web3_clientVersion

Polygon / https://triport.io/polygon

Minimum tier: Free

Polygon method guide

Last updated:

web3_clientVersion returns a free-form string identifying the client implementation and version serving the request. On Polygon mainnet (chainId 0x89 / 137) the network is secured by Bor, Polygon's fork of Geth, so the value typically begins with bor/v.... Depending on which backend serves a given request you may instead see a Geth/v... or erigon/v... string — the format is the client's own, not a Triport-defined schema.

Use this method as a cheap liveness ping or to record which client family is answering. Because the string reveals the client type and version, it can be used to fingerprint the backend; treat any client/version details as informational and do not branch critical logic on the exact string, since the serving node can change between requests.

This method takes no parameters and is available on every tier starting at free.
