How this service works
Webpage Fields with Source Quotes: Read one public static HTTPS page and extract up to three named fields from its first 3,000 text characters using local AI. Each non-null value must occur in an exact source quote. No JavaScript rendering; missing or unsupported values return null. 0.01 USDC includes up to 3 fields from one webpage.
Output
A JSON object mapping each requested field name to its extracted value (or null if not found or not supported), along with a verbatim source quote from the page text confirming each non-null value. Results are based on the first 3,000 text characters of the fetched page, with no JavaScript rendering.
Example use cases
Competitor contact info lookup
“Go to https://www.acmecorp.com/contact and pull out the fields 'phone_number', 'email', and 'address' — I need the exact text from the page where each value appears.”
Article metadata extraction
“Fetch https://www.techblog.io/posts/ai-trends-2025 and extract 'author', 'publish_date', and 'title' from the page, along with the source quote proving each value.”
Product detail scraping
“Read https://shop.example.com/products/blue-widget and extract 'price', 'sku', and 'availability' — give me the snippet of page text where each value was found.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-webpage-field-extraction?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pull a small number of specific named fields from a known static public webpage and require a verifiable source quote for each extracted value. It is ideal for lightweight, citation-backed extraction tasks where JavaScript rendering is not needed and cost must be kept low ($0.01 per call). Prefer alternatives if you need to scrape dynamic/JS-heavy pages, extract more than 3 fields at once, or process large amounts of page text beyond 3,000 characters.
Side effects
- URL requires JavaScript rendering — returns null for all fields since only static HTML is parsed
- Page returns non-200 HTTP status — extraction fails with an error
- Field value does not appear in the first 3,000 characters — returns null for that field
- HTTPS not available or URL is not public — request rejected
- Requested more than 3 fields — input validation error
- Field name exceeds 40 characters — input validation error
