API Reference
Full reference for the Serpex Search, Extract and Usage endpoints.
Stealth mode will no longer be available from 1 November 2026. Search and Extract are unchanged.
The Serpex API has two core endpoints, search the web and extract page content, plus stealth mode for JavaScript-heavy pages and a free endpoint to check your credits and usage.
Search
GET or POST /api/search: structured web-search results in JSON.
Extract
POST /api/crawl: clean page content as Markdown or HTML.
Usage
GET /api/usage: credit balance and request counts. Free.
Stealth Mode
Full-browser rendering for JavaScript-heavy pages.
Errors
Status codes, retry guidance, and what is never charged.
