How this service works
Schema extraction - send a URL and the fields you want (for example price, title) and get a JSON object back
Output
A JSON object whose keys are the field names you specified and whose values are the corresponding data found on the page. If a field cannot be found, it may be null or omitted. The response reflects the content of the live page at the time of the request.
Example use cases
Competitor price monitoring
“Pull the current price and product name from https://shop.competitor.com/item/456 — I want those two fields back as JSON.”
News article metadata extraction
“Go to this article URL https://techcrunch.com/2024/05/01/some-story and extract the title, author, and publication date for me.”
Job listing detail scraping
“Fetch https://jobs.example.com/listing/789 and extract the job title, salary range, location, and required experience from the page as structured JSON.”
Technical details
Endpoint
POSThttps://x240.jvnclk88.workers.dev/extract?utm_source=zero.xyzWhen to prefer
Use this endpoint when you know exactly which named fields you want from a page and need them as structured JSON, rather than raw text or all metadata. It is ideal for targeted data extraction (e.g. price, title, author) without post-processing. Prefer it over the product-page or metadata endpoints when you need custom field names beyond their fixed schemas, and over the batch scrape endpoint when you need clean, typed values for specific fields from a single URL.
Side effects
- URL is not publicly accessible or returns a non-200 status — extraction fails with an error
- Page content is JavaScript-rendered and the relevant fields are not present in the initial HTML — fields may be null
- More than 20 fields requested — request rejected
- Field names are too ambiguous to match page content — returns null values for unmatched fields
- URL is malformed or not http/https — request rejected with validation error
