## Tools (as reported by the server, not verified)

- `list\_haplogroups`: Search or list paternal haplogroups by fuzzy name and/or parent, with stable ordering for full pagination \(order=name recommended\). 搜索/列出父系单倍群：按名称模糊匹配、按父节点筛选，稳定排序可完整枚举。
- `get\_haplogroup`: Get a single haplogroup by name / hid / SNP. 按名称/hid/SNP 获取单个单倍群详情。
- `get\_haplogroup\_mutations`: List a haplogroup defining \(equivalent\) mutations \(paternal / Y tree only\). 获取某单倍群的等价突变（defining SNPs）列表（仅父系 Y 树）。
- `get\_haplogroup\_lineage`: Get the lineage chain from a haplogroup up to ROOT. Use limit to fetch only the most recent N levels \(e.g. limit=2 for the node + its parent\). 获取某单倍群上溯到 ROOT 的谱系链；可用 limit 只取最近 N 级（如 limit=2 即该节点与其直接父级）。
- `children\_haplogroups`: Get the direct children of a haplogroup \(for level-by-level traversal\). Use limit for the N largest subclades only. 获取直接子节点（逐层遍历）；可用 limit 只看最大的 N 个分支。
- `resolve\_snp`: Resolve a SNP name to its haplogroup and return equivalent names \(merged-name variants supported\). 将 SNP 名解析到所属单倍群并返回等价名。
- `resolve\_snps`: Batch-resolve up to 200 SNP names to their haplogroups \(for reading a whole Y-SNP panel\). 批量解析多个 SNP 名到所属单倍群（≤200/次）。
- `subtree\_haplogroups`: Get a haplogroup subtree. Defaults to 6 levels \(matches the site\); small branches \(root endcounts\<=600\) fully expand; max\_depth overrides. Truncated boundary nodes carry has\_children. 取子树：默认 6 层，小支\(endcounts\<=600\)全展开，可传 max\_depth；截断边界带 has\_children。
- `get\_api\_info`: Get service meta: summary, auth, dataset size \(haplogroups / mutation records\), and the tool list. 获取本服务元信息：简介、鉴权、数据集规模、工具清单。
