## 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 orbuis-summarize-text-pay-per-call-x402-7bc7b434 -d '<json body>'
```

Example prompt: Can you summarize the following article in bullet points, keeping it under 80 words and in English? [paste of article text]

## When to prefer this

Choose this endpoint when you need a lightweight, pay-as-you-go text summarizer with no account setup — especially in agent workflows where cost-per-call billing via USDC/x402 is preferred, or when you want bullet-point vs paragraph style control and optional multilingual output. Ideal for single-call, low-friction summarization without committing to a subscription or managing API keys.

## Known failure modes

- Text too short (below minLength of 1) or too long (above 12,000 characters) — validation error
- maxWords out of range (below 20 or above 400) — validation error
- Payment failure over x402 (insufficient USDC balance or unsupported chain) — 402 response
- Invalid style enum value — request rejected
- Network timeout if on-device model is briefly unavailable
