# ONE Engine Text Clean Pack Tier 8

> ONE Engine Text Clean Pack Tier 8 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0075/call, status unknown (last checked 2026-10-02).

Cleans and normalizes input text using a tier-8 processing level via a pay-per-call x402-enabled API on Base.

## Facts

- Endpoint: POST https://one-search.one-engine.workers.dev/v2/text-clean-pack/t8?utm_source=zero.xyz
- Price: $0.0075/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02
- Activations on Zero: 0
- Tags: x402

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-8-dd95f5f1 -d '<json body>'
```

Example prompt: Can you clean up this messy text string for me and normalize it — run it through the tier-8 text clean pack: 'Hello,,,   world!!  This is   some  RAW   text...'?

## When to prefer this

Choose this endpoint when you need a cheap, lightweight, pay-per-call text cleaning operation within an autonomous agent pipeline that already handles x402 payments on Base. Ideal for single-string normalization tasks where setting up a heavier NLP service is overkill and cost-per-call economics matter.

## Known failure modes

- Missing or empty 'text' field in request body returns an error
- Payment not included or insufficient USDC triggers HTTP 402 response
- Malformed JSON body causes a parse error
- Very large text inputs may exceed payload limits
- x402 payment on Base network fails if wallet is underfunded

## How this service works

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

## Output

Returns a JSON object containing a 'tier' field (integer, value 8) and a 'result' field with the cleaned/normalized version of the input text after tier-8 processing.
