## When to prefer this

Use this endpoint when you need a quick, lightweight lexical diversity computation for a single text passage and are operating in an x402 micropayment environment. Suitable for NLP pipelines, content quality checks, or writing analysis tools that need vocabulary richness metrics without a full NLP platform.

## Known failure modes

- Empty or missing text input returns an error
- Extremely short texts may yield unreliable diversity scores
- Non-textual or malformed input may cause processing failure
- Payment failure via x402 protocol blocks the request
- Rate limiting may occur for high-frequency calls
