Our verdict on ApyHub Readability Scores Documents API
ApyHub Readability Scores Documents API is built for developers adding readability analysis to content review, editorial quality assurance, SEO, or publishing workflows. It accepts uploaded PDF, DOC, and DOCX files, as well as publicly accessible webpage URLs, through separate API endpoints. Results include Flesh-Kincaid Reading Ease and Wiener Sachtextformel scores, alongside word, sentence, character, and paragraph statistics. The API also provides reading-time and speaking-time estimates, average word, sentence, and paragraph lengths, and English or German analysis-language options.
Pricing is structured around monthly atom allowances and API capacity. The free Starter plan includes 3,000 atoms per month, one API key, five requests per second, one team member, and MCP access. The Pro plan costs $16 per month and raises the allowance to 100,000 atoms, with 10 API keys, five requests per second, five team members, top-ups available anytime, and MCP access. Pro+ costs $42 per month, includes 500,000 atoms, 10 API keys, five team members, top-ups available anytime, MCP access, and a 10-request-per-second limit. The paid tiers suit teams processing more documents or requiring greater request capacity.
Its main strength is focused API coverage: developers can send either files or public URLs and receive both formula-based scores and granular measurements for downstream workflows. That makes it a practical fit when readability data needs to become part of an existing application or publishing process. The trade-off is its API-only positioning and narrower language scope. Teams seeking programmatic English or German analysis should find the plan structure easy to map to usage, while buyers wanting a standalone writing environment or broader language coverage should consider a different type of tool.
