APIVerve Website Readability API vs ProfText

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.

ProfText checks documents for vague language, patterns associated with AI-generated writing, and academic citation validity. Available on the web and through an API, it accepts text and offers a free tier with 30 clarity and detection rules. ProfText says free analysis runs in a browser Web Worker, so text stays on the user’s device and is not retained. The free plan allows unlimited analyses of up to 5,000 characters each, but excludes citation verification, AI rewrites, compliance checks, risk scoring, and shareable report links. Pro costs €9.99 per month and raises the analysis limit to 100,000 characters. It adds citation cross-checks against OpenAlex, rewrites with tone controls, compliance flags, risk grading, custom rules, and.txt and.docx uploads. Pro also includes CSV export, priority support, and report links that remain available for 90 days. Enterprise adds REST API access, bulk processing, SSO and team management, and dedicated support at a custom price. The site describes team workflows with roles, document versioning, comments, approvals, and analytics.
