Mock sample for your project: Gateway API

It is important to standardize the process of identification of an individual across healthcare providers, to ensure that the created medical records are issued to the right individual or accessed by a Health Information User through appropriate consent.
In order to issue a Health ID to an individual, one only needs basic demographic details like Name, Year of Birth, Gender. In addition, citizens should be able to update contact information easily.

The following are the specifications for the APIs to be implemented at the Health Repository end if an entity is only serving the role of a HIU. The specs are essentially duplicates from the Gateway and Bridge, but put together so as to make it clear to HIUs which set of APIs they should implement to participate in the network.
The APIs are organized by the flows - identification, consent flow, data flow and monitoring. They represent the APIs that are expected to be available at the HIU end by the Gateway.
For majority of the APIs, if Gateway has initiated a call, there are corresponding callback APIs on the Gateway. e.g for /consents/hiu/notify API on HIU end, its expected that a corresponding callback API /consents/hiu/on-notify on Gateway is called. Such APIs are organized under the Gateway label.
Gateway relevant APIs for HIUs are grouped under Gateway label. These include the APIs that HIPs are required to call on the Gateway. For example, to request a CM for consent, HIU would call /consent-requests/init API on gateway.
NOTE, in some of the API documentations below, X-HIP-ID is mentioned in header (for example in /auth/on-init). These are the cases, when a particular API is applicable for both HIU and HIP (e.g an entity is playing the role of HRP representing both HIU and HIP). If you are only playing the role of HIP, then only X-HIU-ID header will be sent

The following are the specifications for the APIs to be implemented at the Health Repository end if an entity is only serving the role of a HIP. The specs are essentially duplicates from the Gateway and Health Repository, but put together so as to make it clear to HIPs which set of APIs they should implement to participate in the network.

Entity which provides health information aggregation services to customers of health care services.
It enables customers to fetch their health information from one or more Health Information Providers
(e.g., Hospitals, Diagnostic Labs, Medical Device Companies), based on their explicit Consent and to share such
aggregated information with Health Information Users i.e. entities in need of such data (e.g., Insurers,
Doctors, Medical Researchers).

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.

NSDC (https://www.nsdcindia.org) promotes skill development by catalyzing creation of large, quality and for-profit vocational institutions. Skill certificates provided under various NSDC programmes are made available to citizens in their DigiLocker accounts.

This REST API provides searchable access to information about geographical names in the province of British Columbia, including name status and details about the corresponding geographic feature.
Please note that you may experience issues when submitting requests to the delivery or test environment if using this OpenAPI specification in other API console viewers.

With the Movie Reviews API, you can search New York Times movie reviews by keyword and get lists of NYT Critics' Picks.

With the TimesTags API, you can mine the riches of the New York Times tag set. The TimesTags service matches your query to the controlled vocabularies that fuel NYTimes.com metadata. You supply a string of characters, and the service returns a ranked list of suggested terms.
