Xiaohongshu Data Competitor Analysis Brand Monitoring

RedNote (Xiaohongshu) is a rich source of brand reputation and competitor signals. This hands-on guide shows how to build a "competitor + brand" monitoring pipeline with the Rnote API — chaining search, notes, creators, and comments into a reusable monitoring dashboard.

What to monitor

  • Share of voice — Volume and posting trend of brand / competitor notes
  • Engagement — Likes, collects, and comments over time
  • Reputation — Real praise and complaints inside comments
  • Creators — Who's selling for competitors and which influencers they work with

Build the pipeline in four steps

  1. Capture share of voice — Use keyword search search/notes to periodically collect notes for brand/competitor terms and tally volume and engagement.
  2. Grab media — For top notes, use the watermark-free image/video endpoint to archive covers and content for visual and topic analysis.
  3. Mine reputation — For key notes, pull comments via the comments endpoint note/comments and run sentiment and keyword analysis.
  4. Profile creators — For frequently appearing authors, fetch profiles via the creator endpoint user/info to map a competitor's creator matrix.

A minimal example (Python)

import requests

API = "https://rnote.dev/api/v2/crawler"
H = {"X-API-Key": "YOUR_API_KEY"}

def monitor(brand):
    # 1) Search newest notes for the brand term
    notes = requests.get(f"{API}/search/notes",
                         params={"keyword": brand, "sort_type": "time_descending"},
                         headers=H).json()

    # 2) Pull comments per note for sentiment analysis
    for note in iter_notes(notes):           # iterate per response shape
        nid = note["note_id"]
        comments = requests.get(f"{API}/note/comments",
                                params={"note_id": nid},
                                headers=H).json()
        yield nid, comments

# Persist results and run on a schedule (e.g., daily cron) to build a trend dashboard

Production tips

  • Scheduled & incremental — Run a daily cron, dedup by note_id, process only new items.
  • Store + visualize — Persist share-of-voice/engagement/sentiment to a database and chart trends with a BI tool.
  • Cost control — Only successful requests are billed, ideal for scheduled jobs; validate rules on a small batch, then scale.
