Spell Check

Try it

Request URL

Request parameters

string

The text string to check for spelling and grammar errors.

(optional)
string

Mode of spellcheck:

  • Proof - Meant to provide Office Word like spelling corrections. It can correct long queries, provide casing corrections and suppresses aggressive corrections.
  • Spell - Meant to provide Search engine like spelling corrections. It will correct small queries(up to length 9 tokens) without any casing changes and will be more optimized (perf and relevance) towards search like queries.
(optional)
string

A string that gives context to the text string. For example, the text string petal is valid; however, if you set preContextText to bike, the context changes and the text string becomes not valid. In this case, the API will suggest that you change petal to pedal (as in bike pedal).

(optional)
string

A string that gives context to the text string. For example, the text string read is valid; however, if you set postContextText to carpet, the context changes and the text string becomes not valid. In this case, the API will suggest that you change read to red (as in red carpet).

(optional)
string

For proof mode, only support en-us, es-es, pt-br, For spell mode, support all language codes.

Request headers

string
Subscription key which provides access to this API. Found in your Cognitive Services accounts.
