How this service works
Call when an agent needs text rewritten with the upper case transform. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/case-upper first.
Output
Returns the input text with every character converted to its uppercase equivalent. The response is a plain transformed string with no metadata, no LLM interpretation, and no network side effects — purely a deterministic case conversion.
Example use cases
Normalize product code formatting
“Take this product code 'abc-xyz-123' and convert it to uppercase so it matches our catalog format.”
Standardize CSV header row
“I have a CSV header row that reads 'name,email,phone,address' — can you convert it to all caps for me?”
Uppercase a legal document clause
“Please rewrite this clause in all uppercase letters: 'the parties agree that this contract shall be governed by the laws of the state of new york.'”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/case-upper?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a guaranteed deterministic, no-LLM, no-network uppercase conversion at a fixed $0.002 USDC cost. It is ideal for pipeline steps where reproducibility and cost predictability matter. Use the free sandbox endpoint POST /v1/sandbox/case-upper first if available. Choose this over LLM-based rewriting when you need pure case transformation without any semantic alteration.
Side effects
- Empty string input rejected (minLength:1 constraint)
- Input exceeding 100,000 characters rejected
- Missing 'text' field in request body returns validation error
- Payment failure or insufficient USDC balance blocks the call
