How this service works
Soneium RPC (chain 1868): 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 with the requested blockchain data (block info, log events, call return values, trace output, etc.) or an 'error' object if the call fails. Response format matches the Ethereum JSON-RPC specification.
Example use cases
Index Soneium token transfer events
“Fetch all ERC-20 Transfer events emitted by contract 0x1234...abcd on Soneium between blocks 2000000 and 2005000 using eth_getLogs — I need to index recent activity for my dashboard.”
Simulate Soneium contract call before sending
“Run an eth_call on Soneium to simulate calling the 'balanceOf' function on contract 0xDEAD...BEEF for address 0xMY_WALLET so I can check the result without broadcasting a transaction.”
Trace a failed Soneium transaction
“Use the debug_traceTransaction method on Soneium chain 1868 to trace transaction 0xFAIL...HASH so I can figure out exactly where it reverted and why.”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/soneium/x402When to prefer
Choose this endpoint when you need permissionless, no-account RPC access to the Soneium network (chain 1868) and can pay per call in USDC via x402. Ideal for AI agents that need archive-depth queries (eth_getLogs over large ranges, debug/trace methods) without managing API keys or subscriptions. Prefer over free public RPCs when reliability and archive access matter, and over subscription RPCs when you want usage-based billing with no monthly commitment.
Side effects
- Invalid JSON-RPC method returns error code -32601
- Malformed params array causes -32602 invalid params error
- Insufficient USDC payment results in 402 Payment Required
- Block range too large for eth_getLogs causes timeout or range error
- Archive node methods unavailable if node is not in archive mode
- Rate limiting or overload returns 429 or 503
