How this service works
Call when an agent needs text rewritten with the lower case transform. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/case-lower first.
Output
Returns the input text with all alphabetic characters converted to lowercase. The output is a plain string matching the input length and structure but with every uppercase letter replaced by its lowercase equivalent.
Example use cases
Normalize user input for search
“Take this search query the user typed — 'BLUE Running SHOES Size 10' — and convert it to all lowercase so I can do a case-insensitive database lookup.”
Lowercase CSV column values
“I have a CSV field value 'New York, NY — UNITED STATES' and I need it lowercased before I store it in the database. Can you do that?”
Sanitize username before registration
“The user wants to register with the username 'JohnDoe42' — can you lowercase it to 'johndoe42' so we store it in a consistent format?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/case-lower?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a guaranteed deterministic, offline lowercase transform with no LLM involvement and no network calls beyond the API itself. Use the free sandbox alternative (POST /v1/sandbox/case-lower) for testing before incurring the $0.001 USDC cost. Choose this over general-purpose LLM text rewriting when you need a pure, predictable case conversion without any AI interpretation or hallucination risk.
Side effects
- Empty string input returns a validation error (minLength: 1 enforced)
- Input exceeding 100,000 characters is rejected (maxLength enforced)
- Payment failure or insufficient USDC balance results in 402 response — use free sandbox endpoint POST /v1/sandbox/case-lower first
- Malformed JSON body returns 400 bad request
