How this service works
Optimism RPC (chain 10): 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.
Output
A standard JSON-RPC 2.0 response object containing the result field with chain data (e.g. block details, transaction receipts, log arrays, call return values, trace objects) or an error object with code and message if the call fails.
Example use cases
Smart contract event indexing
“Fetch all Transfer events from the USDC contract on Optimism between block 115000000 and 115005000 using eth_getLogs — I need the full log data including topics and transaction hashes.”
DeFi transaction simulation
“Before I submit this swap transaction on Optimism, can you run eth_call with my calldata against the Uniswap router at 0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45 to simulate whether it will succeed and what the output amount will be?”
On-chain balance and state lookup
“Get the current ETH balance and the latest block number on Optimism chain 10 for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — just fire a couple of JSON-RPC calls and return the results.”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/op/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need direct, low-level JSON-RPC access to Optimism (chain 10) specifically, including archive data, trace_transaction, debug_traceCall, or eth_getLogs for event indexing — especially when you want to avoid API key registration and pay only for what you use in USDC micropayments. Prefer it over managed RPC providers when building AI agent workflows that need programmatic, accountless access to Optimism.
Side effects
- Invalid JSON-RPC method name returns error code -32601
- Malformed params array causes -32602 invalid params error
- Requesting a pruned block on a non-archive node returns missing trie node error
- Insufficient USDC payment balance causes payment rejection before the call is executed
- Rate limit or node overload may cause transient 503 responses
- eth_getLogs with too broad a filter may timeout or return too many results
