Use the Data Destinations Availability API to check if the data in your data destinations is up to date. The API checks if the data for a given date on your end (your S3, etc.) is identical to the most updated data in Singular's database. 

For each data destination you have configured, the API returns is_all_sources_updated (true or false). It also returns is_updated for each data connector included in the data destination export.

Note that if data_date is omitted, the API checks data for yesterday.

Data Destinations Availability Endpoint

Sample Query (Python)

import requests
url = "https://api.singular.net/api/v2.0/data_destinations_availability_status"
queryparams = {"api_key": "<API_KEY>", "data_date": "2026-08-20"}
response = requests.get(url=url, params=queryparams)

You can also call the endpoint directly in a browser or with curl:

curl "https://api.singular.net/api/v2.0/data_destinations_availability_status?api_key=<API_KEY>&data_date=2026-08-20"

Query Parameters

Sample Output

The following sample shows the result for one data destination, which contains two data connectors. In this sample, is_updated is false for all of the data connectors and therefore is_all_sources_updated is false.
