# ONE Engine Numeric Absolute Top-10 Filter

> ONE Engine Numeric Absolute Top-10 Filter 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).

Returns the top 10 absolute values from an array of numbers, with optional scaling, rounding, and range filtering.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-numeric-absolute-top-10-filter-93306e66 -d '<json body>'
```

Example prompt: From this list of values [-450, 12, 380, -900, 27, -55, 610, -300, 88, -720, 5, 430], give me the top 10 by absolute magnitude, rounded to 2 decimal places.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.03/call), pay-per-use computation of top absolute values from a numeric array without standing up your own infrastructure. Ideal for autonomous agents that occasionally need numeric ranking by magnitude and want to avoid managing compute resources. Best when the array is under 1000 elements and results need optional scaling/rounding in one pass.

## Known failure modes

- Input array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in input array cause validation errors
- Missing required 'values' field returns 400 error
- Payment not included or insufficient USDC causes 402 Payment Required
- Network timeout on Cloudflare Workers edge

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the top 10 numbers from the input array ranked by absolute value, potentially filtered by min/max bounds, scaled by a factor, offset by a constant, and rounded to a specified number of decimal digits.
