What Arcade is for

Games questions with real data behind them: a chess player's actual ratings and last games, today's puzzle, who is top of the leaderboard, whether a PC game is on sale and the cheapest it has ever been, which free-to-play games are popular, the world record for a speedrun and who holds it, a Pokémon's stats and evolutions, and a batch of trivia questions to run a quiz — from the sites that publish open APIs.

What it does

Chess: profiles, per-mode ratings and records for any Chess.com or Lichess user; recent games with opponent, result, opening and link; the daily puzzle from either site with solution; leaderboards by time control. Deals: current prices and discounts across ~25 PC stores by title, price cap, discount or store, with Metacritic and Steam ratings; a game's cheapest price now and ever with every store's offer. Free-to-play PC and browser games by genre. Speedrun world records per full-game category with runners, times, dates and videos. Pokémon data with base stats, abilities, Pokédex entry, evolution chain and artwork. Trivia by category, difficulty and type with shuffled options and answers.

What it is not

Arcade has no console or mobile store prices (CheapShark covers PC), no game reviews or news, and no play — it does not make moves or run games. Chess ratings are site ratings, not FIDE. Board Game Geek now requires registration and is not included.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Arcade — Privacy Policy

Effective 23 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Arcade is. Arcade is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for games information: chess players, games, puzzles and leaderboards; PC game deals and prices; free-to-play games; speedrun records; Pokémon data; trivia questions. You interact with your assistant; the assistant sends us only the username, game title or other lookup term needed.

What we receive. The arguments of each tool call (a chess username — possibly your own — a game title, a Pokémon name, quiz filters), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Lookups are forwarded, not stored. A username or title is passed to the relevant public API and the answer is returned to your assistant. Chess profiles and games are the public data those platforms already publish about the account; we do not log which accounts are looked up or link lookups to you. Nothing you send is stored, logged in request bodies, profiled or used to train anything. Successful upstream answers are cached in memory for 10 minutes to 7 days, keyed by the query, to reduce load on the sources.

What we do not receive or store. We do not receive your conversation with the assistant, your name, contacts, accounts or credentials for any service, and we cannot act on any account (no moves, no purchases). Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. Chess.com (public API), Lichess, CheapShark, FreeToGame, speedrun.com, PokéAPI and Open Trivia Database. Each receives the query and our server's IP address, never yours. Hosting: Vercel (United States regions).

Legal bases and your rights. For users in California, the EU/UK and elsewhere, our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Arcade is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Arcade — Terms of Service

Effective 23 September 2026. These terms govern use of the Arcade connector ("the Service") operated by Unify Dynamics LLC ("we", "us").
