SIC Filings

Every filing made at the Superintendencia de Industria y Comercio (SIC) gets a radicado: a consumer-protection lawsuit, a complaint, a trademark or patent application, a competition matter, a petition. The SIC shows the progress of a filing to its parties: who filed what and when, each action the Superintendencia took, the autos and resoluciones it issued, and the documents behind each step. Look up a filing by its year and number together with the document of one of its parties (the plaintiff, the defendant, the applicant). Croma returns every action and keeps a byte-identical copy of every document, so the links keep working even if the source’s own links change. POST /co/sic-tramites/case/v1 One filing, by its year and number and the document of one of its parties.

Field	Type	Notes
`year`	integer	Required. Year of the radicado, four digits, e.g. `2025` for `25-194793`.
`case_number`	string	Required. Number of the radicado without the year, e.g. `194793`.
`case_control`	string	Optional control characters of the radicado, up to 2. Most have none.
`document_type`	enum	Document type of the party. Default `NIT`.
`document_number`	string	Required. Document number of one of the filing’s parties. A NIT goes without its check digit.
`include_documents`	boolean	`true` returns every document with a stored copy; `false` returns the actions alone, much faster. Default `true`.
`cache`	boolean	Set to `false` to read the filing again instead of reusing an answer from the last hour. Default `true`.

Returns found, the filing echoed back (year, case_number, case_control, document_type, document_number), procedure, filed_at, last_action_at, total_actions, actions[] and administrative_acts[]. Each action carries sequence_number, procedure, event, action, direction (EN incoming, SA outgoing, TR internal), date, party (sender or addressee), parent_case, joined_cases, has_documents and documents[]. Each document and each administrative act carries label, file_name, content_type, bytes, document_url (Croma’s stored copy, byte-identical to the original) and source_document_url (the Superintendencia’s own link); acts also carry act_type (AU auto, SE sentencia, RE resolución), act_number and issued_at.

Reading every document of a filing can take a few minutes. This is an async job: by default the request waits inline and returns { data }, or you can poll or pass a callback_url. Pass include_documents: false for the actions alone, which answers in seconds.
