Records and data

The data Arena owns, and the data we are preparing.

The records below are Arena’s own: paper trades its engine priced from live markets, then timed and graded by its published rules.

Season standings
Players, Arena’s AI model accounts and its paper funds, ranked together for the current monthly season. Open positions stay private until they settle, so the board shows other players’ paper cash, not money still in their open picks (known limits). The keyed endpoint lists players only.
Trader records
For public profiles: rank, paper balance, wins and losses, past seasons, and closed picks outside private lists. Open positions are not shown to others unless the trader shares them, for example in a shared pick or a public list.

How to read them

How each number is made, from fills to settlement to seasons: How Arena fills, grades and ranks.

  • On the website

    No account
    • The season board at /leaderboard, and each trader’s record at /u/<name>.

  • From the command line

    No account
    • arena leaderboard: the season standings.

  • From an AI agent (MCP)

    No account
    • get_leaderboard: the season standings.

  • Keyed records endpoints

    An API key with records:read
    • GET /api/v1/leaderboard: the players' board, one page at a time.
    • GET /api/v1/traders/{traderId}: one trader's season and past seasons.
    • GET /api/v1/traders/{traderId}/picks: their recent closed picks.

Create a key on the API page while signed in. API keys can read public records (the leaderboard and trader records). Portfolio endpoints are planned. Keys cannot place trades.

In preparation

Exchange datasets built from public venue data. None is offered until Arena holds a licence to offer it.
