# Research

> Answer an open question from live sources and return a cited report in Markdown.

Ask an open question and get back a written report in Markdown with numbered
citations, plus the list of sources behind it. This is a research pass over
live sources, not a lookup against a registry: a call typically takes 10-30
seconds.

## Research a question

`POST /global/research/v1`

| Field   | Type   | Notes                                                          |
| ------- | ------ | -------------------------------------------------------------- |
| `query` | string | **Required.** 10-2,000 chars. The question, in plain language. |

```bash theme={"dark"}
curl https://api.croma.run/global/research/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "query": "¿Qué cambios trajo la Ley 2195 de 2022 en materia de responsabilidad de personas jurídicas en Colombia?" }'
```

| Field            | Notes                                                                         |
| ---------------- | ----------------------------------------------------------------------------- |
| `query`          | Echoes the question asked.                                                    |
| `report`         | The report in Markdown. Bracketed numbers such as `[1]` index into `sources`. |
| `sources`        | The pages the report drew on, each with `title` and `url`.                    |
| `pages_analyzed` | How many pages were read.                                                     |

<Note>
  A report is a starting point, not a citation. Verify anything you act on
  against the primary source — for Colombian case law and public records, the
  country guides return the record itself.
