# IGAC Street Names Search

`POST /co/igac/street-names-search/v1`

## Request

- Base URL: `https://api.croma.run`
- URL: `https://api.croma.run/co/igac/street-names-search/v1`
- Auth: HTTP bearer

The street names (nomenclatura vial) IGAC draws on the cadastral map of a municipality in Colombia, by words of the name when given, each with where it sits as GeoJSON in WGS84. About 150,000 names. Served by Croma.

**Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`.

## Headers

- `Idempotency-Key` string

## Request body

- object
  - `municipality_code` string, required: Five-digit DANE code of the municipality, e.g. `17013` for Aguadas or `52001` for Pasto.
  - `query` string: Optional words matched against the name, e.g. `el porvenir`.
  - `page` integer: 1-based page number for paginated results.
  - `per_page` integer: Results per page (1-50); every result carries its geometry.

## Response `200`

Successful response

- IgacStreetNamesSearchResponse
  - `data` IgacStreetNamesSearchData, required
    - `as_of` string, nullable, required: How current the data in this response is.
    - `municipality_code` string, required
    - `query` string, required
    - `total` number, required: Matches, counted up to 1000.
    - `total_is_exact` boolean, required: False when more than 1000 match: `total` is then 1000, and the pages go on.
    - `page` number, required
    - `per_page` number, required
    - `total_pages` number, required: Pages over `total`; there are more when `total_is_exact` is false.
    - `count` number, required
    - `results` object[], required
      - `id` string, required: `<zone initial>:<municipality_code>:<text>`.
      - `text` string, required: The street's name or nomenclature as IGAC prints it on the map.
      - `zone` 'urban' | 'rural', required
      - `department_code` string, required
      - `municipality_code` string, required
      - `part_count` number, required
      - `geometry` object, nullable, required: The feature's geometry as GeoJSON in WGS84, exactly as IGAC draws it; referential, it does not certify boundaries.
        - `type` string, required: `Polygon`, `MultiPolygon`, `LineString`, `MultiLineString` or `Point`.
        - `coordinates` unknown, required
      - `geometry_url` string, nullable, required: Set when the geometry is too large to carry inline (a rural zone can run to tens of MB): the same GeoJSON geometry, kept by us, and `geometry` is null.
