Open Agora polling API

AgoraPI (Agora Polling Interface) offers a set of services related to polling and voting. These services are offered through a public API, in other word a web-service which may be queried by other computer programs or servers. AgoraPI provides simple access to complex voting methods (like Condorcet method, instant-runoff or majority judgement).

We recommend using ranked voting systems, however AgoraPI also allows to create usual polls (majority or approbation polling).

Features of AgoraPI

  • Create a Poll

    A single request to AgoraPI sets the text and the choices of a poll.

  • Manage a Poll

    During the whole poll lifetime it is possible to add or remove choices while preserving existing votes.

  • Manage Voters

    Each voter gets a unique identifier. This identifier can be used to cast a vote or to modify a vote later on.

  • View Results

    AgoraPI produces a graphical result for approbation (majority) and Condorcet polls. Soon, AgoraPI will be enriched with other kinds of results (instant runoff or majority judgement).

    Results are available in real-time.

  • Your Rules

    It is our API, but it is governed by your rules. You are free to manage your users, to allow or forbid multiple choices, to set up a veto system (the possibility to let a user remove a choice completely) or to let choices be reformulated.

    The only limit is your creativity.

(**): A query corresponds, for instance, to the creation of a poll with its choices, to the addition of choices, to the vote of an user, or to the computation of the latest results. Only successful queries are taken into account. Furthermore, accessing the graphical charts does not count as a query.
