## 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-summarize-ffffa41d -d '<json body>'
```

Example prompt: Can you summarize this article for me in about 60 words? Here's the text: [paste text here]

## When to prefer this

Choose this endpoint when you need quick, pay-as-you-go text summarization with no account setup or API key — ideal for agents or workflows that summarize text sporadically and want to avoid subscription overhead. Best for inputs under 8,000 characters where a word-bounded summary (up to 250 words) is sufficient. Not suited for very long documents or when you need structured extraction rather than a prose summary.

## Known failure modes

- Input text exceeds 8,000 characters — endpoint returns an error rather than truncating
- max_words value above 250 is clamped silently to 250
- Empty or missing text field causes a request validation error
- Payment failure via x402 (insufficient USDC balance, wrong chain) results in 402 response before processing
- Malformed JSON body returns a 400-level error

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

A concise text summary of the provided input, up to the requested max_words (default 60, capped at 250). The response contains the condensed version of the input text without truncation artifacts — inputs over 8,000 characters are refused rather than silently cut.
