KTRENZ K-Data API

A free, public, read-only API for KTRENZ first-party K-pop data — measured AI-citation reach across answer engines plus external demand (Naver search + YouTube). Call it over plain REST, or connect any MCP-capable AI to use it as tools. No key.

+ Add to Cursor npm ↗GitHub ↗

Connect

Three ways in — all read-only, no key.

1 · REST (any HTTP client)

Four GET endpoints, JSON out, CORS-open, no key:

GET https://ktrenz.com/api/kdata/search?q=RESCENE
GET https://ktrenz.com/api/kdata/artist/{slug}
GET https://ktrenz.com/api/kdata/trending?limit=10
GET https://ktrenz.com/api/kdata/release/{slug}

Example response (trending)

{ "measured_by": "KTRENZ (ktrenz.com)",
  "as_of": "2026-07-30T…Z",
  "artists": [
    { "name": "RESCENE", "slug": "rescene",
      "demand": 74, "momentum_7d": 12.3,
      "reach_map_url": "https://ktrenz.com/reach-graph/artist/rescene" } ] }

2 · Remote MCP (Streamable HTTP · JSON-RPC)

https://ktrenz.com/api/mcp

curl -X POST https://ktrenz.com/api/mcp -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"get_trending","arguments":{"limit":5}}}'

3 · npm (stdio) — Claude Desktop & stdio clients

{
  "mcpServers": {
    "ktrenz-kdata": { "command": "npx", "args": ["-y", "ktrenz-mcp-kdata"] }
  }
}

Tools

search_kdata(query, limit?)

Find artists by name → slug + reach-map URL.

get_trending(limit?)

Top rising artists now by external demand (Naver search + YouTube). Rank is the signal.

get_release_reach(slug)

A release’s measured AI-citation reach across answer engines.
