x402
ONE Engine Numeric Round (T9) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-02).
Rounds an array of up to 1000 numeric values with optional scaling, offsetting, digit precision, and clamping to min/max bounds.

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 scaling, offsetting, and clamping have been applied according to the input parameters.
Example use cases
Financial figure rounding for reports
“I have these raw transaction amounts that need to be rounded to 2 decimal places before I put them in the report: [12.3456, 0.999, 105.5012, 7.0001, 88.8888]. Can you round all of them to 2 digits?”
Clamping sensor readings to valid range
“These sensor readings can only be valid between 0 and 50, but some are out of range — can you clamp and round them all to 1 decimal place? The values are: [-3.2, 24.678, 51.9, 0.0045, 49.999].”
Scaling and rounding a price list by a factor
“I need to apply a 1.15 markup factor to these prices and then round everything to 2 decimal places: [9.99, 24.50, 3.75, 149.0, 0.49].”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/round/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to batch-round, clamp, scale, or offset an array of numbers in a single pay-per-call API call without running local computation — especially useful in autonomous agent workflows on Base/x402 where serverless numeric transforms are needed at low cost ($0.018 USDC per call).
Side effects
- Input array exceeds 1000 elements — request rejected
- Non-finite numbers (NaN, Infinity) in values array cause errors
- Invalid digit precision (negative or non-integer) may cause unexpected output
- min greater than max causes undefined clamping behavior
- Payment failure via x402 returns HTTP 402 before processing
