How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the processed array of numbers, each rounded to the specified number of decimal digits, optionally scaled by a factor, shifted by an offset, and clamped within min/max bounds. Output size can also be controlled.
Example use cases
Rounding financial transaction amounts
“I have a list of raw transaction values [15.6789, 0.1234, 99.9951, 7.005] — can you round each one to 2 decimal places so they're ready for display?”
Normalizing sensor readings with scaling
“Take these raw temperature readings [100.456, 200.789, 150.123], multiply each by 0.1, then round to 1 decimal place and clamp everything between 10 and 20.”
Preparing scores for leaderboard display
“I have 5 player scores [88.4321, 72.9987, 95.1111, 60.5678, 81.2222] — round them all to the nearest whole number so I can show them on a leaderboard.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/round/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call numeric rounding and normalization utility that also supports scaling, offsetting, and clamping in a single step, without standing up your own math service. Ideal for AI agents running in serverless pipelines on Base that need deterministic numeric transformations at $0.0015 per call.
Side effects
- Array exceeds 1000 element limit — request rejected
- Non-finite values (NaN, Infinity) in the input array — may cause errors or be filtered
- Invalid digits parameter (negative or non-integer) — malformed request error
- Payment failure via x402 — 402 response, call not executed
- Empty values array — may return empty result or error
