# ONE Engine Text Clean Pack Tier 9

> ONE Engine Text Clean Pack Tier 9 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Cleans and normalizes input text using a tier-9 processing level via a pay-per-call x402 micropayment API.

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-9-d722ef1a -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a low-cost ($0.01 USDC), single-call text cleaning or normalization step within an autonomous agent pipeline, especially when operating on Base with x402 micropayment infrastructure. Prefer it for lightweight preprocessing tasks where a cheap, stateless transformation is sufficient and you don't need a full NLP service.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Payment failure via x402 if USDC balance is insufficient
- Network timeout on the Cloudflare Worker edge
- Unexpected characters or very long strings may cause truncation or malformed output
- No schema documentation for what tier 9 specifically does beyond 'tier-dependent output'

## How this service works

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

## Output

A JSON object containing the tier number (9) and a cleaned/normalized version of the submitted text string under the 'result' field.
