## 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 text-summarizer-api-llama-3-1-8b-038ca10d -d '<json body>'
```

Example prompt: Can you summarize the following article into no more than 80 words? [paste article text here]

## When to prefer this

Choose this endpoint when you need a quick, faithful extractive-style summary of a text document with a controlled word budget, especially in agentic pipelines that need pay-per-call pricing without subscription overhead. Prefer it over general chat completions when summarization is the specific task and you want a purpose-built prompt rather than crafting your own. Not ideal for structured data extraction or multi-document synthesis.

## Known failure modes

- Input text too long for model context window — may truncate or error
- max_words not respected precisely — model may overshoot by a few words
- Vague or incoherent input text may produce a low-quality or incomplete summary
- Payment failure via x402 protocol returns 402 status before processing
- Empty or missing body field returns a validation error

## How this service works
