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 Alchemy's Sui testnet RPC, passed through as-is including the original content-type header. Typically a JSON-RPC response object with result or error fields matching the Sui RPC specification.
Example use cases
Fetch latest Sui testnet checkpoint
“Hit the Alchemy Sui testnet RPC and get me the latest checkpoint sequence number — use the sui_getLatestCheckpointSequenceNumber method and handle the micropayment automatically.”
Inspect Sui testnet account balance
“I need to check the SUI coin balance for address 0xabc123 on the Sui testnet using Alchemy's RPC — call suix_getBalance with that address and pay per request.”
Submit Sui testnet transaction
“Send this signed transaction bytes to the Sui testnet via Alchemy's RPC using the sui_executeTransactionBlock method — forward the body I provide and settle the $0.01 USDC fee.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-sui-testnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use, no-API-key access to Alchemy's Sui testnet RPC via the x402 micropayment protocol. Ideal for agents that want to avoid managing long-lived API credentials and prefer on-demand microtransaction billing in USDC for testnet development and testing workflows.
Side effects
- Payment failure: insufficient USDC balance causes 402 response before the request is forwarded
- Invalid path: upstream returns 404 if the path below the Alchemy origin is malformed
- Upstream RPC error: Alchemy returns a JSON-RPC error if the method or params are invalid
- Rate limiting: Alchemy may throttle if the underlying API key is overloaded
- Malformed body: upstream returns 400 if the JSON body is not valid JSON-RPC
