How this service works
Call when an agent needs text rewritten with the sentence case transform. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/case-sentence first.
Output
The endpoint returns the input text rewritten in sentence case, where only the first letter of each sentence is capitalized and the rest are lowercased. No external network calls or AI models are involved — it is a deterministic, pure string transformation.
Example use cases
Normalize all-caps article headings
“I have a headline written in all caps: 'GLOBAL MARKETS RALLY AS INFLATION FEARS EASE' — can you convert it to sentence case so it reads naturally?”
Fix mixed-case user-submitted content
“A user submitted this feedback in random capitalization: 'THE PRODUCT IS GREAT BUT SHIPPING WAS SLOW. I WOULD BUY AGAIN.' Please rewrite it in sentence case.”
Format exported database text
“I pulled this description from our database and it's in title case: 'The Annual Sales Report Covers Revenue Growth And Market Trends.' Can you convert it to sentence case?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/case-sentence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, offline sentence case transformation with no reliance on an LLM or external network. It is ideal for normalizing text at scale where consistency and low latency matter. Prefer the free sandbox endpoint (POST /v1/sandbox/case-sentence) for testing before paying. Use this paid endpoint when the sandbox is unavailable or when you need guaranteed production-grade processing.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Malformed JSON body results in a 400 bad request
- Payment not provided or insufficient USDC (must be exactly $0.004) results in 402 Payment Required
