API 0 provides read-only access to the database, while API 1 is
used to login and gain access to additional, restricted API's.
TODO: the following examples use the old authority definition and thus do not work. They need to be updated.
Here is an example using `wscat` package from `npm` for websockets:

We can do the same thing using an HTTP client such as `curl` for API's which do not require login or other session state:
$ curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0, "get_accounts", [["1.3.0"]]], "id": 1}' http://127.0.0.1:8090/rpc

API 0 is accessible using regular JSON-RPC:
$ curl --data '{"jsonrpc": "2.0", "method": "get_accounts", "params": [["1.3.0"]], "id": 1}' http://127.0.0.1:8090/rpc
$ curl --data '{"jsonrpc": "2.0", "method": "get_accounts", "params": [["1.2.0"]], "id": 1}' http://127.0.0.1:8090/rpc
You can use the login API to obtain `network`, `database` and `history` API's. Here is an example of how to call `add_node` from the `network` API:
Accessing restricted API's
--------------------------
You can restrict API's to particular users by specifying an `apiaccess` file in `config.ini`. Here is an example `apiaccess` file which allows
user `bytemaster` with password `supersecret` to access four different API's:
{
"permission_map" :
[
[
"bytemaster",
{
"password_hash_b64" : "9e9GF7ooXVb9k4BoSfNIPTelXeGOZ5DrgOYMj94elaY=",
"password_salt_b64" : "INDdM6iCi/8=",
"allowed_apis" : ["database_api", "network_broadcast_api", "history_api", "network_node_api"]
}
]
]
}
Passwords are stored in `base64` as as salted `sha256` hashes. A simple Python script, `saltpass.py` is avaliable to obtain hash and salt values from a password.
A single asterisk `"*"` may be specified as username or password hash to accept any value.
With the above configuration, here is an example of how to call `add_node` from the `network_node` API:
{"id":1, "method":"call", "params":[1,"login",["bytemaster", "supersecret"]]}
{"id":2, "method":"call", "params":[1,"network",[]]}
{"id":2, "method":"call", "params":[1,"network_node",[]]}
{"id":3, "method":"call", "params":[2,"add_node",["127.0.0.1:9090"]]}
Note, the call to `network` is necessary to obtain the correct API identifier for the network API. It is not guaranteed that the network API identifier will always be `2`.
Note, the call to `network_node` is necessary to obtain the correct API identifier for the network API. It is not guaranteed that the network API identifier will always be `2`.

Questions
---------
@ -126,7 +189,15 @@ Questions
- Is there a way to generate help with parameter names and method descriptions?
Yes. Documentation of the code base, including APIs, can be generated using Doxygen. Simply run `doxygen` in this directory.
We are thinking of integrating Doxygen's XML output format to provide a better `help` command to the CLI wallet.
If both Doxygen and perl are available in your build environment, the CLI wallet's `help` and `gethelp`
commands will display help generated from the doxygen documentation.
If your CLI wallet's `help` command displays descriptions without parameter names like
`signed_transaction transfer(string, string, string, string, string, bool)`
it means CMake was unable to find Doxygen or perl during configuration. If found, the
output should look like this:
`signed_transaction transfer(string from, string to, string amount, string asset_symbol, string memo, bool broadcast)`
- Is there a way to allow external program to drive `cli_wallet` via websocket, JSONRPC, or HTTP?

The classes declared in these headers provide the complete definition of the
Graphene protocol and are organized according to feature. Nothing in this

in the protocol directory.
To be more specific, implementation details such as the objects defined in

/**
* @defgroup operations Operations
* @ingroup transactions Transactions
* @brief A set of valid comands for mutating the globally shared state.
*
* An operation can be thought of like a function that will modify the global
* shared state of the blockchain. The members of each struct are like function
* arguments and each operation can potentially generate a return value.
*
* Operations can be grouped into transactions (@ref transaction) to ensure that they occur
* in a particular order and that all operations apply successfully or
* no operations apply.
*
* Each operation is a fully defined state transition and can exist in a transaction on its own.
*
* @section operation_design_principles Design Principles
*
* Operations have been carefully designed to include all of the information necessary to
* interpret them outside the context of the blockchain. This means that information about
* current chain state is included in the operation even though it could be inferred from
* a subset of the data. This makes the expected outcome of each operation well defined and
* easily understood without access to chain state.
*
* @subsection balance_calculation Balance Calculation Principle
*
* We have stipulated that the current account balance may be entirely calculated from
* just the subset of operations that are relevant to that account. There should be
* no need to process the entire blockchain inorder to know your account's balance.
*
* @subsection fee_calculation Explicit Fee Principle
*
* Blockchain fees can change from time to time and it is important that a signed
* transaction explicitly agree to the fees it will be paying. This aids with account
* balance updates and ensures that the sender agreed to the fee prior to making the
* transaction.
*
* @subsection defined_authority Explicit Authority
*
* Each operation shall contain enough information to know which accounts must authorize
* the operation. This principle enables authority verification to occur in a centralized,
* optimized, and parallel manner.
*
* @subsection relevancy_principle Explicit Relevant Accounts
*
* Each operation contains enough information to enumerate all accounts for which the
* operation should apear in its account history. This principle enables us to easily
* define and enforce the @balance_calculation. This is superset of the @ref defined_authority

/**
* @defgroup proposed_transactions The Graphene Transaction Proposal Protocol
* @ingroup operations
*
* Graphene allows users to propose a transaction which requires approval of multiple accounts in order to execute.
* The user proposes a transaction using proposal_create_operation, then signatory accounts use
* proposal_update_operations to add or remove their approvals from this operation. When a sufficient number of
* approvals have been granted, the operations in the proposal are used to create a virtual transaction which is
* subsequently evaluated. Even if the transaction fails, the proposal will be kept until the expiration time, at
* which point, if sufficient approval is granted, the transaction will be evaluated a final time. This allows
* transactions which will not execute successfully until a given time to still be executed through the proposal
* mechanism. The first time the proposed transaction succeeds, the proposal will be regarded as resolved, and all
* future updates will be invalid.
*
* The proposal system allows for arbitrarily complex or recursively nested authorities. If a recursive authority
* (i.e. an authority which requires approval of 'nested' authorities on other accounts) is required for a
* proposal, then a second proposal can be used to grant the nested authority's approval. That is, a second
* proposal can be created which, when sufficiently approved, adds the approval of a nested authority to the first
* proposal. This multiple-proposal scheme can be used to acquire approval for an arbitrarily deep authority tree.
*
* Note that at any time, a proposal can be approved in a single transaction if sufficient signatures are available
* on the proposal_update_operation, as long as the authority tree to approve the proposal does not exceed the
* maximum recursion depth. In practice, however, it is easier to use proposals to acquire all approvals, as this
* leverages on-chain notification of all relevant parties that their approval is required. Off-chain
* multi-signature approval requires some off-chain mechanism for acquiring several signatures on a single
* transaction. This off-chain synchronization can be avoided using proposals.

* the chain's budget is exhausted before the worker is paid, that worker is simply not paid at that interval.
* Payment is not prorated based on percentage of the interval the worker was approved. If the chain attempts to pay
* a worker, but the budget is insufficient to cover its entire pay, the worker is paid the remaining budget funds,
* even though this does not fulfill his total pay. The worker will not receive extra pay to make up the difference
