Gyazo vs The Null Pointer

Gyazo is a screenshot and screen-capture sharing service whose API lets apps upload images and GIFs and fetch a user's capture history. A live GET against the real gateway, api.gyazo.com/api/images, returned a 401 without a token, reconfirming API-key auth over HTTPS, and a follow-up OPTIONS preflight returned Access-Control-Allow-Origin: *, resolving cors from unknown to yes. The free tier covers everyday screenshot sharing, while a paid Gyazo Pro plan adds unlimited uploads, higher-res captures, and privacy controls.

The Null Pointer (0x0.st) is a minimalist, no-account temporary file host and URL shortener: a plain POST with a file returns a bare URL as the entire response body, with retention scaled by file size. A live OPTIONS preflight with an Origin header against the real host, 0x0.st, returned a 200 with no Access-Control-Allow-Origin header, resolving cors from unknown to no; no auth is required for uploads, and HTTPS was reconfirmed. It's a single free, ad-free service with no paid tier, retaining files from 30 days up to 1 year depending on size (max 512MiB).
