How this service works
Title-case text for agents. Call this when you need headline-ready casing for titles, product names, or UI labels mid-workflow. Returns structured JSON with the title-cased string and a tiny receipt schema. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
A structured JSON object containing the title-cased version of the input string, returned synchronously after a successful $0.001 USDC micropayment via x402.
Example use cases
Formatting article headlines in a CMS pipeline
“I'm generating blog post titles programmatically and need them all properly title-cased — can you convert 'how to build a restful api with node.js' to title case?”
Normalizing product names in a catalog
“We have product names coming in all lowercase from our database, like 'wireless noise cancelling headphones pro' — can you format that in proper title case for our storefront?”
Preparing chapter titles for an ebook
“I need to format this chapter title in title case before publishing: 'a journey through the mountains of northern patagonia'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/title-case?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs deterministic title-case formatting inside a workflow without installing an NPM/PyPI library, managing an API key subscription, or writing custom capitalization logic. It is ideal for serverless or sandboxed agent environments where dependencies are restricted, and for one-off or low-volume formatting tasks where a $0.001 pay-per-use model is more cost-effective than a subscription. It differs from the sibling Delx Sentence Case endpoint, which applies sentence-level rather than word-level capitalization.
Side effects
- Input text exceeds 100,000 character limit — request rejected with a validation error
- Payment of $0.001 USDC not completed or x402 handshake fails — result not returned
- Empty or missing `text` field in request body — may return an error or empty result
- Malformed JSON request body — returns a parsing or validation error
- Network timeout or service unavailability — connection error with no result
