a plaintext string with the supported commands, space-separated, eg. `pay_invoice get_balance`. Only the `pay_invoice` command is described in this NIP, but other commands might be defined in different NIPs.
Both the request and response events SHOULD contain one `p` tag, containing the public key of the **wallet service** if this is a request, and the public key of the **user** if this is a response. The response event SHOULD contain an `e` tag with the id of the request event it is responding to.
Optionally, a request can have an `expiration` tag that has a unix timestamp in seconds. If the request is received after this timestamp, it should be ignored.
The content of requests and responses is encrypted with [NIP04](https://github.com/nostr-protocol/nips/blob/master/04.md), and is a JSON-RPCish object with a semi-fixed structure:

Description: Requests payment of multiple invoices.
Request:

{
"method": "multi_pay_invoice",

Response:
For every invoice in the request, a separate response event is sent. To differentiate between the responses, each
response event contains an `d` tag with the id of the invoice it is responding to, if no id was given, then the
payment hash of the invoice should be used.
