How this service works
Arbitrum Nova RPC (chain 42170): 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) matching the requested method — e.g. hex-encoded values for eth_call, log arrays for eth_getLogs, structured trace objects for debug/trace methods, block or transaction objects for eth_getBlock/eth_getTransaction.
Example use cases
Index Arbitrum Nova contract events
“Fetch all Transfer event logs from the USDC contract on Arbitrum Nova between blocks 6000000 and 6010000 so I can index them.”
Simulate a transaction before sending
“Run eth_call on Arbitrum Nova for this contract interaction to check what the return value would be before I actually submit the transaction.”
Trace a failed transaction
“I have a transaction hash on Arbitrum Nova that reverted — can you run a debug trace on it so I can see exactly where it failed and why?”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/nova/x402When to prefer
Choose this endpoint when you need full EVM JSON-RPC access to Arbitrum Nova (chain 42170) specifically, including archive-depth queries, eth_getLogs for event indexing, eth_call simulations, or trace/debug methods. It is a strong choice for AI agents that need pay-per-request billing with no API key signup, particularly when using x402 micropayment flows. Prefer it over managed RPC providers when you want bare-metal node reliability and per-call USDC cost transparency on Nova.
Side effects
- Invalid or unsupported JSON-RPC method returns a JSON-RPC error object
- Malformed params array causes parse or invalid params error
- Insufficient USDC balance or x402 payment failure blocks the request
- Block range too large for eth_getLogs may return an error or timeout
- Requesting a pruned block on a non-archive node (not applicable here — archive is supported)
- Network or node downtime returns HTTP 5xx
