+# JSON RPC API
+
+[JSON](http://json.org/) is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.
+
+[JSON-RPC](http://www.jsonrpc.org/specification) is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in many various message passing environments. It uses JSON ([RFC 4627](http://www.ietf.org/rfc/rfc4627.txt)) as data format.
+
+Geth 1.4 has experimental pub/sub support. See [this](https://github.com/ethereum/go-ethereum/wiki/RPC-PUB-SUB) page for more information.
+
+## JavaScript API
+
+To talk to a tangerine node from inside a JavaScript application use the [web3.js](https://github.com/ethereum/web3.js) library, which gives a convenient interface for the RPC methods.
+See the [JavaScript API](https://github.com/ethereum/wiki/wiki/JavaScript-API) for more.
+Extend API will support in the future.
+
+## JSON-RPC Endpoint
+
+Default JSON-RPC endpoints:
+
+| Client | URL |
+|-------|:------------:|
+| Go |http://localhost:8545 |
+
+### Go
+
+You can start the HTTP JSON-RPC with the `--rpc` flag
+```bash
+gtan --rpc
+```
+
+change the default port (8545) and listing address (localhost) with:
+
+```bash
+gtan --rpc --rpcaddr <ip> --rpcport <portnumber>
+```
+
+If accessing the RPC from a browser, CORS will need to be enabled with the appropriate domain set. Otherwise, JavaScript calls are limit by the same-origin policy and requests will fail:
+
+```bash
+gtan --rpc --rpccorsdomain "http://localhost:3000"
+```
+
+The JSON RPC can also be started from the [gtan console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console) using the `admin.startRPC(addr, port)` command.
+
+## HEX value encoding
+
+At present there are two key datatypes that are passed over JSON: unformatted byte arrays and quantities. Both are passed with a hex encoding, however with different requirements to formatting:
+
+When encoding **QUANTITIES** (integers, numbers): encode as hex, prefix with "0x", the most compact representation (slight exception: zero should be represented as "0x0"). Examples:
+- 0x41 (65 in decimal)
+- 0x400 (1024 in decimal)
+- WRONG: 0x (should always have at least one digit - zero is "0x0")
+- WRONG: 0x0400 (no leading zeroes allowed)
+- WRONG: ff (must be prefixed 0x)
+
+When encoding **UNFORMATTED DATA** (byte arrays, account addresses, hashes, bytecode arrays): encode as hex, prefix with "0x", two hex digits per byte. Examples:
+- 0x41 (size 1, "A")
+- 0x004200 (size 3, "\0B\0")
+- 0x (size 0, "")
+- WRONG: 0xf0f0f (must be even number of digits)
+- WRONG: 004200 (must be prefixed 0x)
+
+## The default block parameter
+
+The following methods have an extra default block parameter:
+
+- [eth_getBalance](#eth_getbalance)
+- [eth_getCode](#eth_getcode)
+- [eth_getTransactionCount](#eth_gettransactioncount)
+- [eth_getStorageAt](#eth_getstorageat)
+- [eth_call](#eth_call)
+
+When requests are made that act on the state o tangerine, the last default block parameter determines the height of the block.
+
+The following options are possible for the defaultBlock parameter:
+
+- `HEX String` - an integer block number
+- `String "earliest"` for the earliest/genesis block
+- `String "latest"` - for the latest mined block
+- `String "pending"` - for the pending state/transactions
+
+## Curl Examples Explained
+
+The curl options below might return a response where the node complains about the content type, this is because the --data option sets the content type to application/x-www-form-urlencoded . If your node does complain, manually set the header by placing -H "Content-Type: application/json" at the start of the call.
+
+The examples also do not include the URL/IP & port combination which must be the last argument given to curl e.x. 127.0.0.1:8545

+#### eth_getBalance
+
+Returns the balance of the account of given address.
+
+##### Parameters
+
+1. `DATA`, 20 Bytes - address to check for balance.
+2. `QUANTITY|TAG` - integer block number, or the string `"latest"`, `"earliest"` or `"pending"`, see the [default block parameter](#the-default-block-parameter)
+
+##### Example Parameters
+```js
+params: [
+ '0xc94770007dda54cF92009BFF0dE90c06F603a09f',
+ 'latest'
+]

+
+##### Returns
+
+`QUANTITY` - integer of the current balance in dal.
+
+
+##### Example
+```js
+// Request

+}
+```
+
+***
+
+#### eth_getStorageAt
+
+Returns the value from a storage position at a given address.
+
+##### Parameters
+
+1. `DATA`, 20 Bytes - address of the storage.
+2. `QUANTITY` - integer of the position in the storage.
+3. `QUANTITY|TAG` - integer block number, or the string `"latest"`, `"earliest"` or `"pending"`, see the [default block parameter](#the-default-block-parameter)
+
+##### Returns
+
+`DATA` - the value at this storage position.
+
+##### Example
+Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at `0x295a70b2de5e3953354a6a8344e616ed314d7251` by address `0x391694e7e0b0cce554cb130d723a9d27458f9298`.
+
+```
+contract Storage {
+ uint pos0;
+ mapping(address => uint) pos1;
+
+ function Storage() {
+ pos0 = 1234;
+ pos1[msg.sender] = 5678;
+ }
+}
+```
+
+Retrieving the value of pos0 is straight forward:
+
+```js
+curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' localhost:8545
+
+{"jsonrpc":"2.0","id":1,"result":"0x00000000000000000000000000000000000000000000000000000000000004d2"}
+```
+
+Retrieving an element of the map is harder. The position of an element in the map is calculated with:
+```js
+keccack(LeftPad32(key, 0), LeftPad32(map position, 0))
+```
+
+This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:
+```js
+keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))
+```
+The geth console which comes with the web3 library can be used to make the calculation:
+```js
+> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
+undefined
+> web3.sha3(key, {"encoding": "hex"})
+"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"
+```
+Now to fetch the storage:
+```js
+curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' localhost:8545

+#### eth_sign
+
+The sign method calculates an Tangerine specific signature with: `sign(keccak256("\x19Tangerine Signed Message:\n" + len(message) + message)))`.
+
+By adding a prefix to the message makes the calculated signature recognisable as an Tangerine specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
+
+**Note** the address to sign with must be unlocked.
+
+##### Parameters
+account, message
+
+1. `DATA`, 20 Bytes - address.
+2. `DATA`, N Bytes - message to sign.
+
+##### Returns
+
+`DATA`: Signature
+
+##### Example
+
+```js
+// Request
+curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "0xdeadbeaf"],"id":1}'

+
+#### eth_estimateGas
+
+Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.
+
+##### Parameters
+
+See [eth_call](#eth_call) parameters, expect that all properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.
+
+##### Returns
+
+`QUANTITY` - the amount of gas used.

+##### Example
+```js
+// Request
+curl -X POST --data '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{see above}],"id":1}'
