Example use cases

Blog post readability check

“I just wrote this intro paragraph for my blog about side hustles — can you tell me the Fog Index so I know if it's too complex for a general audience? 'Building passive income streams requires disciplined systematization of recurring revenue mechanisms and iterative optimization of monetization funnels.'”

Marketing copy simplification audit

“Before I publish this ad copy, can you run the Fog Index on it to see if it's accessible to everyday readers? Here's the text: 'Our proprietary algorithmic framework facilitates unprecedented scalability of your entrepreneurial endeavors through synergistic automation architectures.'”

Educational content grade-level check

“I'm writing a guide for beginners and want to make sure it's not too hard to understand — what's the Fog Index for this sentence: 'Automation tools can systematically execute repetitive digital workflows, substantially reducing operational overhead for independent practitioners.'?”

When to prefer

Choose this endpoint when you need a quick, affordable per-call Fog Index computation without setting up your own NLP pipeline. Ideal for content workflows that require automated readability gating — e.g. checking blog posts, marketing copy, or educational material before publication. Prefer over general-purpose LLM readability assessments when you need a deterministic, standardized metric rather than a qualitative opinion.

Side effects

Empty or missing 'text' field returns an error response
Extremely short text (fewer than 2 sentences) may yield unreliable or zero scores
Non-string input types may cause a processing failure
Very large text inputs may time out or exceed payload limits
Malformed JSON body returns a 4xx error
