Example use cases
Check wallet balance on Superseed
“Can you check the ETH balance of wallet address 0xAbC123... on the Superseed network right now?”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/superseed/rpcWhen to prefer
Choose this endpoint when you specifically need to interact with the Superseed Layer 2 network via standard Ethereum JSON-RPC calls and want pay-per-call pricing without a subscription. Ideal for agents that need lightweight, on-demand access to Superseed blockchain state without managing their own node infrastructure.
Side effects
- Invalid or unsupported RPC method name returns a JSON-RPC error response
- Malformed params array causes a parsing or invalid-params error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network congestion or node unavailability may cause timeout or 503 errors
- Querying a non-existent contract address returns null or empty result
