> Hourly funding-rate history per instrument.

```bash theme={null}
curl "https://api.polynode.dev/v3/perps/funding/btc?key=$POLYNODE_API_KEY"
```

```json theme={null}
{
  "data": [
    { "funding_rate": "0.0000125", "timestamp": 1783566000059 },
    { "funding_rate": "0.0000125", "timestamp": 1783562400068 }
  ],
  "more": true
}
```

Newest first, one entry per hourly funding event. Window with `start_timestamp` / `end_timestamp` (Unix ms):

```bash theme={null}
curl "https://api.polynode.dev/v3/perps/funding/btc?start_timestamp=1783000000000&key=$POLYNODE_API_KEY"
```

The current live rate and the next funding time are on the [ticker](/perps/market-data/tickers). Rates are per funding interval (hourly) — multiply by 24×365 for an annualized figure.
