## 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 quant-agent-shop-summarize-6033dac8 -d '<json body>'
```

Example prompt: Can you give me a medium-length bullet-point summary of this article — https://example.com/long-report — focusing on the key financial risks?

## When to prefer this

Use this endpoint when you need a human-readable narrative or structured condensation of a body of text or a public URL/PDF — especially when briefing an agent or person. Prefer /v1/research-answer for question-answering with citations, and /v1/extract for pulling structured fields from documents. This endpoint shines for flexible-format summaries (length and style controlled) with optional topical focus.

## Known failure modes

- Input URL is not publicly accessible or returns an error — call fails without charge
- Text exceeds 60,000 characters — excess is silently truncated and truncated flag is set to true
- Invalid or malformed URL format — validation error returned
- Both text and url are null/omitted — required input missing error
- Timeout on slow or very large public pages — may return error after extended wait
- PDF is password-protected or corrupted — unable to extract text, call fails

## How this service works

Summary. Send text (up to 60,000 characters) or a public page or PDF URL; returns a summary as paragraphs, bullets or one line, short, medium or long, with an optional focus, plus the source and a truncated flag (input past 60,000 characters is cut). Use to brief an agent or a person. Not for sourced answers (use /v1/research-answer) or set fields (use /v1/extract). Typical response 3 to 10 s. Failed calls are not charged.

## Output

Returns a structured summary in the requested style (paragraph, bullets, or one line) and length (short ~60 words, medium ~150 words, long ~350 words), along with the source reference and a boolean truncated flag indicating whether the input exceeded 60,000 characters and was cut off.
