How this service works
JSON-RPC read access to EVM chains (base, ethereum, polygon, arbitrum, optimism) with no API key. Send a standard JSON-RPC body (eth_call, eth_getBalance, eth_blockNumber, eth_getLogs). Also callable as GET with the same fields as query parameters.
Output
A standard JSON-RPC response object containing the 'result' field with the on-chain data (e.g. balance in wei, block number as hex, call return value, or array of log entries), or an 'error' field if the request failed.
Example use cases
Check DeFi wallet balance on Base
“Can you get the ETH balance of address 0xAbCd1234...5678 on the Base network right now?”
Read smart contract state on Polygon
“Call the totalSupply function on the USDC contract at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon — what does it return?”
Monitor latest block on Arbitrum
“What's the latest block number on Arbitrum right now?”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/rpc/:chain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, pay-per-call JSON-RPC access to multiple EVM chains without managing API keys or subscriptions. Ideal for agents that need occasional on-chain reads across Base, Ethereum, Polygon, Arbitrum, or Optimism at low cost ($0.002 per call) without provisioning infrastructure or signing up for Alchemy/Infura accounts.
Side effects
- Invalid chain name in path returns an error or 404
- Malformed JSON-RPC method name returns a JSON-RPC error response
- Invalid params format causes parsing failure
- eth_sendRawTransaction and write methods are not supported (read-only access)
- Network congestion may cause timeouts on complex eth_call requests
- Payment not fulfilled results in 402 Payment Required response
