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-transform-pack-tier-8-391e467a -d '<json body>'
```

Example prompt: Transform this text using ONE Engine's tier-8 text transform pack: 'The quarterly report shows a 12% increase in revenue across all segments.'

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.0075 USDC) per-call text transformation at tier 8 within the ONE Engine pack, especially in autonomous agent workflows on Base that already use x402 micropayments. Prefer it over heavier NLP APIs when you need fast, programmatic text conversion without complex setup.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Insufficient USDC balance causes x402 payment failure and the call is rejected
- Malformed JSON request body causes a 400-level error
- Rate limiting or worker overload may return 5xx errors
- Ambiguous tier behavior — output format is opaque and tier-specific, so results may be unexpected

## 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 (8) and a 'result' field with the tier-dependent transformed output of the input text string.
