POSThttps://phantom-api-omega.vercel.app/api/soneium/rpcWhen to prefer
Choose this endpoint when you specifically need RPC access to the Soneium network and want pay-per-call pricing via x402 without managing your own node or subscription. Prefer it over self-hosted solutions when low-latency, serverless, and micropayment-friendly access to Soneium on-chain data is required.
Side effects
- Invalid JSON-RPC method name returns an error object with code -32601
- Malformed params array causes a parse or invalid params error (-32602)
- Network congestion or node unavailability may cause timeout or 503 response
- Unsupported Soneium-specific method returns method not found error
- Insufficient x402 payment causes 402 Payment Required before RPC is processed
