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 JSON-RPC response object containing the result field with blockchain data (account resources, transaction details, ledger info, etc.) or an error object with code and message if the call fails.
Example use cases
Check Aptos account balance
“Look up the APT coin balance for Aptos address 0xabc123... using the blockchain RPC and tell me how much APT they hold.”
Fetch Aptos transaction status
“I just submitted an Aptos transaction with hash 0xdeadbeef... — can you check the RPC to see if it confirmed yet and what the status is?”
Read Move smart contract resource
“Query the Aptos RPC for the 0x1::coin::CoinStore resource on account address 0x99abc... so I can see the token holdings stored in that Move module.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/aptos/rpcWhen to prefer
Choose this endpoint when you need pay-per-call access to the Aptos blockchain RPC without managing your own node or API key subscriptions. It is well-suited for agents that interact with Aptos infrequently or need quick integration with the Aptos network through a standardized JSON-RPC interface paid via USDC microtransactions.
Side effects
- Invalid RPC method name returns error with unknown method message
- Malformed params array causes parse or invalid params error
- Non-existent account address returns resource not found error
- Network congestion or Aptos node downtime causes timeout or service unavailable
- Payment failure via x402 blocks the request before it reaches the RPC layer
