# JSON-RPC methods

### Filecoin RPC

You can review the official Filecoin RPC documentation [**HERE**](https://lotus.filecoin.io/reference/basics/overview/)

{% hint style="info" %}
Due to the computational resources consumed by certain RPCs, the free public RPC only supports the RPCs mentioned above. The rest of the JSON-RPCs will be intercepted and return a 403 status code.
