## 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-segment-pack-t4-0188201f -d '<json body>'
```

Example prompt: Take this article text and segment it into tier-4 packed chunks so my pipeline can process each piece independently: 'Artificial intelligence is transforming industries at an unprecedented pace, reshaping how businesses operate and how consumers interact with technology.'

## When to prefer this

Choose this endpoint when you need tier-4 text segmentation and packing specifically within a pay-per-call autonomous agent pipeline on Base using x402 micropayments, and when a low-cost ($0.0018 USDC) utility call is acceptable for structured text chunking.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Text exceeding length limits may be truncated or rejected
- Payment failure via x402 results in 402 Payment Required response
- Malformed JSON body returns a 400 Bad Request
- Cloudflare Worker timeout for very large text inputs

## How this service works

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