get_collection_statsLive collection statistics for Spirit Cards: total minted, max supply, current mint price (ETH), difficulty (requiredBits/baseBits), cooldown, merge fee, burned/forged counters, paused flag, chainId and contract.
get_cardFull profile of a Spirit Cards token by id: species, element, rarity tier, HP/ATK/DEF, and the deterministic on-chain seed. Works for any minted token id.
verify_nonceRecompute the proof-of-work for a (miner, nonce) pair exactly as the contract does: work = keccak256(chainId â contract â miner â nonce). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it would be accepted on-chain.
get_leaderboardOn-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets.
get_poolStaking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards.
get_recent_activityRecent on-chain activity (mints / pack opens) from the latest blocks.
get_project_infoWhat Spirit Cards is: the game, the five-node loop (mine â merge â battle â stake â points), the chain (Robinhood Chain, CORE contract, explorer, ETH gas), official links, the collection (species / rarity tiers / battle elements) and the key economy (max supply, price step, fee split). Call get_mining_guide to start mining.
get_mining_guideStep-by-step guide to mine a Spirit Card: the exact proof-of-work rule, the live difficulty / price / cooldown / chip discount, where to get a miner (browser at /mine, public CLI), the exact contract call, and how to get a valid nonce with the find_nonce tool.
find_nonceGrind a proof-of-work nonce for a miner address so it can mint immediately: work = keccak256(chainId â core â miner â nonce), using the live requiredBits threshold. Returns the first nonce whose work has at least requiredBits leading zero bits, within a ~20 s wall-clock cap. If the difficulty is high it may return found:false â retry or lower maxAttempts.
