Methods

The supported JSON-RPC methods on Humans.ai are listed below, organized by namespaces.

Curl Examples Explained

The curl parameters below could result in a response where the node complains about the content type since the --data option sets the content type to application/x-www-form-urlencoded. In the event that your node does complain, you can manually set the header by adding -H Content-Type: application/json at the beginning of the call.

Additionally, the URL/IP & port combination that must be the last argument given to curl, such as 127.0.0.1:8545, is not included in the samples.

eth_sign

The sign method determines a unique Ethereum signature using: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).

The calculated signature can be identified as an Ethereum-specific signature by adding a prefix to the message. This avoids abuse in which a malicious dApp might sign any data (such as a transaction) and then use the signature to pretend to be the victim.

danger

The signing address must be unlocked.

Parameters

  • Account Address

  • Message to sign

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70", "0xdeadbeaf"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

eth_getLogs

Returns the account toReturns a list of all the logs that match the specified filter object.

Parameters

  • Object containing:

    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: (optional, future) With the addition of EIP-234, blockHash will be 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 in the filter criteria, then neither fromBlock nor toBlock are allowed.

WebSocket Methods

Read about Websockets in Tendermint Events

eth_subscribe

Enables clients to subscribe to JSON-RPC notifications, providing a more efficient approach to receiving updates on specific events. This approach eliminates the need for clients to continuously poll for updates, reducing network congestion and improving overall performance. To utilize this feature, clients can subscribe to particular events by sending a request. Upon successful subscription, the node will return a unique subscription ID. Whenever an event occurs that matches the subscription criteria, the network will send a notification containing relevant data, along with the corresponding subscription ID.

Parameters

  • Subscription Name

  • Optional Arguments

// Request
{"id": 1, "method": "eth_subscribe", "params": ["newHeads", {"includeTransactions": true}]}

// Result
< {"jsonrpc":"2.0","result":"0x34da6f29e3e953af4d0c7c58658fd525","id":1}

eth_unsubscribe

Unsubscribe from an event using the Subscription ID

Parameters

  • Subscription ID
// Request
{"id": 1, "method": "eth_unsubscribe", "params": ["0x34da6f29e3e953af4d0c7c58658fd525"]}

// Result
{"jsonrpc":"2.0","result":true,"id":1}
