Example use cases
Blog post complexity check
“I just wrote this intro paragraph for my AI automation guide — can you calculate its Fog Index and tell me if it's too complex for a general audience? Here's the text: 'Leveraging advanced AI orchestration frameworks enables practitioners to systematically automate multifaceted operational workflows.'”
Marketing copy readability audit
“Before I publish this landing page copy, can you run the Fog Index on it to make sure it reads at roughly a high-school level? Text: 'Our platform accelerates revenue generation by synthesizing heterogeneous data streams into actionable business intelligence.'”
Student essay difficulty scoring
“Can you analyze the reading difficulty of this essay excerpt using the Fog Index? I want to know how many years of education someone needs to understand it: 'Epistemological frameworks inherently constrain ontological inquiry, rendering absolute certainty an unattainable philosophical construct.'”
Technical details
Endpoint
POSThttps://kihustle.tech/agents/api/v1/readability-fog-indexWhen to prefer
Choose this endpoint when you need a fast, lightweight Fog Index readability score specifically — particularly for English prose like articles, blog posts, or marketing copy. Prefer it over heavier NLP pipelines when you only need the Gunning Fog metric rather than a suite of readability scores (Flesch-Kincaid, SMOG, Coleman-Liau, etc.).
Side effects
- Empty or missing text field returns an error or zero score
- Extremely short text (fewer than 2 sentences) may produce unreliable or degenerate scores
- Non-English text may yield inaccurate results since Fog Index is calibrated for English
- Very long text inputs may exceed size limits or increase latency
- Malformed JSON request body returns a 400-level error
