# ONE Engine Text Clean Pack Tier 7

> ONE Engine Text Clean Pack Tier 7 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Cleans and normalizes input text using a tier-7 processing pack, returning cleaned text output via a pay-per-call x402 API on Base.

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-clean-pack-tier-7-8ac9afc8 -d '<json body>'
```

Example prompt: Clean up this raw text for me — it has weird whitespace, stray characters, and inconsistent formatting: 'Hello,,  world!  This is   a messy    string...'

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call text cleaning or normalization step within an autonomous agent pipeline — particularly when operating on Base with x402 micropayments and you want a lightweight utility with no subscription overhead. Prefer this over heavier NLP services when the task is purely cleaning/normalizing text rather than semantic analysis or generation.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Payment not fulfilled via x402 returns a 402 Payment Required response
- Text too long may exceed processing limits
- Malformed JSON body returns a 400 error
- Network or worker timeout for very large inputs

## 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 tier number (7) and a 'result' field with the cleaned and normalized version of the input text string after tier-7 processing rules are applied.
