{ "openapi": "3.1.0", "info": { "title": "Arena API", "version": "1.11.0", "summary": "Arena Predictions paper trading with an API key: read, and place paper orders with trade:write. Arena-owned data only.", "description": "Arena Predictions (arena-predictions.com) is a sandbox for paper trading prediction markets at live prices. Every endpoint here serves Arena's sandbox, where every trade is a paper trade (mode \"paper\"); routing to live trading is coming. Keys are read-only and reach Arena-owned data only: the key's own identity and account, the leaderboards and published trader records with their resets and settled picks. Keys are managed with the signed-in browser session, never with a key. No exchange ticker, market title, entry price or venue price appears in any keyed response; the owner's own portfolio carries the owner's own paper numbers (a resting order's limitCents, a position's costDollars and contracts). Balances carry over: every account starts with 100,000 paper dollars, and a reset (at most one every 30 days, shown on a public profile) starts a new run. 1.2.0: seasons removed (no season field anywhere), leaderboard windows and kinds, trader resets, GET /account. 1.3.0: accounts are private by default. A private trader answers private: true with every P&L and rank null (resets and busts 0) and an empty pick list; a public trader whose earlier trades are still hidden has numbersShown: false and no P&L or rank. The key owner reads their own picks (each with placedPrivate and shown) and their own eval rows (GET /me/eval) with portfolio:read. No key can make an account public. 1.4.0: keys are managed by a person's session, on the website or as a signed-in CLI's session token (arena keys), never by a key; keys rotate with a grace period; every keyed answer carries the plan and its counts (RateLimit-*, Arena-Quota-*, Arena-Plan) and GET /usage says where the account stands; a new scope, markets:read, reads instruments, games and quotes; GET /portfolio and /portfolio/trades read the owner's positions, orders and trades. Venue references and venue prices are served only while the venue-data switch is on (it ships off): until then the quotes routes answer 403 venue_data_off and nothing keyed names a ticker or a venue's price. 1.5.0: GET /eval, the public eval board (records:read), each row with 95% intervals clustered by game. 1.6.0: GET /traders/{traderId}/track-record, a trader's Ed25519-signed 90-day record exactly as Arena signed it (records:read; it names Kalshi series inside its signed bytes, so it is served only while the venue-data switch is on), and tiedWithAbove on each eval row (null while this row's or the row above's interval is unknown). 1.7.0: a key created with trade:write (only when asked for by name: the Settings checkbox, arena keys create --trade, or scopes in the body) places paper orders with POST /portfolio/orders and cancels them with DELETE /portfolio/orders/{orderId}, at Kalshi's paths. Market and limit orders, buys by instrument or ticker and sells of a whole position, each with an idempotencyKey: the same key again answers the stored order with replayed: true and places nothing. Hard trade limits are always enforced: per key 10 new orders a minute and 50 a day, and 20 sells and cancels a minute; per account, across every key and connected app, 20 new orders a minute, 100 a day, and 40 sells and cancels a minute. 1.8.0: GET /traders/{traderId}/track-record asks promote-record for audience=keyed and is served while the venue-data switch is off (records:read). That envelope has the same scores, signed with the same key, and names no Kalshi series ticker and no venue. Quotes still answer 403 venue_data_off until the switch is on. The CLI, the Python SDK and hosted MCP verify still read the public envelope, which names series. 1.9.0: POST /backtest (markets:read) forwards a paper replay of settled Kalshi game-winner markets to the backtest edge function. The JSON body is forwarded and the function's JSON is returned, with mode paper. GET and every other method answer 405 method_not_allowed and are not forwarded. 1.10.0: X-Arena-Org, an organization id, on GET /portfolio, GET /portfolio/trades, POST /portfolio/orders and DELETE /portfolio/orders/{orderId}. When the header is present those calls use that organization's paper sandbox. When it is absent they use the key owner's personal paper account. A value that is not an organization id is 400 invalid_request. An unknown organization is 404 organization_not_found and one this key cannot use is 403 organization_forbidden. The personal account is never the fallback, and the header does not select a Combine evaluation account. Paper only. 1.10.1: GET /organizations lists the organizations a personal API key belongs to. The call is forwarded to the organizations edge function with the caller's key, and the function's JSON is returned with mode paper. Each organization's id is what X-Arena-Org takes on the portfolio and paper-order routes. Any valid key, no particular scope. Paper only. 1.10.2: GET /portfolio and GET /portfolio/trades with X-Arena-Org return that organization's paper sandbox (cash, positions, resting orders and trades) and organization.slug. They do not return the personal account. 1.11.0: GET /history, GET /history/candles, GET /history/as_of and GET /history/export (markets:read) forward the query string to the Fly history service. The caller's key is checked here. The Fly server key stays on the server and is sent as x-arena-server-key to /srv/history*. The service's JSON is returned unchanged, and export may be CSV. While the venue-data switch is off these answer 403 venue_data_off and Fly is not called. A 400 or a non-auth 403 from the service keeps that status. A Fly 401 (the server key was refused) is 503, so a good caller key is not reported invalid. GET and HEAD only. Paper only.
