feat: update and add new core-v3 endpoints

[KovacZan]

Summary

Added and updated core-v3 endpoints. Made it possible to work with dot notation. Had to adjust parameters like this:

"timestamp.from"?: number;
"timestamp.to"?: number;

instead of:

timestamp?: {
    from?: number;
    to?: number;
}

because GET method doesn't parse the object to dot notation.
