How this service works
AI Web Extractor (structured) — scrape a url into the exact JSON you ask for. POST {url, instruction}; a fast model reads the page and returns structured data per your instruction (prices, contacts, listings, specs, tables). Web scraping to structured JSON for agents. x402-native.
Output
A structured JSON object shaped according to the natural-language instruction provided. The response contains the extracted fields (e.g. prices, names, contacts, specs, table rows) parsed directly from the live page content at the given URL. The exact schema of the returned JSON mirrors what was requested in the instruction.
Example use cases
E-commerce price monitoring
“Scrape https://www.bestbuy.com/site/apple-macbook-pro and extract the product name, current price, any sale price, and availability status as structured JSON.”
Lead generation from directory
“Go to https://www.yelp.com/search?find_desc=plumbers&find_loc=Austin+TX and extract the business name, phone number, address, and star rating for each listing on the page as structured JSON.”
Job listing data extraction
“Pull all the job titles, locations, departments, and application links from https://careers.stripe.com/jobs and return them as structured JSON.”
Technical details
Endpoint
POSThttps://extract.vevang.com/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need web page content returned as structured, queryable JSON rather than raw markdown or HTML. It is ideal when you have a specific schema in mind (prices, contacts, listings, specs) and want an AI model to do the field mapping for you. Prefer this over the sibling markdown endpoint when downstream processing requires structured data rather than free-form text. Best for one-off extractions from public pages where you can describe the desired output in plain language.
Side effects
- URL is behind a login or paywall — extraction fails or returns incomplete data
- Page uses heavy JavaScript rendering that prevents content from being read
- Instruction is too vague or ambiguous — returned JSON may be incomplete or misaligned
- URL is malformed or unreachable — HTTP error or timeout returned
- Page structure changes break expected extraction patterns
- Rate limiting or bot protection on the target site blocks the fetch
- x402 payment fails — request not processed
