How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a paginated list of NFTs owned by the specified Avalanche wallet address, including token IDs, contract addresses, metadata, and a pageKey for fetching the next page of results.
Example use cases
NFT portfolio audit for a wallet
“I want to see every NFT currently held in Avalanche wallet 0xDe45F...abc — give me the full list, up to 100 items.”
Gating check for NFT-based access
“Check whether the Avalanche wallet 0x7fA1...C3b holds any NFTs from our drop — I need to verify ownership before granting access.”
Paginating through a large NFT collection
“The Avalanche wallet 0xBb29...11e has a huge collection — start fetching its NFTs with a limit of 20 and give me a page key so I can continue browsing.”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/avalanche/nft/by-ownerWhen to prefer
Use this endpoint when you need on-chain NFT ownership data specifically on the Avalanche network, with pay-per-call pricing via x402 (no API key subscription needed). Prefer it over self-hosted RPC calls when you want a managed, low-latency abstraction that handles indexing across 57+ networks and returns structured NFT metadata without raw RPC parsing.
Side effects
- Invalid or malformed wallet address returns a 400 or empty result
- Wallet with no NFTs returns an empty list
- Expired or invalid pageKey breaks pagination and may return an error
- Rate limiting or quota exceeded on the pay-per-call plan
- Network timeout on slow Avalanche RPC nodes
- Payment not processed (x402) results in 402 response blocking the call
