Gyazo API
Overview
Gyazo is a screenshot hosting API that accepts an image upload and returns a permanent shareable URL with associated metadata like capture time and application info. It specializes in screen captures, making it easy to share visual content via a short link without managing your own image storage. Developers use it to automate screenshot archiving, build visual feedback tools, or create screenshot-sharing bots.
Beginner Tip
Get a free API access token from gyazo.com/oauth/applications by registering an app with any redirect URI. Uploads require multipart/form-data with the image sent as the "imagedata" field — test with a PNG screenshot first.
