Output
A list of NFTs owned by the specified wallet address on BNB Chain, including token IDs, contract addresses, and metadata where available, plus a pagination key for fetching subsequent pages.
Example use cases
NFT portfolio audit for BNB wallet
“I need to see every NFT held by the wallet 0xAbC123...def on BNB Chain — fetch them all, up to 100 at a time.”
Verify NFT ownership before airdrop
“Before I send this airdrop, check whether wallet 0x9F3a...44b actually owns any NFTs on BNB Chain.”
Paginate through large NFT collection
“That wallet has a lot of NFTs on BSC — start fetching from the last page key 'page_abc123' and grab the next 25.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/bnb/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate all NFTs held by a specific wallet on the BNB (Binance Smart Chain) network. Prefer it over Ethereum or Polygon equivalents when the user's wallet or NFT collection is specifically on BSC/BNB Chain. Good for portfolio display, airdrop verification, or ownership checks.
Side effects
- Invalid or malformed owner wallet address returns an error
- Empty result set if wallet owns no NFTs on BNB Chain
- Rate limiting or payment failure if x402 payment is not properly attached
- pageKey mismatch or expiry leading to pagination errors
- Network timeout on BNB Chain RPC node
