Xiaohongshu Creator Marketplace (Pugongying) Follower Growth History APIv1.0.0

MCN agencies pull 30/90-day follower growth histories for every managed KOL to populate internal dashboards that track momentum before, during, and after sponsored campaigns. The data helps account managers prove value to brands and reprice future deals based on real audience trajectory.

Brand marketing teams call the endpoint for shortlisted Xiaohongshu creators to confirm follower curves are organic and not spiking from purchased traffic. Comparing FANS_TOTAL and FANS_INCREASE over DAY_90 reveals suspicious flatlines or sudden jumps before a six-figure partnership is signed.

A vertical SaaS tool monitors the follower history of thousands of opted-in Xiaohongshu creators and triggers alerts when a creator's growth slope breaks a threshold. Subscribers use these alerts to spot breakout creators early and pitch them before their rates rise.

VC and PE analysts use the endpoint to assess whether a creator-founded DTC brand still benefits from the founder's organic audience growth. A declining 90-day follower trend signals weakening distribution leverage that can affect valuation and growth assumptions.

In-house social teams at beauty, fashion, and lifestyle brands benchmark top competitors' creators' follower growth against their own. The 30-day and 90-day histories expose which content formats or posting cadences correlate with sustained audience expansion.

JustOneAPI charges for API access to the Xiaohongshu Creator Marketplace follower growth endpoint through token-authenticated subscriptions or pay-per-call credits. Customers pay for reliable, normalized access without managing Xiaohongshu sessions or anti-bot infrastructure themselves.

Creator analytics and influencer marketing platforms integrate the endpoint as a data source behind their own product interfaces. They resell derived insights — growth scorecards, trend charts, creator rankings — to brands and agencies at a markup while JustOneAPI earns API fees.

A tool offers basic follower history lookups for free to attract individual creators and small agencies, then charges for bulk exports, historical data downloads, and API access. The free tier builds adoption while paid API calls and exports drive recurring revenue.
