## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001 USDC) programmatic keyword density calculation for SEO auditing, content optimization, or automated content pipelines. Prefer it over manual counting or general-purpose NLP APIs when you specifically need keyword density as a ratio within a text block and want a lightweight, pay-per-call model without subscription overhead.

## Known failure modes

- Missing 'text' or 'keyword' field returns an error or unexpected result
- Empty string inputs may produce undefined density values
- Very long texts may hit payload size limits
- Non-English text or multi-word keywords may yield inaccurate density calculations
- Network or payment authorization failure returns 402 or timeout
