    How do I access data using APIs?

    Using APIs

    -

    Coming soon: Intro with short explicit description. APIs - What are they? Borrow from get-started/api-primer.md

    +

    API stands for Application Programming Interface, and is basically “like a digital mediator that enables different software applications to talk to each other and exchange information. It defines the methods, parameters, and data formats you can use to access certain features or retrieve data from an application or service.” (How to Use An API)

    How do I know?

    How do I know what API services are available for a dataset?

    -

    Some but not all datasets have API services that can reproject, resample or reformat files on the server file. This How-To shows how to find which services are available.

    NASA API Examples

    Harmony

    -

    short description, when to use it

    +

    Harmony allows you to seamlessly analyze Earth observation data from different NASA data centers with services that offer data reduction and common access mechanisms across all NASA data centers. There is a python client library called harmony-py that exists as a wrapper for the Harmony services, and this notebook gives a brief introduction to the Harmony API services.

    OPeNDAP

    -

    short description, when to use it

    +

    OPeNDAP, or the Open-source Project for a Network Data Access Protocol, is a data server that allows for accessing scientific datasets through the public internet. OPeNDAP links can be acquired through dataset landing pages or the common metadata repository. For more information, see the OPeNDAP Data Access Client Tutorials.

    earthaccess

    +

    earthaccess is a python library to search, download or stream NASA Earth science data with just a few lines of code that also abstracts a lot of other APIs developed by NASA.

    AppEEARS

    The Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) offers users a simple and efficient way to perform data access and transformation processes. By enabling users to subset data spatially, temporally, and by layer, the volume of data downloaded for analysis is greatly reduced. AppEEARS requests can be submitted in website and via API. In a same way, outputs generated can also be accessed from AppEEARS website and through API. View AppEEARS documentation and API documentation for more information. Additionally, you can work with the data in the cloud using provided S3 links. Visit AppEEARS Data Resources Repository for more tutorials on how to work with AppEEARS programaticaly.
