}Mean Coin Age
Mean Coin Age is the mean, over unspent outputs, of age in days multiplied by amount — like Coin Days Destroyed, but over the coins that are still held rather than the ones being spent.

}What it measures
Mean Coin Age is the mean, over unspent outputs, of age in days multiplied by amount — like Coin Days Destroyed, but over the coins that are still held rather than the ones being spent. Mean Coin Dollar Age additionally weights each output by the USD price when it was created. 📖 Data Guide: Mean Coin Age (MCA) — definition, interpretation, and chart examples.Assets and windows
| Asset class | What it covers | Assets | Windows |
|---|---|---|---|
| Bitcoin | the native asset of Bitcoin, asset=btc | btc | block · hour · day |
day.
Response fields
The time key depends on the window:datetime for day and hour and blockheight plus datetime for block.
| Field | Type | Description |
|---|---|---|
mca | number | Mean Coin Age — the mean, over unspent outputs, of the output’s age in days multiplied by its amount. |
mcda | number | Mean Coin Dollar Age — the mean, over unspent outputs, of the output’s age in days multiplied by its amount and by the USD price when it was created. |
Authorizations
For each API request, include the Authorization HTTP header with Bearer {access_token}.
Query Parameters
Asset to query, by its CryptoQuant alias (no chain suffix — usdt, not usdt_eth). 1 asset is available on this endpoint, across the asset class btc. Enumerate them with /v2/discovery/endpoints.
Chain the asset lives on. Optional for an asset that exists on exactly one chain, required when the same alias exists on several.
bitcoin Aggregation window. Which windows are valid depends on the asset — see the endpoint page. Defaults to day.
block, hour, day Inclusive start time, YYYYMMDDTHHMMSS (UTC). If window=day, YYYYMMDD is also accepted.
Inclusive end time, YYYYMMDDTHHMMSS (UTC). If window=day, YYYYMMDD is also accepted.
Maximum rows returned (default 100, max 10000).
x <= 10000Response format: json (default) or csv.
