Get information about the structure of a data set, its data points and any linked data sets.

GET https://sub-domain.cloudtables.io/api/1/dataset/:id/schema

curl \
	-G \
	-d 'key=:apiKey' \
	https://sub-domain.cloudtables.io/api/1/dataset/:id/schema

Get the structure of a given data set where:

• :apiKey is the API key to use for access (see below)
• :id is the data set id (a UUID), per the /datasets API. The data set ID can also be found in the Data set inspector of the Data tab for the data set.

Query parameters

• key string Required Header
  The API key which will allow access. Note that this option can be also be provided as an HTTP header (also with the name key).

Example

The following example shows an API return for a CloudTables application that has two data sets available, one which contains information about Airports and another about Flights:
