How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream JSON-RPC response from Infura's Mantle mainnet node, passed through transparently after the x402 micropayment of $0.01 USDC is verified. Includes standard JSON-RPC fields such as result, id, and jsonrpc version.
Example use cases
Check Mantle wallet balance
“Look up the ETH balance of wallet address 0xAbC123... on Mantle mainnet using the Infura RPC — call eth_getBalance for the latest block.”
Fetch latest Mantle block
“Get the most recent block on the Mantle mainnet blockchain, including all transaction hashes, using eth_getBlockByNumber with the 'latest' tag.”
Read smart contract state
“Call the balanceOf function on the Mantle mainnet contract at 0xDEF456... for my address 0xAbC123... using eth_call so I can check my token holdings.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/infura-mantle-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to Infura's Mantle mainnet RPC without managing API keys or subscriptions, and you are already operating in an x402 micropayment context. Ideal for agents making sporadic or low-volume Mantle blockchain queries where a flat subscription is wasteful.
Side effects
- Payment failure: x402 payment not included or insufficient USDC balance causes 402 rejection
- Invalid path: malformed or unsupported RPC path returns upstream error
- Infura quota exceeded: upstream Infura rate limit or node error returns 5xx
- Invalid JSON body: malformed RPC body causes upstream parse error
- Network unavailability: Mantle mainnet congestion or Infura outage returns timeout or 503
