# ONE Engine Number Power

> ONE Engine Number Power 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 result of raising a base number to an exponent (base^exponent) and returns the numeric result.

## Facts

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-number-power-92e67bea -d '<json body>'
```

Example prompt: What is 2 raised to the power of 8? Use the ONE Engine power utility to calculate it.

## When to prefer this

Choose this endpoint when an AI agent needs to perform exponentiation as part of an automated pipeline and either lacks native math capabilities or needs a consistent, pay-per-call utility. Particularly useful for agents built on platforms with limited arithmetic operations, or when you want to keep math operations as discrete, auditable API calls. At $0.001 per call, it's cost-effective for occasional programmatic exponentiation needs.

## Known failure modes

- Missing base or exponent fields returns an error
- Extremely large exponents may cause numeric overflow or precision loss in floating-point
- Non-numeric values for base or exponent will likely return a validation error
- Network or worker timeout for unusual edge cases

## How this service works

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

## Output

Returns a JSON object with a single `value` field containing the numeric result of base raised to the exponent power (e.g. {"value": 256} for base=2, exponent=8).
