88# Delphi's COVID-19 Data Sources and Signals
99
1010Delphi's COVID-19 Surveillance Streams data includes the following data sources.
11- Data from these sources is expected to be updated daily. You can use the
12- [ ` covidcast_meta ` ] ( covidcast_meta.md ) API endpoint to get summary information
11+ Data from most of these sources is typically updated daily. You can use the
12+ [ ` covidcast_meta ` ] ( covidcast_meta.md ) endpoint to get summary information
1313about the ranges of the different attributes for the different data sources.

1515The API for retrieving data from these sources is described in the
16- [ COVIDcast API endpoint documentation] ( covidcast.md ) . Changes and corrections to
17- data in this API are listed in the [ API changelog] ( covidcast_changelog.md ) .

1919To obtain many of these signals and update them daily, Delphi has written
2020extensive software to obtain data from various sources, aggregate the data,
2121calculate statistical estimates, and format the data to be shared through the
22- COVIDcast API. This code is [ open source and available on
23- GitHub] ( https://github.com/cmu-delphi/covidcast-indicators ) , and contributions
24- are welcome.
