Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/text/title-case?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, cheap, single-call title case conversion without setting up a local NLP library — especially in autonomous agent pipelines where microtransaction-based pay-per-call pricing via x402 on Base is already supported. Ideal for formatting titles, headings, or labels at scale without a subscription.
Side effects
- Missing or empty 'text' field returns an error or empty result
- Extremely long strings may be rejected or truncated
- Payment failure via x402 prevents the call from completing
- Network timeout on the Cloudflare Worker edge node
