ONE Engine Array Average
x402
ONE Engine Array Average 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).
Computes the arithmetic mean of a provided array of numbers, returning the count and average value.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with 'count' (number of values in the input array) and 'value' (the arithmetic mean of those numbers). Example: {"count": 3, "value": 20}.
Example use cases
Average product prices in catalog
“I have a list of product prices — 9.99, 14.99, 4.50, 22.00, and 7.75 — can you calculate the average price for me?”
Mean student test score
“Here are the test scores from my class: 88, 72, 95, 61, 84, 90, 77. What's the average score across all of them?”
Summarize sensor readings
“I collected these temperature readings throughout the day: 68.2, 71.5, 74.0, 69.8, 72.3 — what's the mean temperature and how many readings did I take?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/array/average?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a quick, cheap, stateless arithmetic mean computation without standing up any server-side logic. At $0.001 USDC per call via x402 on Base, it is ideal for autonomous agents that process numeric arrays on demand and need deterministic, low-latency results. Prefer it over general-purpose code execution when you just need a mean and count without extra overhead.
Side effects
- Empty array input — endpoint requires a non-empty array; returns error if values array is missing or empty
- Non-finite numbers (Infinity, NaN) in the array — schema requires finite numbers only
- Malformed request body — missing 'values' property or wrong data type returns a 400-level error
- Payment failure — x402 payment of $0.001 USDC not settled correctly blocks the call
