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 World Chain Mainnet node are passed through transparently after the x402 micropayment of $0.01 USDC is verified — including JSON-RPC result objects, error messages, or any other data the Alchemy endpoint returns.
Example use cases
Fetch latest World Chain block
“Get the latest block from World Chain Mainnet using the Alchemy RPC — call eth_getBlockByNumber with 'latest' and return the full block details.”
Check on-chain account balance
“Look up the World Chain Mainnet balance for wallet address 0xAbC123... using the Alchemy node — send an eth_getBalance call for that address at the latest block.”
Retrieve transaction receipt on World Chain
“Fetch the transaction receipt for tx hash 0xDef456... on World Chain Mainnet through the Alchemy gateway and tell me whether it succeeded or failed.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-worldchain-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use, no-subscription access to the Alchemy World Chain Mainnet node and want to pay micropayments in USDC via the x402 protocol rather than managing an Alchemy API key or subscription. Ideal for agents and automation workflows that make sporadic or low-volume World Chain RPC calls and want cost-efficient, permissionless access.
Side effects
- Payment failure: x402 payment not provided or insufficient USDC balance causes request to be rejected before forwarding
- Invalid path: malformed or unrecognized path parameter results in upstream 404 or routing error
- Alchemy upstream error: World Chain Mainnet node returns RPC error (e.g. invalid method, malformed params) passed through as-is
- Rate limiting: Alchemy upstream rate limits triggered if too many requests are sent in rapid succession
- Network timeout: upstream Alchemy node unreachable or slow, resulting in gateway timeout
