Output

Example use cases
NFT portfolio audit for a SEI wallet
“Can you pull up all the NFTs owned by SEI wallet sei1qpzry9x8gf2tvdw0s3jn54khce6mua7l and show me what they're holding? Limit to 25 results.”
Verify NFT ownership before a trade
“Before I proceed with this deal, can you check whether the SEI wallet sei1ht3ahljytf6rqpmlv9zvpqhqd5zs3fzvp6nh5x actually owns the NFT in question? Fetch all their NFTs from the SEI network.”
Paginate through large NFT collection
“That SEI wallet has tons of NFTs — can you continue fetching the next page of their holdings using page key 'abc789pagetoken' with a limit of 50?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/sei/nft/by-owner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to enumerate NFT holdings of a wallet address on the SEI blockchain. Prefer this over generic multi-chain NFT APIs when you know the target chain is SEI and want fast, pay-per-call pricing without subscriptions.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent wallet returns empty NFT list
- Invalid pageKey causes pagination failure
- Rate limiting or payment failure (x402) blocks the request
- SEI network downtime or RPC errors cause lookup failure
