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 Infura's Avalanche Mainnet node is passed through verbatim — typically a JSON-RPC response object containing the result field (e.g. balance in hex, block data, transaction receipt) or an error object if the call failed. Content-type mirrors the upstream response.
Example use cases
Check AVAX wallet balance on-chain
“What's the current AVAX balance for address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Avalanche mainnet? Use the Infura Avalanche gateway to call eth_getBalance at the latest block.”
Fetch latest Avalanche block number
“What's the latest block number on Avalanche mainnet right now? Query the Infura Avalanche endpoint using eth_blockNumber.”
Retrieve Avalanche transaction receipt
“Can you pull the transaction receipt for tx hash 0xabc123def456... on Avalanche mainnet via the Infura gateway using eth_getTransactionReceipt?”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/infura-avalanche-mainnetWhen to prefer
Choose this endpoint when you need pay-as-you-go, microtransaction-priced access to Infura's Avalanche Mainnet node without managing an API key subscription. It is ideal for agents that make infrequent or unpredictable calls to Avalanche and want to pay $0.01 USDC per call via the x402 protocol rather than maintaining a monthly Infura plan. Prefer it over direct Infura access when you need x402 payment flow integration in a web3-native agent architecture.
Side effects
- Payment failure: insufficient USDC balance causes 402 response before the upstream call is made
- Invalid JSON-RPC method: upstream returns a JSON-RPC error with code -32601 if the method doesn't exist
- Malformed body: if the forwarded body is not valid JSON, Infura returns a parse error
- Rate limiting: Infura project limits may cause 429 errors if the upstream quota is exceeded
- Network timeout: Avalanche node may be temporarily unreachable, returning a 504 or empty response
- Wrong path: an incorrect path below the origin results in a 404 from the upstream
