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 the Alchemy XLayer Mainnet API is passed through directly, including the response body and content type — typically a JSON-RPC result object containing blockchain data, transaction receipts, or error details.
Example use cases
Fetch XLayer account token balance
“Query the XLayer mainnet for the ERC-20 token balance of wallet address 0xABC...123 using the Alchemy API — send the eth_call to the token contract at path /v2.”
Submit XLayer mainnet transaction
“Broadcast a signed raw transaction to the XLayer mainnet via Alchemy — forward it as an eth_sendRawTransaction JSON-RPC call with the signed tx hex in the body.”
Read XLayer smart contract state
“Call the read-only 'totalSupply' function on XLayer mainnet smart contract 0xDEF...456 through the Alchemy XLayer gateway using eth_call at path /v2.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-xlayer-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's XLayer Mainnet RPC without managing a subscription or API key — ideal for agents making occasional or unpredictable numbers of XLayer blockchain queries where a flat subscription is wasteful. Prefer this over direct Alchemy subscriptions for serverless or agent-driven workloads billed via x402 USDC micropayments.
Side effects
- Payment failure: insufficient USDC balance causes x402 payment rejection before request is forwarded
- Upstream error: Alchemy XLayer returns RPC error (invalid method, bad params, reverted tx)
- Invalid path: unrecognized path below the upstream origin returns 404 or gateway error
- Malformed body: non-JSON or invalid JSON-RPC body forwarded upstream may return parse error
- Network timeout: XLayer mainnet or Alchemy infrastructure temporarily unreachable
