How this service works
Premium multi-chain RPC call via Alchemy/Helius.
Output
Returns the standard JSON-RPC result object for the invoked method, containing chain-specific data such as balances, block details, transaction receipts, contract return values, or other on-chain state, routed through premium Alchemy or Helius infrastructure.
Example use cases
Fetch on-chain account balance
“Can you use a premium Ethereum RPC node to call eth_getBalance for address 0xAbCd1234... on mainnet and tell me the balance in wei?”
Retrieve Solana transaction status
“Use a Helius-backed RPC to call getTransaction on Solana mainnet for signature 5KtP...xyz and give me the full transaction details.”
Query smart contract state
“Make an eth_call on Ethereum mainnet to the USDC contract at 0xA0b86991c... using the balanceOf method with my wallet address 0x1234abcd... as the parameter.”
Technical details
Endpoint
POSThttps://gateway.spraay.app/api/v1/rpc/callWhen to prefer
Choose this endpoint when you need reliable, low-latency JSON-RPC access to multiple blockchains (Ethereum ecosystem or Solana) through premium node providers without managing your own API keys or node infrastructure. Ideal for agents that need occasional or burst on-chain queries on a pay-per-call basis rather than a monthly subscription.
Side effects
- Unsupported chain identifier returns an error
- Invalid RPC method name returns JSON-RPC error code -32601 (method not found)
- Malformed params array causes -32602 (invalid params)
- Payment failure blocks the call with HTTP 402
- Node provider (Alchemy/Helius) downtime or rate limit propagates as 5xx error
- Requesting archival data on a non-archive endpoint returns null or error
