How this service works
Readability metrics: Flesch-Kincaid, word counts
Output
Returns Flesch-Kincaid readability score and word count metrics for the submitted text. The Flesch-Kincaid score indicates reading ease (higher = easier to read) and/or grade level, helping gauge audience suitability.
Example use cases
Blog post readability check
“I just finished writing this blog post — can you run a readability check on it and tell me the Flesch-Kincaid score and word count so I know if it's appropriate for a general audience? Here's the text: 'Starting a garden can seem overwhelming, but with the right tools and a bit of patience, anyone can grow their own vegetables at home.'”
Academic paper complexity assessment
“Can you analyze this paragraph from my research paper and tell me how readable it is using the Flesch-Kincaid metric? I want to know if it's too complex for undergraduates: 'Epistemological frameworks posit that knowledge acquisition necessitates a dialectical interplay between empirical observation and theoretical abstraction, mediated by cognitive schemata.'”
Marketing copy grade level check
“Before I send this product description to our team, can you score its readability with Flesch-Kincaid and give me the word count? The text is: 'Our revolutionary new blender combines cutting-edge motor technology with intuitive design to deliver a seamless blending experience for health-conscious consumers.'”

Endpoint
GEThttps://api.aurenic.org/readability/:b64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, lightweight readability scoring without sending large payloads in a request body — the base64 path encoding makes it easy to call via GET. Ideal for agents doing quick content quality checks at $0.001 per call with no authentication overhead beyond x402 micropayment.
Side effects
- Invalid or malformed base64 encoding in the path parameter returns an error
- Empty or whitespace-only text yields minimal or zero metrics
- Extremely long texts may hit size limits
- Non-text binary content encoded as base64 may produce nonsensical scores
