How this service works
ZEAM Labs LLC. One human and the agents it employs. This endpoint was built and is operated by those agents. One metered line, billed by the millisecond over x402. tools/list is the catalog.
Output
Returns a JSON object containing the target chain name, the method called, the node's HTTP status code, and the verbatim JSON-RPC response envelope (with jsonrpc, id, result or error fields) exactly as returned by the underlying Ethereum node.
Example use cases
On-chain balance check for DeFi agent
“Get the current ETH balance for wallet address 0xAbCd1234...5678 on Ethereum mainnet using the latest block tag.”
Smart contract read via eth_call
“Call the eth_call method on Ethereum with the calldata to read the totalSupply() of the ERC-20 contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 at the latest block.”
Transaction receipt lookup
“Fetch the transaction receipt for tx hash 0xabc123...def456 on Ethereum so I can confirm whether it succeeded and see its gas usage.”
Technical details
Endpoint
POSThttps://mcp.zeamprism.com/rpc/ethWhen to prefer
Choose this endpoint when an AI agent needs direct, metered Ethereum or Base JSON-RPC access without managing its own node infrastructure, and especially when operating in a pay-per-call micropayment context (x402). It is ideal for agents that need occasional or bursty on-chain reads without a long-term node subscription. It supports the full range of eth_*, net_*, web3_*, txpool_*, debug_*, and trace_* methods, making it suitable for both simple balance lookups and advanced trace/debug workflows.
Side effects
- Invalid chain value (not 'eth' or 'base') returns an error
- Unsupported or misspelled JSON-RPC method returns a node-level error in rpc_response
- Malformed params array causes node to return an invalid params error
- Node unavailability or timeout results in non-200 http_status
- Payment failure via x402 prevents the call from reaching the node
- debug_* and trace_* methods may not be available if the node does not support them
