ApyHub Readability Scores Documents API

What ApyHub Readability Scores Documents API is

ApyHub Readability Scores Documents API measures how easy a document or publicly accessible web page is to read. It returns a readability score, reading level, and text statistics, including counts and average lengths for words, sentences, characters, and paragraphs, plus estimated reading and speaking times. The result also identifies a grade class and a plain-language class, and indicates whether a standard readability threshold is met. English uses the Flesch Reading Ease formula by default; German uses the Wiener Sachtextformel. The file endpoint accepts PDF, DOC, and DOCX uploads up to 100 MB per request, while the URL endpoint scores public web pages. The API can be used through ApyHub MCP for AI-agent content review. ApyHub says it does not log request or response bodies, but keeps API call metadata for 90 days.
