score_readabilityread-only Compute readability scores for English text: Flesch Reading Ease, Flesch-Kincaid grade, Gunning Fog, SMOG, Coleman-Liau, ARI and a consensus grade, with plain-English interpretation, text statistics (words, sentences, syllables, reading and speaking time) and the sentences longer than a threshold. Read-only; the text is scored in memory and never stored or logged. Same engine as the PlainGrade JSON API (POST /v1/score).
