autocomplete - Enforce MapBox Geocoding API to return only results with a zipcode

Question

I'm working with MapBox Geocoding API to have suggestions of addresses in the location search feature of my website.

The following is a sample call:

https://api.mapbox.com/geocoding/v5/mapbox.places/Zur.json?country=ch&limit=5&proximity=8.765.432&language=en-GB&access_token=***

My goal is to enforce the api to return only results that include a zipcode.

For example if I input "Zur" (limiting the search to Swiss) I get the following:

 - Zürich, Zürich, Switzerland
 - Zürich, Switzerland
 - Zürich Airport, Flughafenstrasse, Kloten, Zürich 8302, Switzerland
 - Zurich, Buchs, Zürich 8107, Switzerland

The expected results should be without the first two lines, as they don't have a zipcode.

I tried implementing myself the removal of results without the zipcode on client side (just after I got an answer from the api), but it is a suboptimal solution (for example it doesn't ensure to have enough results).

I was not able to find such feature in MapBox. Is there a better solution out of there?

Answer 1

Just add ?types=address
