Daily API RoundUp: SnapCard, Dandelion Sentiment, Google Cloud Resource Manager

Every day, the ProgrammableWeb team is busy, updating its three primary directories for APIs, clients (language-specific libraries or SDKs for consuming or providing APIs), and source code samples. If you have new APIs, clients, or Source Code examples to add to ProgrammableWeb’s directories, we offer forms (APIs, Clients, Source Code) for submitting them to our API research team. If there’s a listing in one of our directories that you’d like to claim as the owner, please contact us at editor@programmableweb.com.

We’ve added 6 APIs to the ProgrammableWeb directory today in Sentiment, Metadata, and Messaging, as well as other categories. Also added were client libraries for use with Walmart’s Open APIs. Here’s a summary of what is new.


The Dandelion Sentiment Analysis API tells whether the opinion in text is positive, negative, or neutral. Given a short English or Italian sentence, it returns a label representing the identified sentiment, along with a numeric score ranging from strongly positive (1.0) to extremely negative (-1.0).
