Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/eth-optimism/%7B*path%7D/*When to prefer
Use this endpoint when an AI agent needs to query Optimism (OP Mainnet) blockchain state — contract calls, balances, transactions, blocks — without managing its own RPC node infrastructure, and is willing to pay per call via x402/USDC micropayment.
Side effects
- Invalid JSON-RPC method returns RPC error object
- Insufficient USDC payment results in 402 Payment Required
- Malformed request body returns 400 Bad Request
- Optimism node unavailable returns 503 or gateway error
- Invalid address format causes RPC parse error
