如何批量获取小红书笔记评论

用 3 个接口：小红书笔记搜索 → 小红书笔记评论 → 小红书评论回复。下面的示例一共 14 次调用，合计 $0.28；失败的调用不收费。

按关键词搜出一批小红书笔记，取每篇笔记下的一级评论，再展开回复多的评论。最后得到一张评论表：正文、评论者、点赞数、回复数、发布时间。

第 1 步：小红书笔记搜索

按搜索词取一页笔记，sort 可以选最新或最热。每条的 id 是笔记编号，原样传给下一步；metrics.comments 是评论数，可以先挑评论多的。

cURLPythonTypeScript命令行

curl -G "https://api.dataxapi.com/v1/xiaohongshu/notes/search" \
  --data-urlencode "query=咖啡" \
  -H "Authorization: Bearer $DATAXAPI_API_KEY"

from dataxapi import DataXAPI

dx = DataXAPI()  # reads DATAXAPI_API_KEY
result = dx.xiaohongshu.notes.search(query="咖啡")
print(result["data"]["items"])

import { DataXAPI } from "@dataxapi/sdk";

const dx = new DataXAPI(); // reads DATAXAPI_API_KEY
const result = await dx.xiaohongshu.notes.search({ query: "咖啡" });
console.log(result.data.items);

dataxapi call xiaohongshu.notes.search 'query=咖啡'

第 2 步：小红书笔记评论

把笔记编号放进 id，取一页一级评论，按时间从新到旧。要下一页，就把 page.next_cursor 作为 cursor 再调一次。每条评论的 id、post_id 和回复数 metrics.comments，下一步用。

curl -G "https://api.dataxapi.com/v1/xiaohongshu/notes/comments/list" \
  --data-urlencode "id=6a9c5884000000002b002d95" \

from dataxapi import DataXAPI

dx = DataXAPI()  # reads DATAXAPI_API_KEY
result = dx.xiaohongshu.notes.comments.list(id="6a9c5884000000002b002d95")
print(result["data"]["items"])

第 3 步：小红书评论回复

挑回复多的评论，把它的 id 放进 id、post_id 放进 post_id，取这条评论下的回复。每条回复的 parent_id 是它直接回的那一条。

示例花多少钱

一页搜索结果，前 10 篇笔记各取第一页评论，再展开其中 3 条评论的回复

接口调用次数单价小计

小红书笔记搜索1$0.0200$0.0200

小红书笔记评论10$0.0200$0.20

小红书评论回复3$0.0200$0.0600

合计14$0.28

价格是生成本页时的现行价格。失败的调用、不存在的对象都不收费。

在 AI 里做（MCP）

把 DataXAPI 接进你的 AI 客户端，只要接一次。之后直接说要什么，代理自己找到这些接口、看好价格，用你的余额调用。

这样说: 在小红书搜“咖啡”，取前 10 篇笔记的第一页评论，再把回复最多的 3 条评论的回复取出来，整理成一张表。

代理发给 call 工具的参数

  "capability": "xiaohongshu.notes.search",

用 Skill 做

评论与口碑

“用户在这条内容下面夸什么、骂什么？”

“评论与口碑”这个 Skill 把这件事做成了现成的任务，带花费上限。它的示例运行：3 次调用，最多 $0.0060。

要知道的

评论一页通常 10 条、最多 20 条，只有一级评论，回复要用回复接口取。page.next_cursor 一小时内有效。
笔记编号是 24 位十六进制。编号对不上任何笔记时，评论接口返回“不存在”，不扣费；笔记下没有评论是空结果，照常扣费。回复接口分不清“评论不存在”和“没有回复”，都是空结果，照常扣费。
评论没有单独的链接（url）。IP 属地只在平台显示时才有，加 view=full，在 ext.ip_location 里。
