How this service works
Base RPC endpoint, pay per call: any allowlisted read-only JSON-RPC method on Base mainnet (eth_call, eth_getBalance, eth_getLogs, eth_getBlockByNumber, eth_getTransactionReceipt and more) with your own params, no API key. Revert reasons come back as the result. Input: method; optional params.
Output
A JSON-RPC response object containing the 'result' field with the chain's answer (e.g. hex balance, block object, log array, call return data). If the chain returns an error such as a revert reason or 'block not found', it is returned in the result rather than as a request failure — it is the chain's authoritative response to that exact call.
Example use cases
Check ERC-20 token balance on Base
“Call eth_call on Base mainnet to read the USDC balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 from the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Fetch latest block metadata
“Run eth_getBlockByNumber on Base mainnet for the latest block and return the full block details including timestamp and transaction count.”
Retrieve contract event logs
“Use eth_getLogs on Base mainnet to pull all Transfer events from the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 between blocks 12000000 and 12001000.”
Technical details
Endpoint
POSThttps://hubvibe-io.com/work/chain/rpc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to query Base mainnet on-chain data — balances, contract state, logs, blocks, transactions — without provisioning your own RPC node or managing API keys for a separate provider. It is ideal for read-only calls (eth_call, eth_getLogs, eth_getBalance, eth_getBlockByNumber, eth_getTransactionReceipt, etc.) where you want a simple pay-per-call model via x402. Prefer this over self-hosted RPC when building lightweight agents that need occasional Base mainnet reads without infrastructure overhead.
Side effects
- Method not in allowlist — only read-only methods are permitted; write methods like eth_sendRawTransaction are rejected
- Malformed params array causes JSON-RPC parse error returned in result
- Contract reverts — revert reason returned as result, not HTTP error
- Block not found for specified block number — returned as RPC error in result
- Payment failure — x402 payment of 0.05 USDC not accepted, request blocked
- Rate limiting if too many calls are made in quick succession
