Check

Test whether an array holds a value

POST/v1/check/array/has/value

Returns true or false and how many items match. Compare exactly, or by text (contains, starts with, ends with), optionally ignoring case and surrounding spaces. For an array of objects pick the property to compare; an object without it never matches.

Responses

Status	When it happens
200	Successful Response
400	The body respects the operation schema, but the use case rejected it. Each problem is one ApiError entry
413	The request is larger than the request size limit of the API allows
422	The body does not respect the operation schema. Each problem is one ApiError entry with the code validation_error
500	Something failed inside the server and was not an input problem. The same envelope, errors may be empty
