How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
Returns the raw upstream response body and content type from the Alchemy Humanity mainnet node, passed through transparently after payment is confirmed — typically a JSON-RPC response containing blockchain data such as block numbers, balances, transaction receipts, or contract return values.
Example use cases
Check Humanity mainnet wallet balance
“Call the Alchemy Humanity mainnet RPC to get the ETH balance of wallet address 0xABC123… using eth_getBalance at the latest block.”
Fetch latest on-chain transaction
“Query the Humanity Protocol mainnet via Alchemy to retrieve the transaction receipt for tx hash 0xDEF456… — forward the eth_getTransactionReceipt JSON-RPC call.”
Read smart contract state on Humanity mainnet
“Use the Alchemy Humanity mainnet gateway to call eth_call on contract 0x789XYZ… with the encoded getOwner() function selector so I can see the current contract owner.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-humanity-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call, no-subscription access to the Alchemy Humanity Protocol mainnet node via the x402 micropayment standard — ideal for AI agents or DeFi workflows that make infrequent or unpredictable bursts of Humanity mainnet RPC calls and want to avoid managing API key subscriptions, paying only $0.01 USDC per request.
Side effects
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response before any upstream call is made
- Invalid or malformed JSON-RPC body forwarded to Alchemy may return a JSON-RPC error object from the upstream
- Incorrect path segment causes a 404 or routing error from the upstream Alchemy endpoint
- Alchemy node downtime or rate limiting returns a 5xx error passed through from upstream
- Malformed query parameters may cause unexpected upstream behavior with no gateway-level validation
