## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kihustle-readability-fog-index-calculator-a199fbb7 -d '<json body>'

Example prompt: Can you check the readability of this paragraph for me and give me its Fog Index score? 'Artificial intelligence systems, while computationally sophisticated, increasingly permeate quotidian human activities, necessitating interdisciplinary comprehension of their societal ramifications.'

## When to prefer this

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.
