# SIC Filings

> Follow a filing (radicado) at Colombia's Superintendencia de Industria y Comercio as one of its parties: every action, the administrative acts, and every document.

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`. |

```bash theme={"dark"}
curl https://api.croma.run/co/sic-tramites/case/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
        "year": 2025,
        "case_number": "194793",
        "document_type": "NIT",
        "document_number": "1234567890",
        "include_documents": false
      }'
```

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`.

<Note>
  Reading every document of a filing can take a few minutes. This is an [async job](/async-jobs): 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.
