# ONE Engine Text Normalize-Space

> ONE Engine Text Normalize-Space 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).

Normalizes whitespace in a given text string, collapsing or trimming excess spaces.

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-text-normalize-space-dd4dd76b -d '<json body>'
```

Example prompt: Can you normalize the whitespace in this text for me: 'Hello   world,   this   has   too   many   spaces.'?

## When to prefer this

Choose this endpoint when you need a cheap, fast, stateless way to normalize whitespace in arbitrary text strings — especially in agentic pipelines where text cleaning is a preprocessing step. At $0.001 USDC per call via x402 on Base, it suits high-frequency, low-cost automation workflows where paying per call is preferable to running your own infrastructure.

## Known failure modes

- Missing 'text' field in request body returns an error
- Extremely large text strings may time out or be rejected
- Empty string input may return an empty string or an error
- Non-string values for 'text' may cause a validation error

## How this service works

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

## Output

A JSON object containing the key 'text' with the whitespace-normalized version of the input string — multiple consecutive spaces collapsed to single spaces, and leading/trailing whitespace trimmed.
