## 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 losbeto-summarize-13a72b97 -d '<json body>'
```

Example prompt: Summarize this quarterly earnings filing in 3 sentences, keeping all financial figures exact — here's the text: [paste 2,000-word filing].

## When to prefer this

Choose this endpoint when an agent needs to compress a document, email thread, page, or financial filing to save context window space before passing it to another reasoning step — especially when exact numbers must be preserved. It is NOT a free-form writing or generation tool; use /llm for that. Best for deterministic, factual compression tasks rather than creative or analytical generation.

## Known failure modes

- Text shorter than 40 or longer than 6000 characters returns a validation error
- sentences value outside 1–8 range is rejected
- Payment not received or USDC transaction fails — 402 response, call not executed
- Unsupported or malformed language code may produce unexpected output language
- Empty or missing 'text' field returns a 400 bad request
