# Mainnet Integration

For using the Mainnet change the NAG url to `https://circularlabs.io/NAG_Mainnet.php?cep=` with the setNAGURL method.

```python
from circular_protocol_api import CircularProtocolAPI

circular = CircularProtocolAPI()
circular.setNAGURL("https://circularlabs.io/NAG_Mainnet.php?cep=")
```
