Kalichkin-adjusted NVT — CoinMetrics `NVTAdj`.

Thin wrapper around the CoinMetrics `NVTAdj` (Kalichkin-adjusted NVT) metric. We deliberately do NOT synthesise NVT locally from MarketCap and TxVolume — the adjustment smoothing is non-trivial and we'd drift from the value the cycle dashboard consumes. Empty series is a valid 200 for assets without an NVT feed.

Path parameters

Segments of the URL path, validated server-side.

Query parameters

All query parameters are optional unless marked required.

Response shape

Always wrapped in the standard envelope. Nullable fields are explicitly marked — treat missing numeric data as a real data-source gap, not as an error.

// Wrapped in the standard envelope:
// {
//   data: /* shape below */,
//   meta?: { total?: number; limit?: number; offset?: number; ... }
// }

{
  asset: string;
  days: number;
  metric: "NVTAdj";
  points: Array<{ ts: number; value: number }>;
}

Example

Copy the curl, replace YOUR_KEY with a real key from your dashboard, and run.

curl -sS "http://localhost:3000/api/v1/on-chain/BTC/nvt?days=365"

{
  "data": {
    "asset": "BTC",
    "days": 365,
    "metric": "NVTAdj",
    "points": [ { "ts": 1744761600000, "value": 84.2 } ]
  },
  "meta": { "total": 1, "days": 365 }
}
