Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/eth-arbitrum/%7B*path%7DWhen to prefer
Use this endpoint when you need metered, pay-per-call access to the Arbitrum L2 network without managing your own RPC API keys or node infrastructure. Ideal for AI agents operating with x402 micropayment wallets that need occasional Arbitrum blockchain reads or writes without committing to a subscription RPC provider.
Side effects
- Payment not included or insufficient USDC balance — 402 Payment Required
- Invalid JSON-RPC method or malformed params — returns JSON-RPC error code -32601 or -32602
- Network congestion causing RPC timeout — 504 Gateway Timeout
- Invalid Ethereum address or transaction hash — RPC error with descriptive message
- Rate limiting or gateway capacity exceeded — 429 Too Many Requests
