The majority of monerod RPC calls use the daemon's `json_rpc` interface to request various bits of information. These methods all follow a similar structure, for example:
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
* Block blob data - array of strings; list of block blobs which have been mined. See [get_block_template](#get_block_template) to get a blob on which to mine.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
Block header information can be retrieved using either a block's hash or height. This method includes a block's hash as an input parameter to retrieve basic information about the block.
* *block_header* - A structure containing block header information. See [get_last_block_header](#get_last_block_header).
* *status* - string; General RPC error code. "OK" means everything looks good.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
Similar to [get_block_header_by_hash](#get_block_header_by_hash) above, this method includes a block's height as an input parameter to retrieve basic information about the block.
* *block_header* - A structure containing block header information. See [get_last_block_header](#get_last_block_header).
* *status* - string; General RPC error code. "OK" means everything looks good.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
Similar to [get_block_header_by_height](#get_block_header_by_height) above, but for a range of blocks. This method includes a starting block height and an ending block height as parameters to retrieve basic information about the range of blocks.
Alias: *getblockheadersrange*.
Inputs:
* *start_height* - unsigned int; The starting block's height.
* *end_height* - unsigned int; The ending block's height.
Outputs:
* *headers* - array of `block_header` (a structure containing block header information. See [get_last_block_header](#get_last_block_header)).
* *status* - string; General RPC error code. "OK" means everything looks good.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
In this example, blocks range from height 1545999 to 1546000 is looked up (notice that the returned informations are ascending order and that it is at the April 2018 network upgrade time):
```
$ curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_block_headers_range","params":{"start_height":1545999,"end_height":1546000}}' -H 'Content-Type: application/json'
Full block information can be retrieved by either block height or hash, like with the above block header calls. For full block information, both lookups use the same method, but with different input parameters.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
In the following example, block 912345 is looked up by its height. Note that block 912345 does not have any non-coinbase transactions. (See the next example for a block with extra transactions):
* *block_size_limit* - unsigned int; Maximum allowed block size
* *block_size_median* - unsigned int; Median block size of latest 100 blocks
* *bootstrap_daemon_address* - string; @Bootstrap-node to give immediate usability to wallets while syncing by proxying RPC to it. (Note: the replies may be untrustworthy).
* *cumulative_difficulty* - unsigned int; Cumulative difficulty of all blocks in the blockchain.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
* *was_bootstrap_ever_used* - boolean; States if a bootstrap node has ever been used since the daemon started.
* *earliest_height* - unsigned int; Block height at which hard fork would be enabled if voted in.
* *enabled* - boolean; Tells if hard fork is enforced.
* *state* - unsigned int; Current hard fork state: 0 (There is likely a hard fork), 1 (An update is needed to fork properly), or 2 (Everything looks good).
* *status* - string; General RPC error code. "OK" means everything looks good.
* *threshold* - unsigned int; Minimum percent of votes to trigger hard fork. Default is 80.
* *version* - unsigned int; The major block version for the fork.
* *votes* - unsigned int; Number of votes towards hard fork.
* *voting* - unsigned int; Hard fork voting status.
* *window* - unsigned int; Number of blocks over which current votes are cast. Default is 10080 blocks.

* *amount* - unsigned int; Output amount in @atomic-units
* *total_instances* - unsigned int;

Example:
```
$ curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_txpool_backlog"}' -H 'Content-Type: application/json'

## Other Daemon RPC Calls
Not all daemon RPC calls use the JSON_RPC interface. This section gives examples of these calls.
The data structure for these calls is different than the JSON RPC calls. Whereas the JSON RPC methods were called using the `/json_rpc` extension and specifying a method, these methods are called at their own extensions. For example:
Note: It is recommended to use JSON RPC where such alternatives exist, rather than the following methods. For example, the recommended way to get a node's height is via the JSON RPC methods [get_info](#getinfo) or [get_last_block_header](#get_last_block_header), rather than [getheight](#getheight) below.
For calls that end with **.bin**, the data is exchanged in the form of binary, serialized objects, as defined in the [Core RPC Server](https://github.com/monero-project/monero/blob/master/src/rpc/core_rpc_server_commands_defs.h).

* *Level* is one of the following:
* *FATAL* - higher level
* *ERROR*
* *WARNING*
* *INFO*
* *DEBUG*
* *TRACE* - lower level
A level automatically includes higher level.
By default, categories are set to `*:WARNING,net:FATAL,net.p2p:FATAL,net.cn:FATAL,global:INFO,verify:FATAL,stacktrace:INFO,logging:INFO,msgwriter:INFO`.
Setting the categories to "" prevent any logs to be outputed.
Alias: *None*.
Inputs:
* *categories* - string; Optional, daemon log categories to enable
Show information about valid transactions seen by the node but not yet mined into a block, as well as spent key image information for the txpool in the node's memory.
Alias: *None*.
Inputs: *None*.
Outputs:
* *spent_key_images* - List of spent output key images:
* *id_hash* - string; Key image.
* *txs_hashes* - string list; tx hashes of the txes (usually one) spending that key image.
* *status* - string; General RPC error code. "OK" means everything looks good.
* *status* - string; General RPC error code. "OK" means everything looks good.
* *tx_hashes* - binary array of transaction hashes.
* *untrusted* - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (`true`), or when the daemon is fully synced (`false`).
Example:
```
$ curl -X POST http://127.0.0.1:18081/get_transaction_pool_hashes.bin -H 'Content-Type: application/json'
{
"status": "OK",
"tx_hashes": " ... ",
