Interact with the blockchain directly by connecting to the blockchain node and communicating with it through JSON-RPC.
Each node-related API supports its own set of the blockchains. The list of the supported blockchains is provided in the API description further in this section.
Connect to the blockchain node through an RPC driver
The number of credits consumed depends on the number of methods submitted in an API call:
* 50 credits per debug*/trace* method (for EVM-based blockchains)
* 50 credits per EOS Trace API methods
* 5 credits per eth_call method (for EVM-based blockchains)
* 2 credits per any other RPC method
Connect directly to the blockchain node provided by Tatum.
The POST method is used. The API endpoint URL acts as an HTTP-based RPC driver.
In the request body, provide valid Web3 RPC method content, for example:
{
"jsonrpc": "2.0",
"id": 1,
"method": "method_name",
"params": []
}
For the blockchains using the JSON-RPC 2.0 specification, you can submit multiple RPC methods in one API call:
[
{
"jsonrpc": "2.0",
"id": 1,
"method": "method_1_name",
"params": []
},
{
"jsonrpc": "2.0",
"id": 2,
"method": "method_2_name",
"params": []
},
...
]
