web3_clientVersion

POSThttps://triport.io/rpc/bsc

Return the selected node client version.

BNB Smart Chainbsc:rpcbsc_read_rpc - 15 / 20 / 100 / 250 RPS (free / basic / pro / business) (default, unmeasured); enterprise unlimited

web3_clientVersion returns the software version string reported by the selected BNB Smart Chain node.

Use it for diagnostics, compatibility investigation, or support data. Requests may be routed among eligible upstream nodes, so applications must not assume that the returned string is stable across calls.

This method identifies client software only. Use eth_chainId to verify the chain and eth_syncing to inspect synchronization state.

Parameters

JSON-RPC params must be an empty array: [].

Response

The response below is the checked fixture for this method; it is reproduced without changing its fields or values.

resultstring

Client version reported by the selected node.

Errors

Errors use the standard JSON-RPC error envelope. See BSC errors for network-specific classification and the linked shared reference.

Code	Meaning	When it happens
`-32602`	Invalid params	A required positional parameter is missing or a value does not match the OpenRPC schema.
`401`	Unauthorized	The `x-token` API key is missing or invalid.
`429`	Rate limited	The request exceeds the configured category RPS for the caller's tier.

const response = await fetch("https://triport.io/rpc/bsc", {
  method: "POST",
  headers: {
    "x-token": process.env.TRIPORT_API_KEY,
    "Content-Type": "application/json",

const payload = await response.json();
console.log(payload.result);

Notes

The BSC categories use configured defaults of 15 / 20 / 100 / 250 RPS; they are marked unmeasured in the tier matrix.
