+.SH NAME
+eth-monitor-import \- Import transaction data from an indexing service
+
+
+.SH SYNOPSIS
+.SY eth-monitor-import
+[ -i \fIchain_spec\fP] [ --api-key-file \fIfile\fp ] [ --address-file \fIfile\fP ] [ -a \fIaddress\fP ... ] [ --cache-dir \fIdirectory\fP ] \fIservice\fP
+
+
+.SH DESCRIPTION
+Use an indexing service to retrieve transaction hashes for one or more addresses. Supported services may be listed using the \fB--list-services\fP option.
+.P
+Which addresses to retrieve data for may be defined by the \fB-a\fP \fIaddress\fP option. Alternatively, the \fB--address-file\fP \fIfile\fP option may be used, where addresses are supplied from the given file as a comma-separated list. The address matching mechanism used in transaction processing is the same as for \fBeth-monitor(1)\fP.
+.P
+Only block and transaction hashes are used from the indexing service. The RPC endpoint will be used to retrieve the block and transaction data.
+.P
+If \fB--cache-dir\fP \fIdirectory\fP is defined, data will be cached to the given path using the same caching filter as \fBeth-monitor(1)\fP. \fB--store-tx-data\fP and \fB--store-block-data-\fP define whether also transaction and block data is stored to cache, respectively.
