Example prompt: Can you check the readability grade of this paragraph: 'Automation enables entrepreneurs to scale their operations without proportional increases in manual labor, thereby optimizing time allocation across high-leverage activities.'?

## When to prefer this

Use this endpoint when you need a quick, low-cost automated readability grade on a piece of text without setting up a local NLP library. It is ideal for agents that need to validate content clarity, enforce readability standards in content pipelines, or help content creators target a specific reading level. Prefer this over general-purpose LLM-based readability judgment when you want a consistent, objective numerical grade.

## Known failure modes

- Empty or missing 'text' field causes a processing error
- Extremely short text (1-2 words) may yield unreliable or null grade scores
- Very long text inputs may be truncated or time out
- Non-text or binary input will result in an error response
- Network or payment failure returns a 402 or 5xx status
