How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the transformed array of numbers after rounding, optional clamping to min/max bounds, scaling by factor, and offset application. The exact response shape may include the processed values array and metadata about the operation.
Example use cases
Round financial price list
“I have a list of raw prices [12.3456, 0.9987, 5.001, 99.999] — can you round them all to 2 decimal places and make sure none go below 0 or above 100?”
Normalize sensor readings
“I've got sensor readings [0.003421, 1.87654, -0.00023, 4.99871] that need to be rounded to 3 decimal places and clamped between 0 and 5 before I store them.”
Scale and round a dataset
“Take these raw values [10, 25, 37, 82, 156], multiply each by a factor of 0.01, then round everything to 4 decimal places so I can use them as normalized scores.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/round/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call numeric rounding and transformation utility without setting up your own compute — especially useful inside autonomous agent workflows on Base where x402 micropayments are already available. Ideal for batch-rounding up to 1000 numbers in a single call with optional clamping and scaling, at $0.001 USDC per call.
Side effects
- Passing more than 1000 values in the array causes rejection
- Non-finite numbers (NaN, Infinity) in the values array may cause errors
- Missing required 'values' field returns a validation error
- Invalid types (e.g. strings in values array) cause schema validation failure
- Payment failure via x402 protocol blocks the call
