# Available history dates by rate ID

> Use GET /v2/fx/historical-limits for the first and last observations of rates visible to your plan; gaps may remain.

`GET /v2/fx/historical-limits` shows the first and last observation for each rate available to your plan. It requires an API key and counts as one request.

```bash curl theme={null}
curl "https://api.cotizave.com/v2/fx/historical-limits" \
  -H "X-API-Key: $COTIZAVE_API_KEY"
```

Illustrative response: the authenticated route includes rates available to your plan, including non-official rates with history.

```json theme={null}
{
  "base": "USD",
  "count": 2,
  "limits": [
    { "id": "ve-bcv", "country": "VE", "quote": "VES", "first": "2026-11-03", "last": "2026-11-05", "days": 3 },
    { "id": "ve-paralelo", "country": "VE", "quote": "VES", "first": "2026-11-04", "last": "2026-11-05", "days": 2 }
  ]
}
```

`days` counts days with data. There may be gaps between `first` and `last`.
