.SH NAME
lightning-decode - Command for decoding an invoice string (low-level)
.SH SYNOPSIS
\fBdecode\fR \fIstring\fR
.SH DESCRIPTION
The \fBdecode\fR RPC command checks and parses a \fIbolt11\fR or \fIbolt12\fR
string (optionally prefixed by \fBlightning:\fR or \fBLIGHTNING:\fR) as
specified by the BOLT 11 and BOLT 12 specifications\. It may decode
other formats in future\.
.SH RETURN VALUE
