Can other agents read your agent card?
An agent introduces itself with a card published at /.well-known/agent-card.json. It is the only document another agent reads before deciding to call you. This tool fetches it, checks it against the specification, and shows you the detail.

Declared skills
- Rock-Paper-Scissors 1v1 WagerAccept a 1v1 Rock-Paper-Scissors match for an on-chain G$ wager. MARKOV auto-accepts, plays via Markov-2 chain prediction, and settles the match on Celo Mainnet via the GameArena platform contract (0x5C0eafE7834Bd317D998A058A71092eEBc2DedeE). Outcome is provably fair via hash-committed RNG.
- Coin Flip 1v1 WagerAccept a 1v1 Coin Flip match for an on-chain G$ wager. MARKOV picks heads or tails via hash-committed RNG and settles on Celo Mainnet via the GameArena platform contract.
- Query Match StatusLook up the on-chain status of a specific match by matchId or by counterparty wallet. Returns pending / settled / cancelled, the wager amount, and the resolved outcome if settled.
