How this service works
OPX builds machine-facing infrastructure and paid tools for x402 commerce. Its current live tool helps agents choose between tested x402 web-search providers before spending using recent paid performance evidence.
Output
Returns a JSON object containing a 'data' map of the requested field names to their extracted values (or null if missing), the final resolved URL after any redirects, the original source URL, a unique request ID for tracing, and a 'missingFields' array listing any fields that could not be extracted from the page.
Example use cases
Product price monitoring for e-commerce
“Extract the product title, current price, and availability status from https://shop.example.com/item/12345 — make price a required field so we only settle if it comes back.”
News article metadata extraction
“Pull the headline, author name, and publication date from this news article at https://news.example.com/article/breaking-story and return them as structured JSON fields.”
Business info scraping for lead enrichment
“From the company page at https://acmecorp.com/about, extract the company name as a string, founding year as a number, and whether they list a contact email as a boolean — I need all three as required fields.”
Technical details
Endpoint
POSThttps://opx-status.dev/api/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract specific named fields from a known public URL and want structured, validated JSON back without writing custom scraping logic. It is especially well-suited for agentic workflows where you want pay-on-success semantics — payment only settles when required fields are actually delivered. Prefer it over generic scraping tools when you need field-level type validation (string, number, boolean) and a clean missing-field report.
Side effects
- Required field not found on page — extraction fails and payment does not settle
- URL points to a private or internal address — rejected before retrieval
- Webpage is behind authentication or a JavaScript-heavy SPA — extraction may return nulls
- Field name uses reserved keyword (__proto__, constructor, prototype) — request rejected with validation error
- URL is malformed or exceeds 4096 characters — rejected at input validation
- Page returns non-200 HTTP status — extraction fails with no data returned
