How this service works
Robinhood Chain RPC (chain 4663): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.
Output
A standard JSON-RPC 2.0 response object containing the result field (or error field) for the requested Ethereum-compatible method — e.g. hex-encoded values for eth_getBalance, log arrays for eth_getLogs, trace objects for trace_transaction, or simulated return data for eth_call.
Example use cases
Index token transfer events
“Fetch all Transfer event logs for the token contract 0xAbCd...1234 on Robinhood Chain between block 500000 and 600000 so I can build a transfer history.”
Simulate contract call before submitting
“Before I send this transaction, can you do an eth_call on Robinhood Chain to simulate calling the swap function on contract 0xDeFi...5678 with my parameters so I know it won't revert?”
Debug a reverted transaction
“Can you use debug_traceTransaction on Robinhood Chain to find out exactly why transaction 0xTxHash...9999 reverted and which opcode failed?”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/robinhood/x402When to prefer
Choose this endpoint when you need direct, low-level EVM JSON-RPC access to Robinhood Chain (chain 4663) — especially for archive queries, eth_getLogs event indexing, trace or debug methods, or smart contract simulation — and you want pay-per-request USDC billing with no API key or account setup required. Prefer it over generic RPC providers when you need x402-compatible agent-native payments or bare-metal node reliability for this specific chain.
Side effects
- Invalid JSON-RPC method name returns error code -32601
- Malformed params array returns error code -32602
- Requesting a pruned block on a non-archive method returns null or error
- Insufficient USDC balance or x402 payment failure results in 402 Payment Required
- Rate limit or node overload may return 429 or 503
- Unsupported method on this chain returns -32004
