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 the raw JSON-RPC response from the Injective blockchain node, including result data (account balances, block info, transaction receipts, contract state) or an error object with code and message if the call fails.
Example use cases
Query Injective account balance
“Call the Injective RPC with method 'cosmos.bank.v1beta1.Query/AllBalances' and params for my address inj1abc123... and tell me what tokens I'm holding.”
Fetch latest Injective block info
“Use the Injective RPC to call 'eth_getBlockByNumber' with params ['latest', true] so I can see the most recent block details on the Injective network.”
Broadcast transaction to Injective
“I need to submit a signed transaction to the Injective chain — call the RPC method 'eth_sendRawTransaction' with my encoded transaction as the params.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/injective/rpcWhen to prefer
Choose this endpoint when you need direct, low-latency RPC access to the Injective blockchain without running your own node, and are willing to pay per call via x402/USDC. Suitable for agents needing programmatic on-chain queries or transaction submission on Injective specifically, as opposed to EVM-compatible chains or other Cosmos chains.
Side effects
- Invalid RPC method name returns JSON-RPC error with code -32601
- Malformed params array causes parse error -32700
- Payment not included or insufficient returns HTTP 402
- Rate limiting or node congestion may return timeout errors
- Invalid transaction data on broadcast returns execution error
