Read-only JSON-RPC passthrough
POST https://agent402.tools/api/eth-call
Escape hatch for power users: forward an arbitrary read-only JSON-RPC method to the chain. Method must be in our read-only whitelist (eth_call, eth_getLogs, eth_getBlockByNumber, eth_getTransactionReceipt, eth_chainId, eth_blockNumber, etc.). Mutating methods (eth_sendTransaction, eth_sendRawTransaction) are rejected - sign and broadcast through your own provider.
Warnings
Wallet mismatch The payout wallet in its live payment answer differs from its catalogue listing on the same network.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
