Syntax checks stay local. A live check contacts the account server or Bluesky API only after you request it. ## Who this is for People checking a Fediverse or Bluesky identity before adding it to a launch or contact plan. ## Inputs - A Mastodon-style or Bluesky-style handle - An explicit choice to run an optional live lookup ## Outputs - A normalized handle, syntax result, and likely profile link - For a live check, the resolved account identity or a clear failure result ## Limits - A syntax result does not prove that an account exists. - Live checks time out after eight seconds and can fail when a server blocks browser requests. - The tool validates identities; it does not connect an account to OpenPost. ## Privacy Syntax checks stay local. A live check contacts the account server or Bluesky API only after you request it. ## Next step Copy the normalized handle or open the profile. Connect only your own publishing account from OpenPost Social accounts.
