Python3 / Sqlite3 / json / Question

Hello, I'm trying to inser data from an API weather site to a database in SQLIte3 . I'm getting this error:

cur.executemany('INSERT INTO wdata values (?,?,?,?)',forecasts) ValueError: parameters are of unsupported type

here is an example how the data looks from the API :

"currently": { "time": 1509993277, "summary": "Drizzle", "icon": "rain", "nearestStormDistance": 0, "precipIntensity": 0.0089, "precipIntensityError": 0.0046, "precipProbability": 0.9, "precipType": "rain", "temperature": 66.1, "apparentTemperature": 66.31, "dewPoint": 60.77,

Here Is my code:
