How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the lowercased (and T9-normalized) version of the input text string, up to 50,000 characters.
Example use cases
Normalizing user-submitted form input
“Take this user-submitted address field and convert it all to lowercase so I can store it consistently: 'Suite 4B, 123 Main STREET, New York, NY 10001'”
Preprocessing text before keyword matching
“I need to normalize this product description to all lowercase before running keyword search on it: 'Premium ORGANIC Coffee Beans — DARK Roast, Single Origin ETHIOPIA'”
Standardizing log entries for comparison
“Convert this server log snippet to lowercase so I can compare it against my pattern library: 'ERROR: Disk USAGE Exceeded THRESHOLD on Node-07 at 14:32:01 UTC'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/lowercase/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call lowercase/text normalization operation without standing up your own infrastructure, especially in agent workflows already using x402 on Base for micropayments. Suitable for preprocessing steps in data pipelines or NLP workflows where consistent casing is required.
Side effects
- Text exceeds 50,000 character limit — request rejected
- Missing required 'text' field in request body — validation error
