Available Smart City Real Time Data Endpoints

FIWARE offers a huge amount of Open Data that is available for you for free at https://data.lab.fiware.org. This section covers the most important real-time information that you will be able to find in all the cities that participates in the FIWARE initiative.

Santander (Spain)

The city of Santander in Spain, relies on FIWARE for publishing its smart city real time data. For this purpose, the city has two different NGSI endpoints using NGSI v1 and NGSI v2 respectively.

The There is one NGSI v1 service is deployed on http://mu.tlmat.unican.es:8099/ and queried using can be queried sending NGSI queries to the queyContext service using HTTP POST requests. Thise This service responses with a contextResponses node containing a list of contextElement, each representing a entitity or sensor. For these entities, it is included the type, the id, and a list of attributes, which is different depending on the type of the entities.
