## 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-source-bounded-summary-a4060af6 -d '<json body>'
```

Example prompt: Summarize the following text in Spanish and show me the exact quotes from the source that back up each point in the summary: [paste of article text up to 4000 characters].

## When to prefer this

Choose this endpoint when you need a summary that is strictly grounded in the source text — i.e., every claim in the summary must be traceable to a verbatim quote from the input. Ideal for legal, journalistic, or research contexts where hallucination or external fact injection is unacceptable. Prefer over generic summarization APIs when auditability and citation are required. Supports Spanish and English output. Best for short-to-medium texts up to 4000 characters.

## Known failure modes

- Text shorter than 1 character or longer than 4000 characters returns a validation error
- Unsupported language code outside 'es' and 'en' returns an error
- Payment of 0.4 USDC not received or rejected returns HTTP 402
- Empty or whitespace-only text may produce degenerate summaries
- Very short texts may yield a summary nearly identical to the input

## Output
