How this service works
Call when an agent needs lines of text transformed with uppercase. No network. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/lines-uppercase first.
Output
Returns the input text with every line converted to uppercase characters. The response preserves line structure and only changes character casing.
Example use cases
Normalize CSV header row casing
“I have a CSV where the column headers are mixed case — can you uppercase all the lines so the headers become consistent? Here's the content: 'name,age,city
john,30,new york
jane,25,boston'”
Prepare text for legacy system ingestion
“Our old mainframe only accepts uppercase input. Take this multi-line address block and convert every line to uppercase: '123 Main St
Springfield
IL 62701'”
All-caps banner text for print layout
“I need the text for our poster to be all caps on each line. Here's the copy: 'grand opening
saturday july 12
doors open at 9am' — can you uppercase each line?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/lines-uppercase?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, no-LLM, exact uppercase transformation of multiline text at a fixed $0.01 USDC cost. Prefer the free sandbox endpoint POST /v1/sandbox/lines-uppercase for testing without payment. Choose this over LLM-based casing when you need guaranteed all-caps output without inference variance or token costs.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Insufficient USDC balance causes a payment failure (402 response)
- Network timeout if the service is temporarily unavailable
