U.S. M2 money supply (FRED `M2SL`) — feed pending.

Seasonally-adjusted M2 in billions of dollars. The classic 'global liquidity' proxy — rising M2 has a loose, lagged correlation with crypto rallies. Stub returns an empty series with `meta.dataStatus = "not-yet-ingested"` until the FRED adapter is wired into ingestion.

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; ... }
// }

{
  series: "M2SL";
  source: "fred";
  days: number;
  latest: { ts: number; value: number } | null;
  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/macro/m2?days=365"

{
  "data": { "series": "M2SL", "source": "fred", "days": 365, "latest": null, "points": [] },
  "meta": { "total": 0, "days": 365, "dataStatus": "not-yet-ingested", "unavailable": "not-yet-ingested" }
}

Notes

• Series ID matches the FRED canonical identifier — safe to relay into charting libraries verbatim.
