Count

Count occurrences characters words or lines in a text

POST/v1/count/string

Counts how many times a text appears (case can be ignored), how many characters there are (with or without spaces), how many words or how many lines. Occurrences do not overlap by default, so aa in aaaa is 2; switch overlapping on to get 3. One final line break does not add a line.

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
