How this service works

Output

Example use cases

Quick article digest for research

“Summarize this news article for me in bullet points so I can get the key takeaways fast: https://www.reuters.com/world/europe/some-long-article”

Invoice or document understanding

“I just got this invoice text and need a short summary of it — what's the total amount, who it's from, and when it's due: 'Invoice INV-2026-0042, issued by Acme GmbH, total 1,250.00 EUR, due 2026-10-31.'”

Technical details

Endpoint

POSThttps://api.sitecheck-api.workers.dev/api/summarize?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a quick LLM-powered summary of a web page or a block of text, especially when you want structured output (summary + key points), multilingual support, or adjustable length (short/medium/bullets). Prefer this over generic LLM calls when you want a single pay-per-call API that fetches and summarizes a URL in one step without managing your own scraping and prompting pipeline.

Side effects

URL is unreachable or returns a non-200 status — endpoint may return an error or empty summary
Text exceeds 12,000 character limit — input may be truncated or rejected
Unsupported or misspelled language code — summary may default to English or return an error
Empty input (no URL and no text provided) — returns validation error
URL points to a PDF or non-HTML resource not supported by the reader — may fail to extract content
