# Google Proximity Beacon API . v1beta1

## Instance Methods

Gets the Proximity Beacon API's current public key and associated

### Method Details

`getEidparams(x__xgafv=None)`

    Gets the Proximity Beacon API's current public key and associated
    parameters used to initiate the Diffie-Hellman key exchange required to
    register a beacon that broadcasts the Eddystone-EID format. This key
    changes periodically; clients may cache it and re-use the same public key
    to provision and register multiple beacons. However, clients should be
    prepared to refresh this key when they encounter an error registering an
    Eddystone-EID beacon.

    Args:
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Information a client needs to provision and register beacons that
          # broadcast Eddystone-EID format beacon IDs, using Elliptic curve
          # Diffie-Hellman key exchange. See
          # [the Eddystone specification](https://github.com/google/eddystone/tree/master/eddystone-eid) at GitHub.
