I am using the Watson Tone Analyzer POST API. If the size exceeds 2500 words(approx 17kb) the API does not consider all the sentences in analysis. Only half the sentences are returned. However, the doc mentions it can take upto 128kb, 1000 sentences at a time. If 128kb is exceeded, 400 bad request error is given. Could someone explain this behavior? On what is this limit imposed? The number of words or number of characters or number of sentences? Also, does it have any Pagination??
