POSThttps://phantom-api-omega.vercel.app/api/xlayer/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call RPC access to the X Layer (OKX Layer 2) network without managing node infrastructure or committing to a subscription. Ideal for agents that need occasional or unpredictable on-chain lookups on X Layer specifically, and want to pay only for what they use via USDC microtransactions.
Side effects
- Invalid RPC method name returns JSON-RPC error with code -32601
- Malformed params array causes parse error (-32700) or invalid params error (-32602)
- Network congestion or node unavailability may cause timeout or 503 response
- Insufficient x402 payment causes 402 Payment Required before RPC is executed
- Querying non-existent block or transaction hash returns null result
