# Arena Club

> Arena Club (Arenaclub.com, Inc.) is a technology-first trading-card and collectibles
> platform founded in 2022 by Brian Lee and Derek Jeter. It combines AI- and
> computer-vision-assisted card grading, an insured 24/7-surveilled physical vault, a
> digital "Showroom" for organizing vaulted cards, and an online marketplace for buying,
> selling and trading slabbed sports and trading-card-game cards. Members submit cards
> for grading and vaulting, transact in the marketplace, open digital packs, and can
> retrieve physical cards from the vault on demand.

## API status

Arena Club publishes **no public developer program**. As of 2026-08-06 there is no
developer portal, no API reference, no OpenAPI/AsyncAPI/GraphQL contract, no MCP server,
no A2A Agent Card, no `llms.txt`, and no `/.well-known/*` document on any Arena Club host.
An application backend exists at `api.arenaclub.com` (an Express service behind Cloudflare)
that serves the Arena Club web and mobile clients, but it is undocumented, unversioned in
public, and not offered for third-party integration. Nothing in this profile describes a
callable public API, because none is published.
