In their own words
APIVerve Website Readability API
APIVerve Website Readability API analyzes a website and returns its readability score. It accepts webpage input, with API access for submitting requests programmatically, and lists eight readability scores and grade-level analysis. Requests use POST at /v1/websitereadability over HTTPS and require an API key in the x-api-key header; one key works across APIVerve’s 300+ APIs. Each call uses 10 credits from a shared account pool. Responses are available in JSON, XML, YAML, CSV, GraphQL and MCP. A live request tool on the product page can be tried without an API key, and a snippet can embed an interactive form without placing keys in markup. The service also names VerveKit, VerveSheets, automation integrations and Node.js, Python and.NET SDKs. Pricing is freemium: the Free plan provides 200 credits per month, while Starter costs $29.99 a month. The API is listed as online with a 99.9% uptime SLA and typical p50 latency of 1798 ms. APIVerve was founded in 2020 and is headquartered in Lee's Summit, Missouri.
Text Inspector
Text Inspector analyses English text for difficulty, readability, lexical diversity, and CEFR levels. Its overall difficulty score draws on more than 200 metrics, while the CEFR Level Checker gives individual words a level along with their commonness and difficulty. Listed tools include Statistics and Readability, Lexical Diversity, Scorecard, Tagger, EVP, BNC, COCA, Academic Word List and Phrases, Knowledge-Based Vocabulary Lists, and Metadiscourse Markers. An API lets people and organisations add analysis and scoring to their own products. The maker describes it as useful to language professionals, academics, and students preparing teaching materials or tests and evaluating student work. English is fully supported; other languages may receive limited statistics or lexical-diversity information. The Free plan covers 250 words and automatically deletes analysis data after six hours. The Organisation plan allows up to 13,000 words, the largest stated limit. A 30-day trial is listed for API access, which starts from £360 per year.
