How this service works

Screenshot any URL. Extract structured data. Monitor for changes. Developer API with pay-per-call pricing — no API keys, no accounts.

Output

Returns a JSON object with a payment receipt and a results array. Each result includes the URL, a status field, and a data object containing: page title, markdown content, paragraphs, headings (with levels), links (with href and text), images, word count, and meta description. Batch requests return one result object per URL.

Example use cases

Competitive pricing research agent

“Extract the product names, prices, and descriptions from these 10 product pages and return them as structured JSON: [list of URLs] — use the schema 'product name, price, short description'.”

Article summarization pipeline

“Fetch the full markdown content from https://techcrunch.com/2024/01/15/some-article and give me the title, all headings, and the main body text so I can summarize it.”

Link audit for a webpage

“Scrape https://example.com and return every link on the page along with its anchor text — I need to audit where the site is linking to.”

Technical details

Endpoint

GEThttps://webcap.shoutsid.fyi/v1/x402/extract?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need structured extraction (links, headings, markdown, metadata) from one or a batch of up to 50 pages in a single payment, especially when you want a schema-driven JSON output without managing API keys or accounts. Prefer it over generic scraping tools when you need pay-per-call economics, browser-rendered content with optional stealth proxy, or natural-language schema definition for field extraction.

Side effects

URL unreachable or returns non-200 status — result status will indicate failure
JavaScript-heavy SPA may not render fully without specifying waitFor selector or post-load actions
Rate-limited or bot-protected pages may return empty or incomplete content without proxy/stealth options
Batch exceeds 50 URLs — request will be rejected
CSS selector in waitFor never appears — times out after capped 10,000ms
Invalid URL format causes parsing error
maxContentWords set too low may truncate important content
