A JSON object containing the uppercased version of the submitted text, with all alphabetic characters converted to their capital equivalents and other characters preserved.
Example use cases

“I need to uppercase this product SKU before storing it: 'sku-ab123-widget-pro' — can you convert it to all caps?”
Standardize headers in a report

Prepare text for case-insensitive matching
“Can you uppercase this search query before I run it against my index: 'new york city office locations open tuesday'?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/uppercase/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call uppercase text conversion without standing up your own infrastructure, especially in agentic pipelines on Base that already use x402 micropayments. Ideal for preprocessing steps where you need reliable, hosted text normalization at low cost ($0.018 USDC per call) without managing API keys.
