How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response from Infura's Base mainnet JSON-RPC node is passed through transparently — including JSON-RPC result fields, block data, transaction receipts, account balances, or error objects — after successful $0.01 USDC micropayment via the x402 protocol.
Example use cases
Check DeFi wallet balance on Base
“Look up the ETH balance of wallet 0x1234abcd... on Base mainnet using Infura — I need the latest balance and I'm fine paying the per-call fee.”
Fetch latest Base block number
“Get the current block number on the Base mainnet from Infura right now — just call eth_blockNumber and return the result.”
Read smart contract state on Base
“Call eth_call on the Base mainnet contract at 0xDeFi5678... with the encoded getReserves() function data so I can check current liquidity pool reserves.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/infura-base-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to Base mainnet JSON-RPC without committing to a monthly Infura subscription — ideal for low-frequency agent tasks, one-off blockchain queries, or DeFi workflows that need micropayment-native billing via x402 on Base L2.
Side effects
- Payment failure: insufficient USDC balance causes 402 Payment Required before request is forwarded
- Invalid JSON-RPC method: upstream returns a JSON-RPC error object with code and message
- Network congestion: upstream Infura latency spike or timeout
- Malformed path or body: gateway may reject or misroute the request
- Rate limiting: Infura upstream quota exceeded returns 429 or JSON-RPC error
