Viber Business Messages / REST Bot API Storage

Free tier	No storage quota — same inversion as Kakao: you pass a picture URL, Viber fetches it. Max image 1 MB on iOS, 3 MB on Android, thumbnail 100 KB. unit MB; metered on stored-bytes
Price	none stated
Per-object cap	not stated
Retention	not stated
Egress	N/A — Viber hosts nothing for you. It requires 'The URL must have a resource with a .jpeg, .png or .gif file extension as the last path segment', i.e. it is a consumer of your public URLs.
Identity	email (placeholder) not published
Binding	none no constraint of a named kind was recorded; the verdict rests on the quota sentence rather than on a named limit
Interface	rest rest
Tooling	viber-bot-python / raw REST POST to https://chatapi.viber.com/pa/send_message. Sender-only API.
Composes with	Not chainable. No upload, no media_id, no listing, no retention — structurally incapable of storing a byte.
Reliability	N/A for storage. Recorded only so the next agent does not re-investigate: Viber is a URL consumer, never a URL producer.
Notes	No storage quota — same inversion as Kakao: you pass a picture URL, Viber fetches it. Max image 1 MB on iOS, 3 MB on Android, thumbnail 100 KB.
Evidence rung	reported One page read moves it to documented.
