How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a list of NFTs owned by the specified wallet address on the Abstract network, including token identifiers and metadata, along with a pagination key (pageKey) for retrieving subsequent pages of results.
Example use cases
NFT portfolio audit for a wallet
“Show me all the NFTs held by wallet 0x1234...abcd on the Abstract network — give me up to 50 at a time.”
Collector discovery for a marketplace
“I need to see which NFTs wallet 0xABCD...9876 owns on Abstract so I can personalize their marketplace experience — pull the first 25.”
Paginating through large NFT holdings
“I already have a pageKey from a previous query — can you fetch the next batch of NFTs owned by 0xDEAD...BEEF on Abstract using that key, limit 30?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/abstract/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate NFTs held by a specific wallet specifically on the Abstract (L2) blockchain network. It supports pagination via pageKey and limit, making it suitable for wallets with large NFT holdings. Prefer this over generic NFT APIs if your use case is specifically Abstract-chain NFT ownership data.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Expired or invalid pageKey causes pagination to fail
- Network or RPC errors from the Abstract chain provider
- Rate limiting if too many calls are made in rapid succession
- Empty result if the wallet holds no NFTs on Abstract
