# ONE Engine T5 Control-Clean Text Normalizer

> ONE Engine T5 Control-Clean Text Normalizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).

Normalizes and cleans text using a T5-based control-clean model, removing noise and standardizing formatting up to 50,000 characters.

## 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-t5-control-clean-text-normalizer-e1db09f5 -d '<json body>'
```

Example prompt: Can you clean and normalize this messy scraped text for me — remove noise, fix formatting, and standardize it so it's ready for further processing? Here's the text: 'Th1s is   an EXamplE   of nois3y,   badly-formatted   text !!'

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call text normalization without committing to a subscription service. Ideal for agent pipelines that process variable volumes of noisy text (scraped content, OCR output, user input) and want to pay only for what they use via x402 on Base. Best for preprocessing steps before embedding, summarization, or classification.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Payment not provided or insufficient USDC balance — 402 response returned
- Empty or null text input — validation error
- Model inference timeout for very complex or dense text
- Malformed JSON request body — 400 error

## 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 and cleaned version of the input text, processed by a T5 control-clean model to remove noise, fix formatting, and standardize the content.
