How it works


Get Your API Keys

API requests will be rejected if the request header does not include the API access key provided by Sinay.


Define an area

There are three ways to define an area

  • Around a position, from a center (longitude, latitude) and a radius, we will find and return data for stations which are in a circle around the coordinates (radius in km)
  • From a station name, we will return data for this station name, and an error if the station name does not exist
  • From a GeoJSON, we will find and return all stations found in the GeoJSON area, Only Geometry objects are allowed (not Feature and FeatureCollection)


Set the time and the model

Time interval

You must define the time interval for which you want to retrieve data. As our data are separated in calendar month, you can only define the year and the month for start and end time. The accepted format is yyyy-mm, for example 2022-01.


Model type

You must select the model type. You can retrieve them using the retrieve models endpoint.





  • You will find a list of stations we found for your request.
  • For each station, you will find the list of retrieved data with associated metadata.

Api units

An header named x-api-units will be added in each answer to tell you how many units the request cost you. If the request is done in dry run, you won’t be charge, but you will be able to see how many it would cost you
