## 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-transform-pack-t9-530d3788 -d '<json body>'
```

Example prompt: Transform this text using the ONE Engine T9 tier text transform: 'The quick brown fox jumps over the lazy dog.'

## When to prefer this

Choose this endpoint when you need tier-9 level text transformation from ONE Engine's text-transform-pack, particularly within an agentic pipeline that uses x402 micropayments on Base. Suitable for cost-sensitive, high-frequency per-call text processing workflows where $0.01 USDC per call is acceptable.

## Known failure modes

- Missing or empty 'text' field returns an error or malformed response
- Payment not completed via x402 returns HTTP 402 requiring USDC payment on Base
- Invalid JSON body causes a parse error
- Tier-9 transformation may produce unexpected output if input text is malformed or too long
- Network timeout on Cloudflare Workers edge node

## 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 tier-dependent transformed version of the input text. The exact nature of the transformation is determined by the T9 tier logic on the server side.
