Dropbox vs The Null Pointer

Dropbox is a cloud file-storage and sync platform, and its API lets apps read, write, and share files and folders in a user's Dropbox account. A live POST against the real gateway, api.dropboxapi.com/2/users/get_current_account, returned a 400 without a token, reconfirming OAuth 2.0 auth over HTTPS, and a follow-up OPTIONS preflight echoed the request Origin in Access-Control-Allow-Origin, resolving cors from unknown to yes. The free Basic plan includes 2GB of storage, with paid Plus, Professional, and Business tiers raising the cap and adding team features.

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).
