How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response body from the Alchemy Sui mainnet API, passed through transparently after the x402 micropayment is settled. The content type mirrors whatever Alchemy returns (typically JSON with blockchain data such as balances, transactions, objects, or RPC results).
Example use cases
Fetch Sui wallet balance on mainnet
“Check the SUI token balance for address 0x1234abcd on the Sui mainnet using Alchemy — I need the current balance in MIST.”
Query Sui transaction details
“Pull the details of Sui mainnet transaction digest ABC123XYZ from Alchemy so I can confirm it was finalized and get the gas used.”
Look up Sui NFT object state
“Fetch the on-chain state of Sui object ID 0xdeadbeef on mainnet from Alchemy — I need the current owner and object type fields.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-sui-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's Sui mainnet API without managing a long-term Alchemy subscription or API key — ideal for agents that make infrequent or variable-volume Sui blockchain queries and want to pay only for what they use via x402 USDC micropayments.
Side effects
- Payment failure: insufficient USDC balance causes 402 Payment Required before the request is forwarded
- Invalid path: unrecognized upstream path returns an error from Alchemy or a gateway 404
- Malformed body: invalid JSON in the body field causes upstream RPC errors
- Alchemy upstream downtime: gateway may return 502/503 if Alchemy Sui mainnet is unavailable
- Rate limiting: high call frequency may trigger upstream throttling from Alchemy
