Example use cases
NFT portfolio audit for a wallet
“What NFTs does the wallet 0xAbC123...789 currently hold on opBNB? Show me up to 50 items.”
NFT-gated access verification
“Check if wallet 0xDEF456...012 owns any NFTs on opBNB — I need to verify they qualify for our token-gated content.”
Paginated NFT inventory browsing
“Get the next page of NFTs for wallet 0x9876...FEDC on opBNB using page key 'eyJhbGci...' and limit results to 25.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/opbnb/nft/by-ownerWhen to prefer
Use this endpoint when you specifically need to enumerate NFT holdings on the opBNB (BNB Layer 2) network for a given wallet. Prefer this over generic NFT APIs when opBNB chain data is required and pay-per-call micro-payment via x402 is acceptable. Good for one-off lookups or agent workflows that need programmatic NFT ownership checks without a subscription.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- opBNB node unavailability causes timeout or 5xx error
- Invalid pageKey causes pagination failure or unexpected results
- Missing required 'owner' field returns a validation error
- Rate limiting or payment failure via x402 may block the call
