How this service works
Bounded rpc.call discovery challenge
Output
Returns the result of one or more RPC method invocations on the specified blockchain chain, including method return values or error details for each call. For batch calls, each item in the batch is resolved according to the quorum setting.
Example use cases
Query latest Ethereum block number
“Call the eth_blockNumber RPC method on Ethereum mainnet (chainId '1') and tell me what the current block number is.”
Batch ERC-20 balance lookups
“Send a batch of up to 5 eth_call RPC requests on chain '137' (Polygon) to check the token balances for these wallet addresses across the same ERC-20 contract — I need all results in one shot.”
Read smart contract state via eth_call
“I need to read the current price from a Uniswap pool contract on Ethereum — can you execute an eth_call RPC method on chainId '1' with the getReserves params for that contract address?”
Technical details
Endpoint
POSThttps://api.clervo.dev/v1/rpc/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to execute one or more blockchain RPC calls (such as eth_call, eth_blockNumber, or custom contract methods) on a specific chain without managing your own RPC node infrastructure. It is well-suited for agents needing programmatic, pay-per-call access to on-chain data or smart contract state, especially when batching up to 20 calls in a single request or requiring quorum-based multi-call resolution.
Side effects
- Invalid or unsupported chainId returns an error response
- RPC method not found or unsupported on the target chain
- Batch exceeds maxItems limit of 20 calls
- Quorum value outside the allowed range of 1-3
- Malformed call params cause a parse or execution error
- Payment not completed (x402 payment required) results in 402 response
- Network timeout or unavailable RPC node returns a connectivity error
