Daily per-ticker flow breakdown, newest first.

Same `flows` array you see embedded in the summary route, returned as a first-class resource so clients that only need the time series can skip the rest of the envelope.

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: "BTC" | "ETH";
  days: number;
  flows: Array<{
    date: string;                         // YYYY-MM-DD
    tickerFlows: Record<string, number>;  // $M per ticker
    total: number;                        // $M
  }>;
}

Example

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

curl -sS "http://localhost:3000/api/v1/etf/eth/daily?days=7" \
  -H "Authorization: Bearer cg_live_YOUR_KEY"

{
  "data": {
    "asset": "ETH",
    "days": 7,
    "flows": [
      {
        "date": "2026-04-17",
        "tickerFlows": { "ETHA": 22.1, "FETH": 18.4 },
        "total": 40.5
      }
    ]
  },
  "meta": { "total": 1, "days": 7, "asset": "ETH" }
}
