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 and content type from the Alchemy Monad mainnet API, passed through transparently after the x402 micropayment of $0.01 USDC is processed. The agent receives whatever the upstream RPC or data API returns for the given path, method, query, and body.
Example use cases
Check Monad wallet balance
“Look up the ETH balance of wallet address 0xAbC123... on Monad mainnet through the Alchemy gateway and tell me what it holds.”
Fetch latest Monad block data
“Get me the latest block details from Monad mainnet — number, timestamp, and transaction count — using the Alchemy RPC proxy.”
Call Monad smart contract read method
“Call the balanceOf method on the Monad mainnet contract at 0xDef456... for address 0xAbC123... and return the result.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-monad-mainnet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need pay-per-call access to Alchemy's Monad mainnet RPC or data APIs without managing an Alchemy API key directly, and your agent has a USDC wallet capable of x402 micropayments. Prefer this over a direct Alchemy subscription for low-frequency or cost-controlled agent usage on the Monad blockchain specifically.
Side effects
- Payment failure: insufficient USDC balance causes 402 Payment Required with no upstream call
- Invalid path: upstream returns 404 if the specified path does not exist on Alchemy Monad
- Malformed body: upstream returns 400 if the JSON body is invalid for the RPC method
- Upstream outage: Alchemy Monad service unavailable returns 502 or 503
- Rate limiting: Alchemy upstream may return 429 if downstream quota is exceeded
- Network timeout: vercel.app cold-start or upstream latency may cause timeouts
