SiteCheck EVM RPC
x402
SiteCheck EVM RPC is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-04).
Execute read-only JSON-RPC calls against EVM-compatible blockchains (Ethereum, Base, Arbitrum, etc.) via a pay-per-call proxy

How this service works
Read-only JSON-RPC pass-through for 20+ EVM chains (ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, gnosis, linea, scroll, zksync, mantle, blast, celo, fantom, sonic, unichain, opbnb, zora, mode, metis, cronos). Single or batch calls (up to 10). Write methods refused.
Output
Returns a JSON object containing the target chain name, chain ID, RPC provider used, the full JSON-RPC 2.0 response (including the result field), a timestamp, and a disclaimer. For batch calls, results are returned for each sub-call.
Example use cases
Check current block height on Ethereum
“Can you get the latest block number on Ethereum mainnet using eth_blockNumber?”
Read smart contract state on Base
“Call the balanceOf function on the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base for wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — what's the token balance?”
Batch EVM queries across chains
“I need to batch-query eth_getBlockByNumber for the latest block on both Arbitrum and Base in a single call — can you do that?”
Technical details
Endpoint
POSThttps://api.sitecheck-api.workers.dev/api/rpc/evm?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, pay-per-call EVM JSON-RPC access without managing your own node or RPC provider API key. Ideal for agents that occasionally need on-chain reads across multiple chains (Ethereum, Base, Arbitrum) without committing to a subscription. Prefer over full node providers when cost-per-call economics matter and call volume is low-to-moderate.
Side effects
- Invalid chain name returns an error or empty response
- Unsupported JSON-RPC method rejected by upstream node
- Malformed params array causes RPC parse error
- Rate limiting or upstream node unavailability
- Write methods (eth_sendRawTransaction) not supported — read-only proxy
- Batch exceeds 10-call limit
