How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Alchemy BNB Chain mainnet API response body is passed through after successful x402 micropayment verification — this includes standard JSON-RPC blockchain data such as block info, transaction receipts, account balances, contract call results, and other on-chain data in Alchemy's standard response format.
Example use cases
Check wallet token balance on BNB
“Fetch the BNB Chain mainnet token balance for wallet 0xABC123 using the Alchemy BNB mainnet node — call eth_getBalance at the root path.”
Read smart contract state on BSC
“Query the Alchemy BNB mainnet node to call eth_call on smart contract 0xDEF456 with the encoded getReserves() function data so I can see the current liquidity pool reserves.”
Look up recent transaction receipt
“Pull the transaction receipt for tx hash 0x789GHI on BNB Chain mainnet from the Alchemy node — use eth_getTransactionReceipt and return the full receipt data.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-bnb-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use access to Alchemy's BNB Chain mainnet node without managing Alchemy API keys or subscriptions. Ideal for agents that need sporadic or low-volume BNB Chain RPC calls billed via x402 USDC micropayments. Prefer this over self-managed Alchemy keys when cost predictability per call ($0.01 USDC) matters or when operating in a wallet-native agent environment. Not suitable for high-frequency or batch RPC workloads where a direct Alchemy subscription would be more economical.
Side effects
- Insufficient USDC balance or failed x402 payment — payment authorization rejected, request not forwarded
- Invalid or malformed JSON-RPC body — upstream Alchemy returns JSON-RPC error
- Unsupported RPC method — Alchemy may reject methods not available on BNB mainnet
- Incorrect path parameter — upstream routing fails with 404
- Alchemy rate limit or node unavailability — upstream 429 or 503 passed through
- Network timeout on BNB Chain node — slow or unresponsive upstream
