next_offset back as offset until has_more is false.
An id SUSESO has not published returns found: false with HTTP 200, not an error.
