Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/arbitrum/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate NFT holdings for a specific wallet address specifically on the Arbitrum L2 network. Prefer this over Ethereum mainnet NFT endpoints when your use case is Arbitrum-native assets. Ideal for portfolio displays, NFT-gated access checks, and collector analytics on Arbitrum.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent or zero-NFT wallet returns an empty list
- Rate limiting or payment failure (x402) blocks the call
- Invalid pageKey causes pagination to fail or reset
- Network timeout if Arbitrum indexer is slow to respond
