'''Bitcoin API call list (as of version 0.3.20.2) with code samples and returned values.'''

== API Calls ==

API Calls to JSON-RPC are sent using POST method and parameters are sent as JSON object.

=== Example Request ===
When requesting something from the JSON-RPC server the request is sent to the server with the following URL: <tt>http://user:pass@localhost:8332/</tt> with post data that looks something like this:

<syntaxhighlight lang="javascript">{"method":"listreceivedbyaccount","params":[0],"id":"listreceivedbyaccount"}:</syntaxhighlight>

The Bitcoind server uses JSON notation instead of using regular POST parameters which can cause confusions sometime. Note the trailing colon on the post data above.

The JSON object that is being sent to the server is composed of 3 elements: <tt>method</tt>, <tt>params</tt>, and <tt>id</tt>.

<tt>method</tt> is what method you want to invoke, this is a simple string representing the method you're invoking.

<tt>params</tt> is the <tt>Array</tt> parameters that you're sending with the method invocation. Note that these parameters are sent as an <tt>Array</tt> notation and not <tt>Object</tt> notation.

<tt>id</tt> is used by the app requesting, and I usually just send the method name as the ID

== Calls List ==

Required arguments are denoted inside < and > Optional arguments are inside [ and ].

=== backupwallet ===

Safely copies wallet.dat to destination, which can be a directory or a path with filename.

==== Arguments ====

<tt>[0]</tt> <Destination> <tt>String</tt> The destination of the wallet file it will be copied to. This needs to be a valid <tt>directory</tt> in your file system passed in linux style (forward slashes (<tt>/</tt>) as separators - linux style, not backward slashes (<tt>\</tt>) - windows style). The directory must not have a file named <tt>wallet.dat</tt> otherwise the operation will fail. Example: <tt>"d:/wallet-backup/"</tt>

==== Example Request ====

<syntaxhighlight lang="javascript">{"method":"backupwallet","params":["d:/wallet-backup/"],"id":"backupwallet"}:</syntaxhighlight>

==== Result ====

===== Success =====
<tt>result</tt> = <tt>null</tt>

<syntaxhighlight lang="javascript">{
"result": null,
"error": null,
"id": "backupwallet"
}</syntaxhighlight>

===== Error =====
<syntaxhighlight lang="javascript">{
"result": null,
"error": {
"code": -1,
"message": "boost::filesystem::copy_file: The file exists: \"C:\\Users\\Eli\\AppData\\Roaming\\Bitcoin\\testnet\\wallet.dat\", \"d:\\wallet-backup\\wallet.dat\""
},
"id": "backupwallet"
}</syntaxhighlight>

There are other errors that can occur, for example if the directory provided is incorrect.

=== getaccount ===

==== Result ====
<tt>result</tt> = <tt>String</tt> the account that the address is associated with.

Note that some addresses in a bitcoin wallet are not associated with any given account and in those cases the <tt>result</tt> will be an empty string (i.e. the global account).

<syntaxhighlight lang="javascript">{
"result": "Testnet Faucet",
"error": null,
"id": "getaccount"
}</syntaxhighlight>

===== Error =====
The only time that this method returns an error is when the first argument (<tt>[0]</tt> Bitcoin Address) is not supplied. <ins>In any other case the method will return a successful result</ins> with an empty <tt>"result"</tt> value indicating that the address belongs to the global account, <ins>even if no address supplied</ins> (i.e. empty string: <tt>""</tt>) or a bad address altogether (i.e. <tt>"eli"</tt>).

<syntaxhighlight lang="javascript">{
"result": null,

"id": "getaccount"
}</syntaxhighlight>

=== getaccountaddress ===
