Introduction

NextBillion’s Multi-Geocoding API allows you to find the geo-coordinates, and addresses(Place, Locality, administrative area) of POIs from multiple data sources. It also enables you to easily manage the places’ information to improve the utility of the search results based on custom business needs. For instance,

Create custom locations that your business needs
Get combined results for a searched text from all data sources i.e default and custom datasets
Override the results of default search provider in case of duplicate or similar places and prioritize custom places in search results

POST

Search Place

The method enables searching for known places from multiple data sources

Use this method to find known places in default or your own custom (proprietary) dataset and get a combined search result. It accepts free-form, partially correct or even incomplete search texts. Results would be ranked based on the search score of a place.

PUT

Update Place

The "Update Place" method allows businesses to update the attributes of an existing place

This method allows you to update the attributes of custom places. In effect, updating a place replaces the current information in search results with the updated information associated with the specific docID. Use this method to enhance the accuracy/usability of your search results with respect to the default dataset to suit your business needs.

If you want to prioritize a particular result in your search results, update the ‘score’ of that specific place.
Alternatively, you can block places which are no longer needed by setting their status: ‘disable’.
