How this service works
Fetch a public web page and extract the fields you name into clean JSON (e.g. fields=name,price,currency,availability or company,ceo,founded). Missing values come back as null. Up to 20 fields.
Output
A JSON object containing the requested URL and a data map with each requested field name as a key and the extracted value (string or null) as the value. Fields not found on the page are returned as null.
Example use cases

Lead enrichment from company website
“Extract the company name, tagline, and contact_email from https://acmecorp.com so I can enrich this lead record before the sales call.”
News article metadata extraction
“From https://techcrunch.com/2024/06/01/some-article, extract the title, author, and published_date fields so I can log them to my content tracker.”
Technical details
Endpoint
GEThttps://138-197-15-135.sslip.io/v1/ai/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract specific named fields from a known public URL as structured JSON, especially in agentic pipelines that already support x402 micropayment flows. It is well-suited for one-off enrichment tasks (lead data, product details, article metadata) where you know exactly which fields you want rather than needing full-page Markdown or free-form summarization.
Side effects
- URL is not publicly accessible or behind a login wall — returns null values or error
- Field names not found on the page — returns null for those fields
- Invalid or malformed URL — request fails with an error
- Too many fields requested (max 20) — validation error
- Payment via x402/USDC fails — 402 Payment Required response before extraction occurs
- Rate limiting or bot protection on the target site — may return incomplete data
