Xerxes eth_chainId RPC
x402
Xerxes eth_chainId RPC is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).
Returns the current chain ID of the connected Ethereum network as a hex string (e.g., '0x1' for mainnet).

How this service works
Returns the chain ID of the Ethereum network. No inputs. Output: chain ID as a hex string.
Output
Returns a JSON object with an 'ok' boolean, a 'hex' string (e.g. '0x1' for mainnet), a 'chain' string label, a 'result' integer (decimal chain ID), and a 'service' identifier. On failure, includes an 'error' field and ok=false.
Example use cases
Confirm mainnet before transaction
“Before I sign and broadcast this transaction, check what chain ID the RPC is on and tell me if it's Ethereum mainnet (0x1) or something else.”
Automated network sanity check
“At the start of my deployment script, verify that the Xerxes Ethereum RPC node is connected to mainnet by fetching the current chain ID.”
Debugging unexpected network
“My contract calls are behaving strangely — can you check what Ethereum network the Xerxes RPC endpoint is actually connected to right now by pulling the chain ID?”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/rpc_read_eth_chainid?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically verify which Ethereum network a Xerxes RPC node is connected to before executing transactions or contract calls — especially useful for safety checks, automated deployment pipelines, and multi-chain routing logic where chain identity must be confirmed.
Side effects
- RPC node unreachable — ok=false with error message
- Network timeout causing no response
- Unexpected chain ID if node is misconfigured or switched networks
- Payment failure (x402) if USDC balance insufficient
