How this service works

Extract prices, lists, tables and events from public web pages and get notified when they change. RSS, ICS, signed webhooks, MCP. Static HTML only.

Output

Returns a JSON object containing the extracted data under a 'data' key, the extraction mode used, the final resolved URL, a fetch timestamp, and metadata including match count and whether results were truncated. For 'page' mode, includes title, headings, word count, content hash, canonical URL, and description. For other modes, data is mode-specific (price string, array of list items, array of table rows, etc.).

Example use cases

Track competitor product pricing

“Pull the price from https://shop.competitor.com/item/widgets using the CSS selector '.product-price' in price mode — I want to know what they're charging right now.”

Extract event listings from a public calendar

“Grab the list of upcoming events from https://cityevents.org/calendar using the CSS selector '.event-item' in events mode and give me the results as an ICS calendar file.”

Scrape a comparison table from a webpage

“Extract the first table from https://broadbandcompare.com/plans — use table mode with tableIndex 0 — I need all the plan names and prices in JSON format.”

When to prefer

Choose this endpoint when you need to extract specific structured data from a known static public web page — particularly prices, tables, event lists, or CSS-targeted text — without needing JavaScript rendering. It is ideal for one-shot data pulls from product pages, public directories, or news sites. Prefer alternatives if the target page requires JavaScript (SPA/React sites), requires authentication, or if you need full-site crawling rather than single-page extraction.

Side effects

URL is not publicly accessible or uses a non-standard port — returns error
Page requires JavaScript rendering (only static HTML is supported) — returns empty or incomplete data
CSS selector is malformed or exceeds 300 characters — returns validation error
Selected element or table index not found on page — returns empty match with matched:0
URL resolves to a private IP or non-public DNS — blocked for security
fields parameter exceeds 20 fields in list mode — returns validation error
Requested URL returns non-HTML content — extraction may fail or return unexpected results
