NIP-98

HTTP authentication

NIP-98 lets a Nostr key sign HTTP requests. A website or upload service can check that signature to know which Nostr user is making the request, without needing a normal username and password.

This is useful for actions like uploading media or calling an API as your Nostr identity. It is like showing a signed permission slip instead of creating a separate account for every service.
