Illustrative response; amounts and dates are not current rates:

{
  "from": { "currency": "CAD", "amount": 100 },
  "to": { "currency": "COP", "amount": 260000 },
  "rate": 2600,
  "via": "ca-official+co-trm",
  "market": "ca_official+co_trm",
  "type": "official",
  "updated_at": "2026-10-21T00:00:00Z",
  "staleness_sec": 300,
  "stale": false,
  "legs": [
    { "via": "ca-official", "rate": 1.5, "updated_at": "2026-10-21T06:00:00Z", "stale": false },
    { "via": "co-trm", "rate": 3900, "updated_at": "2026-10-21T00:00:00Z", "stale": false }
  ]
}

rate is the second rate divided by the first. updated_at uses the older observation of the two legs. If either reference is unavailable, the conversion cannot be calculated.
