Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use. ECHO provides integrated compliance and enforcement information for over 1 million regulated facilities nationwide.
DFR Rest Services provide multiple service endpoints, to retrieve detailed facility location, enforcement, compliance monitoring, and pollutant information for any single facility. See the Detailed Facility Report (DFR) Help Page (https://echo.epa.gov/help/reports/detailed-facility-report-help) for additional information on the DFR. Additionally, a Data Dictionary (https://echo.epa.gov/help/reports/dfr-data-dictionary) is also available.
There is one primary service end point, get_dfr, that provides all available DFR data. All other service end points that are exposed, will return data on a single section of the DFR.

The Semantic API complements the Articles API. With the Semantic API, you get access to the long list of people, places, organizations and other locations, entities and descriptors that make up the controlled vocabulary used as metadata by The New York Times (sometimes referred to as Times Tags and used for Times Topics pages).
The Semantic API uses concepts which are, by definition, terms in The New York Times controlled vocabulary. Like the way facets are used in the Articles API, concepts are a good way to uncover articles of interest in The New York Times archive, and at the same time, limit the scope and number of those articles. The Semantic API maps to external semantic data resources, in a fashion consistent with the idea of linked data. The Semantic API also provides combination and relationship information to other, similar concepts in The New York Times controlled vocabulary.

The Books API provides information about book reviews and The New York Times bestsellers lists.
