What it is

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.
