## 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 automata-maintenance-helper-text-summarization-351cf836 -d '<json body>'
```

Example prompt: Can you summarize this article by pulling out the first 3 sentences? Here's the text: 'El cambio climático es uno de los mayores desafíos del siglo XXI. Los científicos advierten que las temperaturas globales seguirán aumentando. Se requieren medidas urgentes para mitigar sus efectos. Los gobiernos del mundo deben actuar de manera coordinada.'

## When to prefer this

Choose this endpoint when you need a fast, deterministic, extractive summary that selects the literal first N sentences of a text without generating any new content. It is ideal when faithfulness to the original wording is critical, when you need exact character-level offsets for highlighting or citation, or when you want a reproducible, auditable summary. Prefer alternatives if you need abstractive summarization, importance-ranked sentence selection, or summaries longer than 5 sentences.

## Known failure modes

- Sentence count outside 1–5 enum — rejected with schema validation error
- Empty or missing text field — rejected with validation error
- Payment failure or insufficient USDC balance — 402 Payment Required returned
- Network or upstream service error — 5xx response
