Hi @Nils_w,

you could use the pois endpoint and pass the city geometry and bus_stops as filter
There are also some examples in the source repository.

Hi @amandus ,

is there a way how I can get the city geometry? And does the filter input need to be JSON format like this: {“bus_stops”} ?

best regards

Nils

You have to extract that somewhere else e.g. from OSM and need to pass it as GeoJSON (best simplify the geometry or just take the bbox)

No. Please read the examples and documentation.
E.g. the help button for request:

grafik
grafik853×412 29.7 KB

The category ids can be requested from the endpoint or you can take a look at the this documentation

See above,

These are the examples from the documentation:

#### JSON bodies for POST requests
##### Pois around a buffered point
{
  "request": "pois",
  "geometry": {
    "bbox": [
      [8.8034, 53.0756],
      [8.7834, 53.0456]
    ],
    "geojson": {
      "type": "Point",
      "coordinates": [8.8034, 53.0756]
    },
    "buffer": 250
  }
}

##### Pois given categories
{
  "request": "pois",
  "geometry": {
    "bbox": [
      [8.8034, 53.0756],
      [8.7834, 53.0456]
    ],
    "geojson": {
      "type": "Point",
      "coordinates": [8.8034, 53.0756]
    },
    "buffer": 100
  },
  "limit": 200,
  "filters": {
    "category_ids": [180, 245]
  }
}

##### Pois given category groups
{
  "request": "pois",
  "geometry": {
    "bbox": [
      [8.8034, 53.0756],
      [8.7834, 53.0456]
    ],
    "geojson": {
      "type": "Point",
      "coordinates": [8.8034, 53.0756]
    },
    "buffer": 100
  },
  "limit": 200,
  "filters": {
    "category_group_ids": [160]
  }
}

##### Pois statistics
{
  "request": "stats",
  "geometry": {
    "bbox": [
      [8.8034, 53.0756],
      [8.7834, 53.0456]
    ],
    "geojson": {
      "type": "Point",
      "coordinates": [8.8034, 53.0756]
    },
    "buffer": 100
  }
}

##### Pois categories as a list
{
    "request": "list"
}

This is the example you are looking for:


##### Pois given categories
{
  "request": "pois",
  "geometry": {
    "bbox": [
      [8.8034, 53.0756],
      [8.7834, 53.0456]
    ],
    "geojson": {
      "type": "Point",
      "coordinates": [8.8034, 53.0756]
    },
    "buffer": 100
  },
  "limit": 200,
  "filters": {
    "category_ids": [180, 245]
  }
}

This is the category id for bus_stop : 588
How it would look like in a request:
"filters":{"category_ids":[588]}
Is that still giving bad request?

Well,
this seems to work but my polygon geometry is too large.

What are the restrictions on that?
