How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a standard JSON-RPC response object containing an 'id', 'jsonrpc' version field, and a 'result' field with the requested on-chain data (e.g. balance in hex wei, block object, transaction receipt, contract call output) or an 'error' object with code and message if the call failed.
Example use cases
Check Gnosis wallet balance
“What's the xDai balance of wallet address 0xDe0B295669a9FD93d5F28D9Ec85E40f4cb697BA on Gnosis Chain right now?”
Read smart contract state on Gnosis
“Call the 'totalSupply' function on the smart contract at 0x4ECaBa5870353805a9F068101A40E0f32ed605C3 on Gnosis Chain and tell me the result.”
Broadcast signed transaction to Gnosis
“Submit this signed raw transaction to the Gnosis network: 0xf86c0185012a05f200825208943535353535...”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/gnosis/rpcWhen to prefer
Choose this endpoint when you need EVM-compatible JSON-RPC access specifically to the Gnosis Chain (xDai) network — for reading balances, querying contract state, or broadcasting transactions on that chain. Prefer it over general Ethereum RPC endpoints when your contract, token, or DeFi protocol is deployed on Gnosis. Use it for pay-per-call access without needing a dedicated RPC subscription.
Side effects
- Invalid RPC method name returns JSON-RPC error code -32601 (Method not found)
- Malformed params array causes -32602 (Invalid params) error
- Network congestion or node unavailability results in 503/timeout
- Submitting an already-mined transaction returns 'nonce too low' error
- Insufficient payment (x402) causes 402 response before RPC call is attempted
- Calling a non-existent contract address returns null or empty result without explicit error
