GET /chain/chain-id
unprobed
The EIP-155 chain ID for any supported network via eth_chainId — the read multi-chain agents make to confirm which chain an RPC is on before signing. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free public RPC; 6 chains vs onesource's Ethereum-only coverage.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
