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 list of NFTs owned by the specified Polygon wallet address, including token metadata (name, contract, token ID, image, etc.) and a pagination key for fetching subsequent pages when the owner holds more NFTs than the requested limit.
Example use cases
NFT portfolio audit for a wallet
“Show me all the NFTs held by Polygon address 0x1234abcd... — I want to see everything they own, up to 100 items.”
Verify NFT ownership before access
“Check whether Polygon wallet 0xDeAdBeEf... owns any NFTs right now — I need to verify they hold at least one before granting them access.”
Paginated NFT gallery feed
“Fetch the next page of NFTs for Polygon wallet 0x9999aaaa... using page key 'abc-page-key-xyz', limit 25 results.”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/polygon/nft/by-ownerWhen to prefer
Use this endpoint when you need to enumerate NFTs owned by a specific wallet on the Polygon network specifically, with pay-per-call pricing via x402 and no subscription required. Prefer this over general-purpose NFT APIs when you need lightweight, fast Polygon NFT lookups without setting up API key credentials.
Side effects
- Invalid or malformed owner wallet address returns an error
- Polygon network congestion may cause timeouts or slow responses
- Invalid pageKey causes pagination failure or empty results
- Limit value out of acceptable range may be rejected
- Payment failure via x402 prevents the call from being processed
