## 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-to-paragraphs-t4-a6d65ec1 -d '<json body>'
```

Example prompt: Take this article text and break it into individual paragraphs for me: [paste up to 50,000 characters of text here].

## When to prefer this

Choose this endpoint when you need a cheap, low-latency, pay-per-call paragraph segmentation utility for autonomous agent pipelines — especially when processing up to 50,000 characters of text and billing per-call via USDC on Base using x402 is preferred over subscription APIs.

## Known failure modes

- Text exceeding 50,000 character limit returns an error or truncation
- Malformed or empty text input returns a validation error
- Payment failure via x402 prevents endpoint access
- Unstructured or whitespace-only text may yield empty or minimal paragraph output
- 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.
