Example use cases
Blog post readability check
“I just wrote this blog post draft and want to know how long it is, how many paragraphs it has, and what the top keywords are so I can optimize my SEO — here's the full text: 'Content marketing has become a cornerstone of modern digital strategy. Brands invest heavily in producing high-quality articles, videos, and infographics to attract and retain audiences...'”
Academic paper keyword extraction
“Can you pull out the top keywords from this research abstract and also tell me the word and sentence counts? Here's the text: 'This study examines the relationship between sleep deprivation and cognitive performance in university students. Participants underwent controlled sleep restriction over seven days while completing standardized memory and attention tests...'”
Estimating reading time for newsletter
“I'm putting together a newsletter and want to tell subscribers how long it'll take to read. Can you analyze this text and give me the reading time, plus word and paragraph counts?

Technical details
Endpoint
POSThttps://toll402.dev/v1/t/text_statsWhen to prefer
Use this endpoint when you need fast, deterministic text statistics — word/sentence/paragraph counts, reading time, and keyword extraction — without invoking a heavyweight LLM. It is ideal for content pipelines, editorial tools, and SEO workflows where reproducibility and low cost matter. Prefer this over general LLM summarization endpoints when you specifically need structured numeric metadata about a text rather than a narrative interpretation.
Side effects
- Empty or missing 'text' field returns a validation error
- Extremely large texts may exceed payload limits or time out
- Non-UTF-8 encoded text may cause parsing errors
- Text consisting entirely of stopwords may return an empty keywords list
- Malformed JSON body returns a 400-level error
