How this service works
Keyless attested data for autonomous agents. USDC on Base via x402. Official @x402/* middleware.
Output
A JSON-RPC response object containing the result of the requested method call (e.g. current block number as a hex string, account balance, transaction receipt, or other on-chain data), along with asset_id 'LION' and a resolved flag.
Example use cases
Check latest Base block number
“What's the current block number on Base? Use eth_blockNumber with no params.”
Fetch wallet ETH balance on Base
“Get the ETH balance for wallet address 0xAbC123... on Base — use eth_getBalance with block tag 'latest'.”
Query gas price on Ethereum
“What's the current gas price on Ethereum mainnet? Call eth_gasPrice with no params on the ethereum chain.”
Technical details
Endpoint
GEThttps://lion-x402-bible.lionmaster-operations.workers.dev/api/x402/keyless-base-rpc-jsonWhen to prefer
Choose this endpoint when an AI agent needs to make arbitrary JSON-RPC calls to Base or Ethereum without managing API keys or signing up for a node provider. It is particularly useful in autonomous agent workflows that support x402 micropayments (USDC on Base) and need keyless, attested blockchain data access on demand.
Side effects
- Invalid or unsupported JSON-RPC method returns an error response
- Malformed params JSON array causes a parse error
- Payment not fulfilled (x402 402 response) if USDC payment on Base fails
- Unsupported chain value (not 'base' or 'ethereum') may return an error
- Rate limiting or worker timeout for heavy RPC queries
