CORS
CORS (Cross-Origin Resource Sharing) is a browser security mechanism, defined by the WHATWG Fetch standard, that uses HTTP headers to let a server declare which other origins (domain, protocol, or port) are allowed to read its responses. It governs how web applications and single-page apps make cross-origin API requests, relaxing the browser’s same-origin policy in a controlled, server-declared way.
Also known as Cross-Origin Resource Sharing.
Providers that carry Cross-Origin Resource Sharing (CORS) 0
No provider in the catalog carries this standard as a tag yet. That is a statement about the catalog's tagging, not about adoption: a provider that implements Cross-Origin Resource Sharing (CORS) and says so in its APIs.json profile appears here on the next build. Add or correct a listing.
Reading
Read from the API Evangelist standards directory. Provider links come from the catalog's own identity tags and are rebuilt nightly. If this page is wrong about a standard or a provider, say so.
