Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/kaia/rpcWhen to prefer
Choose this endpoint when you need direct, low-latency RPC access to the Kaia (formerly Klaytn) blockchain specifically, and want pay-per-call pricing without a subscription. Ideal for agents that need occasional on-demand Kaia chain queries without committing to a dedicated node provider.
Side effects
- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Network congestion or node unavailability may cause timeouts
- Insufficient x402 payment results in 402 Payment Required response
- Querying non-existent block number or transaction hash returns null result
