x402
ONE Engine Numeric Round (t2) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0007/call, status unknown (last checked 2026-10-02).
Rounds an array of numeric values with optional min/max clamping, scaling factor, offset, and digit precision control.

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 transformed array of rounded (and optionally clamped/scaled/offset-adjusted) numeric values, reflecting the precision and bounds specified in the request.
Example use cases
Round financial totals for invoicing
“I have a list of invoice line totals like [12.3456, 99.999, 0.005, 44.1] — round each to 2 decimal places so I can display them as currency amounts.”
Clamp and round sensor readings
“I've got raw sensor values [−5.7, 102.334, 50.0, 77.8891] that should stay between 0 and 100 — round them to 1 decimal place and clamp any out-of-range values.”
Normalize scores with offset and scaling
“Take these raw scores [0.234, 0.876, 0.501, 0.128], multiply by 100, add an offset of 5, and round to the nearest whole number so I get clean percentage-style values.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/round/t2?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs lightweight, pay-per-call numeric rounding with optional clamping and scaling, without spinning up a compute environment. Ideal for pipelines where numbers must be cleaned before display or storage, especially when combined with other ONE Engine utility calls in an agentic workflow. Prefer over general-purpose code execution when cost predictability ($0.0007/call) and simplicity matter.
Side effects
- Array exceeds 1000 elements — request rejected
- Non-finite values (Infinity, NaN) in input array cause validation error
- Invalid digits value (negative or non-integer) returns error
- Payment failure via x402 prevents processing
- min greater than max causes undefined or error behavior
