How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw JSON-RPC response body from Infura's BSC Mainnet node, passed through transparently — including fields like result, id, jsonrpc, and any error object if the call fails. Response content type mirrors the upstream.
Example use cases
Check BNB wallet balance on-chain
“Look up the current BNB balance on BSC mainnet for wallet 0xDe0B295669a9FD93d5F28D9Ec85E40f4cb697BAe using eth_getBalance with the latest block.”
Fetch BSC transaction receipt
“Get the transaction receipt for BSC mainnet tx hash 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 so I can confirm it was mined.”
Read smart contract state via eth_call
“Call the balanceOf function on BSC mainnet smart contract 0x55d398326f99059fF775485246999027B3197955 for address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B to check the USDT token balance.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/infura-bsc-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use access to Infura's BSC Mainnet JSON-RPC without managing an Infura API key subscription — ideal for agents making infrequent or unpredictable BSC queries where a $0.01/call model is more cost-efficient than a monthly plan. Prefer over raw Infura direct access when operating in an x402-native payment context.
Side effects
- Payment failure: x402 micropayment of $0.01 USDC not fulfilled, request blocked before proxying
- Invalid JSON-RPC method: upstream returns a JSON error object with code -32601
- Malformed request body: gateway may reject or upstream returns parse error
- BSC node unavailable: Infura outage causes 502/503 upstream error
- Rate limit exceeded on upstream Infura endpoint
- Invalid wallet address or transaction hash returns empty or null result
