Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/uppercase/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, reliable, pay-per-call text uppercasing transformation without setting up your own string processing logic. It is well-suited for autonomous agents that need on-demand text normalization at low cost ($0.03 USDC) without managing infrastructure. Prefer it for moderate-length texts (up to 50,000 characters) where a lightweight, stateless conversion is sufficient.

- Missing required 'text' field in request body — validation error
