HTTP RPC API

JSON RPC API

JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.

JSON-RPC 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) as data format.

JavaScript API

To talk to an ethereum node from inside a JavaScript application use the web3.js library, which gives a convenient interface for the RPC methods. See the JavaScript API for more.

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, “\0B0”) - 0x (size 0, “”) - WRONG: 0xf0f0f (must be even number of digits) - WRONG: 004200 (must be prefixed 0x)

Currently cpp-ethereum,go-ethereum and parity provide JSON-RPC communication over http and IPC (unix socket Linux and OSX/named pipes on Windows). Version 1.4 of go-ethereum, version 1.6 of Parity and version 0.8 of Pantheon onwards have websocket support.

The default block parameter

The following methods have an extra default block parameter:

When requests are made that act on the state of ethereum, 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.

These examples are configured for the hosted rivet.cloud service. If you are logged into the rivet.cloud dashboard, the examples should be populated with your API key so you can run them straight away.

}

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

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:

curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' https://YourApiKey.eth.rpc.rivet.cloud/

{"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:

keccack(LeftPad32(key, 0), LeftPad32(map position, 0))

This means to retrieve the storage on pos1[“0x391694e7e0b0cce554cb130d723a9d27458f9298”] we need to calculate the position with:

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))

The geth console which comes with the web3 library can be used to make the calculation:

> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> web3.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

Now to fetch the storage:

curl -X POST --data '{"jsonrpc":"2.0", "method": "eth_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' https://YourApiKey.eth.rpc.rivet.cloud/

{"jsonrpc":"2.0","id":1,"result":"0x000000000000000000000000000000000000000000000000000000000000162e"}

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

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 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
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{see above}],"id":1}' https://YourApiKey.eth.rpc.rivet.cloud/

eth_getLogs

Returns an array of all logs matching a given filter object.

Parameters
  1. Object - The filter options:

  • fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

  • toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

  • address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.

  • topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with “or” options.

  • blockhash: DATA, 32 Bytes - (optional) With the addition of EIP-234 (Geth >= v1.8.13 or Parity >= v2.1.0), blockHash is a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in the filter criteria, then neither fromBlock nor toBlock are allowed.

Example Parameters
params: [{
  "topics": ["0x000000000000000000000000a94f5374fce5edbc8e2a8697c15331677e6ebf0b"]

Flume

When used in conjunction with Flume, EtherCattle is able to serve additional API calls based on its index.

For now, we’ve added two new RPC calls:

  • flume_erc20ByAccount(address[, next]): Returns a list of the ERC20 tokens that the specified address has received. If the result set exceeds a certain limit, the result will include a next token, which can be passed to a subsequent call to get more results.

Example:

curl https://YourApiKey.eth.rpc.rivet.cloud/ --data '{"id": 1, "method": "flume_erc20ByAccount", "params": ["0x0a65659b64573628ff7f90226b5a8bcbd3abf075"]}'
{"jsonrpc":"","id":1,"result":{"items":["0x0027449bf0887ca3e431d263ffdefb244d95b555", "0xdde19c145c1ee51b48f7a28e8df125da0cc440be"]}}

Note

This API will return any ERC20 tokens the address has ever received; it is possible that those tokens are not currently present in the wallet.

  • flume_erc20Holders(address[, next]): Returns a list of the addresses that have received the specified ERC20 token. If the result set exceeds a certain limit, the result will include a next token, which can be passed to a subsequent call to get more results.

Example:

curl https://YourApiKey.eth.rpc.rivet.cloud/ --data '{"id": 1, "method": "flume_erc20Holders", "params": ["0xdde19c145c1ee51b48f7a28e8df125da0cc440be"]}'

Note

This API will return any accounts that have ever received the token; it is possible that those tokens are not currently present in the wallet.

In the future we may add additional APIs to be able to include current balances, along with the list of tokens received.
