How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Infura Unichain mainnet RPC response body, passed through transparently after the x402 micropayment is processed. Returns standard Ethereum JSON-RPC response objects including result fields, block data, transaction receipts, or error objects depending on the method called.
Example use cases
Check Unichain wallet balance
“Look up the ETH balance for wallet address 0xAbC123... on Unichain mainnet right now.”
Fetch Unichain transaction receipt
“Get the transaction receipt for tx hash 0xDef456... on Unichain mainnet and tell me if it succeeded.”
Read Unichain smart contract state
“Call the balanceOf function on Unichain mainnet smart contract 0x789... for address 0xAbC123... and return the result.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/infura-unichain-mainnetWhen to prefer
Choose this endpoint when you need pay-per-call access to Unichain mainnet JSON-RPC without managing an Infura API key subscription, and your agent environment supports the x402 micropayment protocol for automatic per-request USDC billing. Ideal for low-volume or sporadic Unichain queries where a subscription is wasteful.
Side effects
- Insufficient USDC balance to cover $0.01 per-call fee — payment rejected before request is forwarded
- Invalid or malformed JSON-RPC body — upstream returns a JSON-RPC error object
- Unsupported RPC method for Unichain — upstream returns method-not-found error
- Network or Infura upstream outage — 502/503 passthrough error
- Invalid path parameter — gateway cannot route to upstream correctly
- x402 facilitator unavailable — payment verification fails and request is blocked
