Tool list from our last check. Connect live to refresh it.

certified_draw

Run a TrueSpin certified draw on NameWheel: the winner is sealed by NameWheel's server before it is revealed, randomness from this connection is added, and the result is published on a permanent public proof page (namewheel.org/v/CODE) that anyone can check, with a button that recomputes the draw. Use it when the result must be provable to other people: a class prize, a team decision, a draw announced to a group. IMPORTANT: the title, every entry and the winner become public on the proof page, so only use names the person is happy to publish, and tell them so. Needs a connected NameWheel account (free). To draw against a list locked earlier with freeze_list, pass frozen_code instead of entries.

titlestring, required

The draw's public title, such as 'Year 9 reading prize' or 'Who presents first'.

entriesarray

The names or options, one per item, exactly as the person gave them. Repeating a name gives it another slot (another chance), as on the NameWheel website.

entropystring

Optional words or a number from the person, mixed into the draw's randomness.

frozen_codestring

Code or link of a list frozen earlier with freeze_list (namewheel.org/f/CODE). The draw uses exactly that list.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

check_plan

Say what this NameWheel connection can do: without an account (spins, teams, wheel links, checking draws) or with a connected account (certified draws, frozen lists, the account's draws), and how many certified draws are left today. Use it when the person asks about limits, their account, or why a request was refused.

read-only

No arguments.

freeze_list

Lock a list of entries in public before a draw, at namewheel.org/f/CODE, with a fingerprint and the exact time. Nobody can add or remove a name after that, and when certified_draw later uses this list (frozen_code), the frozen page links to the result. Use it when entries close before the draw happens. The title and every entry are public. Needs a connected NameWheel account (free).

Argument	Type	Description
title*	string	The list's public title.
entries*	array	The names or options, one per item, exactly as the person gave them. Repeating a name gives it another slot (another chance), as on the NameWheel website.

make_teams

Split a list of names into random teams or groups of even size, and show them as cards in the chat. Use it for class groups, project teams, game sides, rotations. Give either how many teams or how many people per team. Works without an account.

read-only

Argument	Type	Description
teams	integer	How many teams. Default 2 when team_size is not given.
title	string	A short title for the wheel, such as 'Period 3 cold call' or 'Who presents first'.
entries*	array	The names or options, one per item, exactly as the person gave them. Repeating a name gives it another slot (another chance), as on the NameWheel website.
team_size	integer	How many people per team, instead of a number of teams.
team_names	array	Names for the teams, in order. Default Team 1, Team 2...

open_wheel_link

Make a namewheel.org link that opens the full NameWheel wheel with these names already loaded, for spinning on a projector, a stream or a shared screen with sound, modes and themes. Works without an account. Commas inside a name become spaces in the link.

read-only

Argument	Type	Description
title	string	A short title for the wheel, such as 'Period 3 cold call' or 'Who presents first'.
entries*	array	The names or options, one per item, exactly as the person gave them. Repeating a name gives it another slot (another chance), as on the NameWheel website.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [

    }
  },
  "additionalProperties": false
}

spin_wheel

Pick one or more winners at random from a list of names or options, and show the wheel spinning to the result in the chat. Use it whenever the person wants something chosen at random: a student to answer, who goes first, where to eat, a raffle winner among friends. Works without an account. The pick is fair (a cryptographic random number generator), but it is not a certified record; when other people need to be able to check the result later, use certified_draw instead.

read-only

Argument	Type	Description
title	string	A short title for the wheel, such as 'Period 3 cold call' or 'Who presents first'.
entries*	array	The names or options, one per item, exactly as the person gave them. Repeating a name gives it another slot (another chance), as on the NameWheel website.
winners	integer	How many winners to pick. Default 1.
allow_repeat_winners	boolean	With more than one winner, may the same entry win twice? Default false: each winner leaves the wheel.

  },
  "additionalProperties": false
}

verify_draw

Check whether a NameWheel certified draw is genuine, from its code or its namewheel.org/v/ link: recomputes the winner from the published secret, the added randomness and the entries, checks the commitment made before the spin, and checks NameWheel's Ed25519 signature on the record. Also says how many draws the host ran on this exact list. Use it when someone asks whether a draw or a giveaway result was real. Works without an account.

read-only

Argument	Type	Description
code*	string	The draw code (8 letters and digits) or its link, such as namewheel.org/v/DG5J6VD7.
