How do I query the dollar indices?

One authenticated GET returns the latest value with its timestamp and source. Swap the language tab for your stack.

$ curl https://api.exchangerate.dev/v1/indices/dxy-reconstructed \
    -H "Authorization: Bearer $API_KEY"
# → value, data_updated_at, source

const r = await fetch("https://api.exchangerate.dev/v1/indices/dxy-reconstructed", {
  headers: { Authorization: `Bearer ${API_KEY}` }
}).then(res => res.json())
console.log(r.value, r.data_updated_at, r.source)

r = requests.get(
    "https://api.exchangerate.dev/v1/indices/dxy-reconstructed",
    headers={"Authorization": f"Bearer {API_KEY}"},
).json()
print(r["value"], r["data_updated_at"], r["source"])

✓The response includes the index value, its weights, source, and data_updated_at.

Methodology

The six-currency reconstruction is heavily influenced by EUR because its published exponent is 57.6%. The EXR index spreads weight evenly across 13 currencies and includes developed and emerging-market currencies absent from that basket.

The comparison chart normalizes both series to 100 at the first shared point. This compares movement rather than absolute index levels; the original endpoint values remain available in the table and API.

The DXY line shown here is our independent formula reconstruction from exchangerate.dev observations. We do not redistribute official ICE index values on this page.

A point is emitted only when every constituent is present. Intraday timestamps must be within 30 seconds; missing baskets remain gaps and weights are never redistributed.
