ONE Engine Numeric Clamp (T3)
x402
ONE Engine Numeric Clamp (T3) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Clamps an array of numbers to a specified min/max range, optionally applying scaling, rounding, and offset transformations.

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 numbers after clamping to [min, max], with optional scaling by factor, shifting by offset, and rounding to the specified number of digits. Output size can be controlled via the size parameter.
Example use cases
Clamping sensor readings to valid range
“I have these temperature sensor readings: [22.4, -999, 37.1, 150.0, 25.6] — clamp them all between 0 and 50 and round to 1 decimal place.”
Normalizing ML confidence scores
“Can you clamp these model confidence scores [1.3, 0.0, -0.2, 0.87, 1.05, 0.44] to the range 0 to 1, keeping 4 decimal places?”
Constraining financial values with scaling
“Take these raw bid prices [0.5, 12.3, 7.8, 99.9, 3.2], apply a factor of 1.1 and an offset of -1, then clamp everything between 0 and 20.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/clamp/t3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cheap, fast, pay-per-call numeric clamping operation as part of an autonomous agent workflow, especially when you also need compound transformations (scaling, offset, rounding) applied in the same call. Prefer it over writing custom code when operating in x402-enabled agentic pipelines on Base that benefit from micropayment-gated utility APIs.
Side effects
- Empty or missing 'values' array returns an error
- Array exceeds 1000 elements — rejected with validation error
- Non-finite values (NaN, Infinity) in input cause failure
- Invalid type for numeric parameters (e.g. string instead of number)
- Payment failure via x402 prevents processing
- Malformed JSON body returns 400-level error
