Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/kaia/nft/salesWhen to prefer
Use this endpoint when you specifically need NFT sales data on the Kaia blockchain (formerly Klaytn) and need fine-grained block-range filtering. Prefer this over general NFT APIs when you need pay-per-call pricing without subscription commitment, or when Kaia network coverage is required and your primary NFT data provider does not support it.
Side effects
- Invalid contract address format returns an error
- fromBlock greater than toBlock yields empty or error response
- Limit value out of acceptable range may be rejected
- Block range spanning too many blocks may time out or be truncated
- Payment failure (x402) blocks the request entirely
- Network unavailability for Kaia RPC returns upstream error
