 - [POST /public-keys](https://docs.vilna.io/ru/apis/platform/api/public_key/create-public-key.md): Register an extended public key for HD address derivation.
 - [DELETE /public-keys/{public_key_id}](https://docs.vilna.io/ru/apis/platform/api/public_key/delete-public-key.md): Delete a registered public key by ID, together with the addresses derived from it. An open invoice on any affected address returns 409.

The server derives the child extended public key using BIP-32 derivation: no cryptography needed on the client side. If a standalone
 - [GET /public-keys/{public_key_id}/addresses](https://docs.vilna.io/ru/apis/platform/api/public_key/list-public-key-addresses.md): List addresses derived from the public key.
 - [POST /public-keys/{public_key_id}/addresses](https://docs.vilna.io/ru/apis/platform/api/public_key/generate-public-key-addresses.md): Generate addresses for the public key, either a range of derivation indexes or the next unused one. An index that already has an address is returned unchanged; `label` and `meta` apply only to the add
