Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/eth-arbitrum/%7B*path%7D/*When to prefer
Use this endpoint when you need programmatic access to the Arbitrum L2 network without managing your own RPC node, especially in pay-as-you-go agentic contexts where per-call micropayment billing (x402/USDC) is preferred over subscription-based RPC providers.
Side effects
- Invalid JSON-RPC method returns error response
- Malformed params cause parse error
- Insufficient x402 payment results in 402 Payment Required
- Network congestion causes timeout
- Invalid transaction data returns execution revert
- Unsupported Arbitrum-specific method returns method not found
