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 input text transformed to uppercase. The response follows an open schema so the uppercased result string is included in the response body, likely under a key such as 'result' or 'text'.
Example use cases
Normalizing user input for comparison
“Take this user-submitted form field value — 'john doe from new york' — and convert it to all caps so I can do a case-insensitive database lookup.”
Formatting display headers
“I need this section title 'quarterly revenue summary by region' converted to all uppercase so I can use it as a formatted report header.”
Standardizing identifiers in a dataset
“I have a list of product codes like 'abc-123-xyz' and 'def-456-uvw' — can you uppercase them all so they match our internal standard format?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-normalize/uppercase/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, low-cost, pay-per-call text uppercasing operation within an autonomous agent pipeline that supports the x402 payment protocol on Base. It is ideal for agents that process arbitrary text strings up to 50,000 characters and need deterministic, side-effect-free case normalization without managing a self-hosted solution.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- Missing or empty 'text' field returns a validation error
- Payment failure via x402 (insufficient USDC balance or network issues on Base) blocks the call
- Malformed JSON request body results in a 4xx error
- Cloudflare Worker cold-start or downtime may cause transient 5xx errors
