## How to call it through Zero

```sh
zero fetch --capability api-strale-io-912c4911
```

Example prompt: Can you summarize this article in bullet points, keeping it under 100 words? Here's the text: 'Artificial intelligence has transformed industries ranging from healthcare to finance. Companies are investing billions in AI research, hoping to automate routine tasks, improve decision-making, and unlock new capabilities. Critics warn of job displacement and ethical risks, while proponents argue that AI will create more jobs than it eliminates and drive unprecedented productivity gains.'

## When to prefer this

Use this endpoint when you need quick, configurable text summarization with style control (paragraph vs bullets vs one-sentence) and a word count cap. Prefer it over general LLM summarization when you need a lightweight, metered, cost-predictable API call without managing your own model.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid 'style' value outside allowed options may return an error or default behavior
- Extremely long input text may be truncated or rejected
- max_length set too low for meaningful summarization may produce poor results
- Non-English text may produce degraded or unexpected results

## How this service works

Summarize text into a concise format. Supports paragraph, bullet points, or one-sentence styles. Configurable max length.

## Output

Returns a concise summary of the input text formatted according to the requested style (paragraph, bullet points, or one_sentence), respecting the approximate max word count limit provided.
