TikTok Trends API

TikTok's Research API is limited to vetted academic institutions and does not return hashtag search interest in any normalized, time-series format. For developers building trend tools, content dashboards, or market research products, that data has been effectively inaccessible.

Trends MCP provides it via a single REST endpoint. Same auth, same request shape as every other source - just swap the source field.

Endpoint

POST https://api.trendsmcp.ai/api
Authorization: Bearer YOUR_API_KEY
