# Get Miner Reserves

`GET /api/v1/on-chain/miners/reserves`

## Request

- Base URL: `https://cryptodataapi.com`
- URL: `https://cryptodataapi.com/api/v1/on-chain/miners/reserves`
- Auth: API key in header `X-API-Key`

BTC miner pool reserves + 24h/7d/30d net flow per pool.

Tracks reward addresses for Foundry USA, AntPool, F2Pool, ViaBTC, and
Binance Pool. Most pools sweep balances immediately (low standing balance
is normal); the meaningful signal is the cumulative funded/spent delta
over rolling windows.

Net flow interpretation:
- **Negative net** (heavy spending): miners selling — bearish pressure
- **Positive net** (accumulation): miners holding — historically late-bear
- Windows show as `available: false` until enough snapshots have accrued
