Zovo Fair Draw

Use this when the user wants a fair random pick of winners from a group: a giveaway, door prize, raffle without tickets, classroom or team pick. Publishes a draw page with a public link where entrants add their names (or only the organizer adds them), and returns a private organizer link. Optionally adds a first list of names. Up to 500 entries, 1 to 20 winners, up to 10 backups. For free draws only: set free_entry to true to confirm nobody pays to enter; it does not handle money. Does not draw yet; use draw_winners for that.

Use this when the organizer wants to add entrant names to a draw made with create_prize_draw, before the winners are drawn. Takes the private organizer link and a list of up to 100 names per call (send more in further calls). Duplicate names (ignoring case) are skipped and reported. Does not draw; does not remove names.

Use this when the organizer is ready to pick the winners of a draw made with create_prize_draw. Takes the private organizer link. Closes entries, picks the winners and backups with the published method, and reveals the seed on the public page so anyone can verify. The result is final: running it again returns the same winners. Needs at least one entry. Does not add or remove names and does not redraw.

Use this when the user wants the state of a draw made with create_prize_draw: number of entries, the names, the commitment, and after the draw the winners, backups and proof values. Takes the private organizer link. Does not change the draw.
