# ONE Engine T9 Text Trim Normalizer

> ONE Engine T9 Text Trim Normalizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-02).

Normalizes and trims text by applying T9-style text normalization to remove extraneous whitespace and clean up input strings.

## 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-t9-text-trim-normalizer-b62da563 -d '<json body>'
```

Example prompt: Can you trim and normalize this text for me — remove any extra whitespace or formatting noise: '  Hello,   world!  This   has   lots  of   spaces.  '

## When to prefer this

Choose this endpoint when you need a lightweight, cheap ($0.018 USDC per call), pay-per-use text normalization and trimming operation without spinning up your own preprocessing pipeline. Ideal for autonomous agents that need to clean text programmatically at low cost using x402 micropayments on Base.

## Known failure modes

- Text exceeds 50000 character limit — request rejected with validation error
- Empty or missing 'text' field — returns 400 bad request
- Payment not provided or insufficient — returns 402 Payment Required
- Malformed JSON body — returns parsing error
- Network timeout on Cloudflare Worker edge — intermittent 503

## How this service works

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

## Output

Returns a JSON object containing the normalized, trimmed version of the input text with extraneous whitespace removed and the string cleaned up according to T9 normalization rules.
