### Pubkey ### ### Pubkey
An administrative contact may be listed with a `pubkey`, in the same format as Nostr events (32-byte hex for a `secp256k1` public key). If a contact is listed, this provides clients with a recommended address to send encrypted direct messages (See `NIP-04`) to a system administrator. Expected uses of this address are to report abuse or illegal content, file bug reports, or request other technical assistance.

### Supported NIPs ### ### Supported NIPs
As the Nostr protocol evolves, some functionality may only be available by relays that implement a specific `NIP`. This field is an array of the integer identifiers of `NIP`s that are implemented in the relay. Examples would include `1`, for `"NIP-01"` and `9`, for `"NIP-09"`. Client-side `NIPs` SHOULD NOT be advertised, and can be ignored by clients. As the Nostr protocol evolves, some functionality may only be available by relays that implement a specific `NIP`.
