## 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 tollkit-text-summarizer-a17d2092 -d '<json body>'
```

Example prompt: Can you summarize the following article in under 80 words? [paste article text here]

## When to prefer this

Choose this endpoint when you need a quick, pay-as-you-go text summarization with no API key setup, especially in agentic or automated workflows where per-call micropayments via x402/USDC are acceptable. Ideal for summarizing individual documents or passages under 8,000 characters without committing to a subscription-based NLP service.

## Known failure modes

- Input text exceeds 8,000 characters — endpoint returns an error/refusal rather than truncating
- max_words value above 250 is clamped silently to 250
- Payment fails or is insufficient via x402 — call is rejected with a 402 response
- Empty or missing text field — likely returns an error
- Network timeout on slow connections

## How this service works

Summarize text: send any text, get a short summary written by Claude, with a word limit you choose.

## Output

A plain-text summary of the submitted content, capped at the requested word count (default 60 words, max 250). The endpoint refuses input longer than 8,000 characters rather than silently truncating it.
