Daily unique active addresses (sender or receiver) — CoinMetrics `AdrActCnt`.

Count of unique addresses that appeared as either sender or receiver in the 24h window. A clean proxy for on-chain usage. Available for every asset the CoinMetrics poller covers; empty series is a valid 200 for anything else.

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: "AdrActCnt";
  points: Array<{ ts: number; value: number }>;
}
