AiSpace Venice EVM/Starknet JSON-RPC Proxy (Base Network)
x402
AiSpace Venice EVM/Starknet JSON-RPC Proxy (Base Network) is a paid API for AI agents from x402.aispace.bot, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Proxies JSON-RPC calls to the Base mainnet (and 20+ other EVM/Starknet networks) via a pay-per-call USDC micropayment on Base, requiring no API key.

How this service works
Pay-per-call JSON-RPC proxy to 20+ EVM and Starknet networks on Venice, paid per request in USDC on Base via x402, no API key. Resolve the {network} path segment from GET /api/v1/crypto/rpc/networks.
Output
A standard JSON-RPC response object containing the result field (block data, balance in hex wei, transaction receipt, contract return value, etc.) or an error object with code and message if the call fails.
Example use cases
Live wallet balance check on Base
“What's the current ETH balance for address 0x742d35Cc6634C0532925a3b8D4C9b3e5F1A2b3c4 on Base mainnet — fetch it from the chain right now.”
Read smart contract state
“Call the totalSupply function (eth_call) on the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base mainnet and return the result.”
Broadcast signed transaction
“I have a signed raw transaction hex — can you submit it to Base mainnet using eth_sendRawTransaction and give me the transaction hash?”
Technical details
Endpoint
POSThttps://x402.aispace.bot/api/v1/crypto/rpc/baseWhen to prefer
Choose this endpoint when you need trustless, keyless EVM or Starknet JSON-RPC access and want to pay per call in USDC on Base without managing API keys or subscriptions. Ideal for agents that make infrequent or bursty blockchain queries across multiple networks and want micropayment-based cost control. Prefer over managed node providers (Alchemy, Infura) when avoiding credential management is a priority.
Side effects
- Invalid JSON-RPC method name returns a JSON-RPC error object with code -32601
- Malformed params array causes a -32602 invalid params error
- Insufficient USDC payment via x402 results in a 402 Payment Required HTTP response
- Unknown or unsupported network segment returns a 404 or routing error
- Network node timeout or downtime returns a -32603 internal error
- Attempting a write method (eth_sendRawTransaction) with an unsigned or invalid tx hex returns a revert or nonce error
