USDA PubAg API supports the integration of apps for accessing and searching a database of agricultural publications. The database contains over 41,000 full-text journal articles by USDA staff and includes over a million citations. Access to the free web-based API requires an API key that is tied to a maximum hourly request rate of 1000 units. Permissions must be sought for higher rates of hourly requests. Released in a fully-supported and documented mode, the USDA PubAg API is flexible to either JSON or XML formats.
We've added six APIs to the ProgrammableWeb directory today including APIs for Agriculture, Nutrition, Screenshots, and other categories. Additionally, four SDKs for use with Synapse Payments have recently been listed in the SDKs and Libraries portion of the directory. Here's a look at what's new.
