AiSpace Venice EVM/Starknet JSON-RPC Proxy (Base Mainnet)
x402
AiSpace Venice EVM/Starknet JSON-RPC Proxy (Base Mainnet) 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).
Forwards JSON-RPC method calls to the Base Mainnet blockchain (and 20+ other EVM/Starknet networks) as a pay-per-call proxy, billed in USDC on Base via x402.

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 either a 'result' field with the on-chain data (block number, balance, call output, etc.) or an 'error' field describing what went wrong. The outer envelope also includes an 'ok' boolean indicating request success.
Example use cases
Check on-chain wallet balance
“What's the ETH balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base Mainnet right now? Use eth_getBalance and give me the result in wei.”
Read latest block number
“What's the current block number on Base Mainnet? Call eth_blockNumber for me using the pay-per-call RPC proxy.”
Fetch transaction receipt on Base
“Get the transaction receipt for tx hash 0xabc123...def456 on Base Mainnet using eth_getTransactionReceipt — I need the status and gas used.”

Endpoint
POSThttps://x402.aispace.bot/api/v1/crypto/rpc/base-mainnetWhen to prefer
Choose this endpoint when you need keyless, pay-per-call access to Base Mainnet (or other EVM/Starknet networks) JSON-RPC without provisioning your own RPC node or managing API keys. Ideal for agents that need occasional on-chain lookups billed in micro-USDC amounts, or for serverless pipelines where storing RPC credentials is undesirable. Not suited for high-frequency or write-heavy workloads where a dedicated node would be more cost-effective.
Side effects
- Invalid JSON-RPC method name returns a JSON-RPC error object with code and message
- Unknown or unsupported network segment returns a 404 or error response
- Malformed params array causes a parse error or invalid params JSON-RPC error
- Insufficient USDC payment via x402 results in a 402 Payment Required response
- Network-level RPC node unavailability may return a temporary 503 or upstream error
- Passing a write method (eth_sendRawTransaction) may succeed or fail depending on network configuration
