NodeFlare Ethereum Mainnet RPC (Chain 1)
x402
NodeFlare Ethereum Mainnet RPC (Chain 1) is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Executes arbitrary Ethereum mainnet JSON-RPC calls — including eth_getLogs, eth_call, trace, and debug — on NodeFlare's bare-metal archive nodes, billed per request in USDC via x402 with no API key required.

How this service works
Ethereum RPC (chain 1): 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 either a `result` field with the method's return value (e.g. hex-encoded balance, array of log objects, call return data, trace array) or an `error` field with a code and message describing what went wrong.
Example use cases
Index ERC-20 transfer events
“Fetch all Transfer event logs from the USDC contract on Ethereum mainnet between blocks 19500000 and 19510000 so I can build a transfer history index.”
Simulate a contract call before sending
“Run eth_call on Ethereum mainnet to check what the balanceOf function returns for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on the USDC contract — without actually sending a transaction.”
Trace a failed transaction for debugging
“Use debug_traceTransaction on Ethereum mainnet to get the full execution trace for tx hash 0x4e3a3754410177e6937ef1f84bba68ea139e8d1a2258c5f85db9f1cd715a1bdf so I can see where it reverted.”

Endpoint
POSThttps://rpc.nodeflare.app/eth/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need direct, low-level Ethereum mainnet JSON-RPC access — especially archive methods like eth_getLogs over wide block ranges, debug_traceTransaction, or trace_* calls — without managing API keys or monthly subscriptions. It is ideal for AI agents that need pay-as-you-go, autonomous Ethereum data access billed in USDC via x402, and is particularly well-suited to indexing pipelines, event log queries, transaction simulations, and on-chain debugging tasks.
Side effects
- Invalid or unsupported RPC method name returns a JSON-RPC error with code -32601
- Malformed params array causes -32602 invalid params error
- Requesting a pruned historical block on a non-archive path returns null or error
- Rate or compute-unit budget exceeded returns HTTP 402 or payment-required error
- Network or node unavailability returns HTTP 5xx or timeout
- Block range too large for eth_getLogs returns -32005 limit exceeded error
