Safex Daemon RPC Documentation

This is a list of the safex daemon(safexd) RPC calls, their inputs and outputs, and examples of each. There are 3 types of RPC calls used: JSON, Protobuf and custom interface.

Note: Safex blockchain has two currency allowed within. Safex Cash (Safex) and Safex Token (SFT). Safex Cash is divisible up to 10 decimal places. Every value is rendered in atomic units. Atomic unit refer to smallest fraction of 1 Safex coin.

NOTE2: Safex Tokens are not divisible but value is still expressed in atomic units.

Protobuf RPC methods:

Other RPC methods:

Outputs:

  • block_header - A structure containing block header information.

get_block_header_by_hash

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.

Alias: getblockheaderbyhash.

Inputs:

  • hash - string; The block's sha256 hash.

Outputs:

  • block_header - A structure containing block header information. See get_last_block_header.
  • status - string; General RPC error code. "OK" means everything looks good.

In this example, block 660300 is looked up by its height (notice that the returned information is the same as in the previous example):

$ curl http://127.0.0.1:17402/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_block_header_by_height","params":{"height":660300}}' -H 'Content-Type: application/json'

},
"status": "OK",
"untrusted": false
}
}

get_block_headers_range

Similar to 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).
  • 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 http://127.0.0.1:17402/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_block_headers_range","params":{"start_height":133122,"end_height":133123}}' -H 'Content-Type: application/json'

get_block

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.

Alias: getblock.

Inputs (pick one of the following):

  • height - unsigned int; The block's height.
  • hash - string; The block's hash.

Outputs:

  • blob - string; Hexadecimal blob of block information.
  • block_header - A structure containing block header information. See get_last_block_header.
  • json - json string; JSON formatted block details:
    • major_version - Same as in block header.
    • minor_version - Same as in block header.
    • timestamp - Same as in block header.
    • prev_id - Same as prev_hash in block header.
    • nonce - Same as in block header.
    • miner_tx - Miner transaction information
      • version - Transaction version number.
      • unlock_time - The block height when the coinbase transaction becomes spendable.
      • vin - List of transaction inputs:
        • gen - Miner txs are coinbase txs, or "gen".
          • height - This block height, a.k.a. when the coinbase is generated.
      • vout - List of transaction outputs. Each output contains:
        • amount - The amount of the output, in atomic units.
        • target - txout_target_v
          • key - crypto::public_key
      • extra - Usually called the "transaction ID" but can be used to include any random 32 byte/64 character hex string.
      • signatures - Contain signatures of tx signers. Coinbased txs do not have signatures.
    • tx_hashes - List of hashes of non-coinbase transactions in the block. If there are no other transactions, this will be an empty list.
  • 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).

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:

IP=127.0.0.1
PORT=18081
METHOD='gettransactions'
PARAMS='{"txs_hashes":["d6e48158472848e6687173a91ae6eebfa3e1d778e65252ee99d7515d63090408"]}'
curl \
  http://$IP:$PORT/$METHOD \
  -d $PARAMS \
  -H 'Content-Type: application/json'

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 or get_last_block_header, rather than 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.
