Tools: get_collection_stats get_card verify_nonce get_leaderboard get_pool get_recent_activity get_project_info get_mining_guide find_nonce
get_collection_stats | Live 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. params: none |
get_card | Full 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. params: tokenId* |
verify_nonce | Recompute the proof-of-work for a (miner, nonce) pair exactly as the contract does: work = keccak256(chainId ‖ contract ‖ miner ‖ nonce). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it would be accepted on-chain. params: miner*, nonce* |
get_leaderboard | On-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets. params: limit |
get_pool | Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards. params: none |
get_recent_activity | Recent on-chain activity (mints / pack opens) from the latest blocks. params: limit |
get_project_info | What Spirit Cards is: the game, the five-node loop (mine → merge → battle → stake → 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. params: none |
get_mining_guide | Step-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. params: none |
find_nonce | Grind a proof-of-work nonce for a miner address so it can mint immediately: work = keccak256(chainId ‖ core ‖ miner ‖ 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 — retry or lower maxAttempts. params: miner*, maxAttempts |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
