Game inventory check on SEI
“Check what in-game NFT items are held by the SEI wallet sei1gamer8z0q2w4e6r8t1y3u5 so we can display their inventory in the app.”

Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sei/nft/by-ownerWhen to prefer
Use this endpoint when you specifically need NFT ownership data on the SEI blockchain. It is ideal for wallet portfolio lookups, airdrop eligibility checks, game inventory reads, or any agent workflow that needs to enumerate NFTs held by a given SEI address. Prefer this over generic NFT APIs if your target chain is SEI, as it provides SEI-native on-chain data at a low per-call cost via x402 micropayments.
Side effects
- Invalid or malformed SEI wallet address returns an error or empty result
- Non-existent address returns an empty NFT list
- Expired or invalid pageKey causes pagination errors
- Rate limiting or payment failure (402) blocks the request
- SEI network node unavailability causes timeout or 5xx error
