## 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-7-18867e22 -d '<json body>'
```

Example prompt: Run this text through the ONE Engine text transform pack at tier 7 and give me the result: 'The quick brown fox jumps over the lazy dog.'

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call text transformation operation and are operating within an x402-compatible agent framework on Base. It is well-suited for autonomous agents that require micropayment-gated text processing without committing to subscription pricing. Prefer it when tier-7 specific transformation behavior is needed within the ONE Engine text-transform-pack suite.

## Known failure modes

- Payment not included or insufficient USDC — 402 Payment Required response
- Empty or missing 'text' field in request body — likely a 400 or malformed response
- Service unavailable on Cloudflare Workers edge — 503 or timeout
- Tier output undefined for certain input edge cases — may return generic or empty result
- x402 payment protocol not supported by client — payment handshake fails

## 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 (7) and a tier-dependent transformed result of the input text. The exact nature of the transformation is tier-specific and determined by the service's internal logic for tier 7.
