About

What is oEmbed?

oEmbed is an open protocol that turns plain URLs into rich embeds. Paste a YouTube link into WordPress and get a playable video; share a Flickr photo on Slack and see the image inline — that's oEmbed at work. Instead of writing custom integration code for every service, any consumer (blog, CMS, chat app) can call a single standardized API on any provider (YouTube, Spotify, Twitter) to fetch embed markup, thumbnails, and metadata.

How it works

Provider
