# ONE Engine Moving Average Calculator (Parameter=8, Tier 1)

> ONE Engine Moving Average Calculator (Parameter=8, Tier 1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0016/call, status unknown (last checked 2026-11-03).

Calculates trailing moving averages over a numeric series using a window parameter of 8, returning basic diagnostic output at Tier 1 of 10.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-moving-average-calculator-parameter-8-tier-1-bc30b99f -d '<json body>'
```

Example prompt: Can you calculate the trailing 8-period moving average for this list of numbers: [10, 20, 15, 30, 25, 40, 35, 50, 45, 60]?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost deterministic moving average computation on a numeric series with a fixed window of 8, especially in agent workflows where reproducibility and low latency matter. Prefer this over general-purpose statistical APIs when you want predictable, pay-per-call pricing via x402 on Base.

## Known failure modes

- Input series shorter than the window parameter (8) may return partial or empty results
- Non-numeric values in the input array will cause a validation error
- Missing or malformed request body returns a 400 error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Rate limiting or quota exhaustion may return a 429 error

## How this service works

Deterministic numeric series utility: Calculate trailing moving averages; parameter=8. Tier 1/10 provides progressively richer diagnostics.

## Output

Returns an array of trailing moving average values computed over the input numeric series using a window of 8, along with basic Tier 1 diagnostic information about the computation.
