U.S. dollar broad trade-weighted index (FRED `DTWEXBGS`) — feed pending.

Dollar strength proxy — we use the FRED broad trade-weighted index rather than ICE's proprietary DXY so the feed stays fully free-tier. Inverse correlation to risk assets is well-documented. Stub returns an empty series with `meta.dataStatus = "not-yet-ingested"` until the FRED adapter lands.

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: "DTWEXBGS";
  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/dxy?days=180"

{
  "data": { "series": "DTWEXBGS", "source": "fred", "days": 180, "latest": null, "points": [] },
  "meta": { "total": 0, "days": 180, "dataStatus": "not-yet-ingested", "unavailable": "not-yet-ingested" }
}
