Using the Cosmos API

Cosmos SDK exposes three primary interfaces for interacting with a node. Each interface is accessible through a different port:

  • gRPC: Port 9090
  • REST: Port 1317
  • CometBFT RPC: Port 26657

Nodes also expose other endpoints, such as the CometBFT P2P endpoint, or the Prometheus endpoint, which are not directly related to the Cosmos SDK. For detailed instructions on configuring these additional CometBFT endpoints, refer to the CometBFT Configuration Manual.

gRPC (Mainnet)

Below is an example of querying the gRPC server for governance proposals on Mainnet:

grpcurl -plaintext cosmos.xrplevm.org:9090 cosmos.gov.v1.Query/Proposals
Response (truncated example)
{
  "proposals": [
    {
      "id": "49",
      "messages": [
        {
          "@type": "/ethermint.evm.v1.MsgUpdateParams",
          ...
        }
      ],
      "status": "PROPOSAL_STATUS_PASSED",
      ...
    }
  ],
  "pagination": {
    "total": "49"
  }
}

For more details on the Cosmos SDK gRPC server, refer to the Cosmos SDK gRPC Server documentation.
The full gRPC server specification is available at buf.build/cosmos/cosmos-sdk.

REST API (Mainnet)

Example REST API query for governance proposals on Mainnet:

curl -X GET "http://cosmos.xrplevm.org:1317/cosmos/gov/v1/proposals" -H "accept: application/json"
Response (truncated example)
{
  "proposals": [
    {
      "id": "49",
      "messages": [
        {
          "@type": "/ethermint.evm.v1.MsgUpdateParams",
          ...
        }
      ],
      "status": "PROPOSAL_STATUS_PASSED",
      ...
    }
  ],
  "pagination": {
    "next_key": null,
    "total": "49"
  }
}

Learn more about the Cosmos REST server in the Cosmos SDK REST Server documentation.
Access the full REST API specification at cosmos.xrplevm.org:1317.

CometBFT RPC (Mainnet)

Example CometBFT RPC query for governance proposals on Mainnet:

curl -X GET 'http://cosmos.xrplevm.org:26657/abci_query?path="/cosmos.gov.v1.Query/Proposals"' -H "accept: application/json"
Response (truncated example)
{
  "jsonrpc": "2.0",
  "id": -1,
  "result": {
    "response": {
      "code": 0,
      "log": "",
      "info": "",
      "index": "0",
      "key": null,
      "value": "CqwCCAEShgEKKC9...dsZXR5am12cAESAhAx",
      "proofOps": null,
      "height": "13713161",
      "codespace": ""
    }
  }
}

Explore the Cosmos CometBFT RPC documentation for more details.
Access the CometBFT RPC interface at cosmos.xrplevm.org:26657.

With these endpoints, you can query governance proposals (and more) on the Mainnet, Testnet and Devent environments. The same commands can be adapted for other Cosmos SDK features, providing a versatile approach to interacting with the XRPL EVM’s Cosmos-based layer.
