ONE Engine Numeric Percent Change Top-10
x402
ONE Engine Numeric Percent Change Top-10 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-02).
Computes percent-change metrics for an array of numeric values and returns the top 10 results, with optional scaling, filtering, and rounding controls.

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 top 10 numeric percent-change results computed from the input array, potentially filtered by min/max bounds, limited to the specified size, scaled by a factor, offset by a constant, and rounded to the specified number of decimal digits.
Example use cases
Stock price movement ranking
“I have a list of stock closing prices for the past month — [210, 198, 225, 180, 245, 200, 190, 230, 175, 260, 215, 205] — can you calculate the percent changes and show me the top 10 biggest movers, rounded to 2 decimal places?”
Sales performance comparison
“Here are our monthly sales figures across 20 products: [5000, 4800, 5200, 3900, 6100, 4700, 5400, 6200, 3800, 5900, 4600, 5100, 6300, 4200, 5700, 4900, 6000, 4100, 5500, 4400]. Calculate percent changes and give me the top 10 performers, filtering out anything below 2% change.”
Sensor data anomaly prioritization
“I've got 50 sensor readings from our IoT devices and need to know which ones changed the most. Here's the array: [102,98,105,97,115,101,99,120,96,118,103,100,125,95,117,104,99,122,94,116,106,101,128,93,119,107,102,130,92,121,108,103,132,91,123,109,104,134,90,125,110,105,136,89,127,111,106,138,88,129]. Return the top 10 percent changes scaled by a factor of 1.5.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/percent-change/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call computation of percent changes ranked by magnitude from a numeric array of up to 1000 values, especially in autonomous agent workflows on Base/x402 where low cost per call ($0.03 USDC) matters. It is preferable over building custom logic when you need server-side ranking, filtering, scaling, and rounding in a single call without managing your own compute infrastructure.
Side effects
- Array exceeds 1000 values — request rejected
- Non-finite numbers (NaN, Infinity) in values array — validation error
- Missing required 'values' field — 400 bad request
- Payment failure via x402/Base — 402 Payment Required
- Empty array provided — may return empty or error response
- Invalid parameter types (e.g. string instead of number) — schema validation error
