Feeder gateway deprecation on December 11, 2023

All the methods listed here are working example counterparts to the deprecated feeder gateway. The interactive APIs are done based on the Pathfinder node.

Try out the Pathfinder-based interactive examples in each section and see the respective counterpart at the end of each section.

Starknet JSON-RPC version endpoints

Chainstack Starknet endpoints support sending requests to different JSON-RPC API versions. For versions, see the Pathfinder GitHub repository.

To send a request to a specific version, append your Chainstack Starknet endpoint with the version URL suffix. For example, /rpc/v0_6.

Check the following examples.

curl --request POST \
     --url https://starknet-mainnet.core.chainstack.com/365cf697a3ad6d950b4c4a911e2e4f4d/rpc/v0_4 \
     --header 'content-type: application/json' \
     --data '
{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "starknet_getNonce",
  "params": [
    {
      "block_number": 385940
    },
    "0x0569b13e8164bc8000c0bbcf4887856516643af123c5bc3b01e229e92f9cfd10"
  ]
}
