OpenAPI Specification

openapi: 3.2.0
info:
  title: Web Toolbox CORS Proxy API
  description: A CORS proxy and web-utilities API. Fetch any URL with permissive CORS headers (bypass 'blocked by CORS policy' errors), extract link preview metadata (Open Graph / Twitter cards), grab favicons, and inspect response headers and redirect chains — all from one endpoint set.
