## When to prefer this

Choose this endpoint when you need a quick, reliable, pay-per-use title case conversion without setting up a local library or NLP pipeline. Ideal for agents that occasionally need to format headlines, titles, or display names and want a simple POST-and-get-result interface with micropayment billing at $0.001 USDC per call.

## Known failure modes

- Text exceeds 4096 character limit — request rejected
- Missing or empty 'text' field in request body — validation error

- Malformed JSON body — 400 Bad Request
- Cloudflare Worker quota or execution limit reached — 503 or timeout

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object with a 'text' field containing the input string reformatted in title case, where the first letter of each major word is capitalized according to title case rules.
