How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

Output

Returns a JSON object containing a data field with the resource ID, resource type, and attributes describing the wallet's NFT portfolio (collections, counts, and metadata), plus pagination/self links.

Example use cases

Whale wallet NFT audit

“Look up the NFT portfolio for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me what collections they hold and how many NFTs total.”

Solana collector portfolio check

“What NFTs does the Solana wallet 5FHwkrdxkjyYyMoEMHnFxbCQJvgRqZvFJhvDvGEbHnHT hold right now?”

Multi-chain NFT inventory for a user

“Give me a summary of all the NFTs owned by the wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — I want to see everything across every chain Zerion tracks.”

Technical details

Endpoint

GEThttps://api.zerion.io/v1/wallets/%7Baddress%7D/nft-portfolio?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a consolidated NFT portfolio view for a specific wallet across 40+ EVM chains and Solana in a single call. Prefer this over on-chain RPC calls when you want interpreted, aggregated data without chain-by-chain querying. Best suited for agents that need to quickly summarize a wallet's NFT holdings without managing multi-chain infrastructure.

Side effects

Invalid or malformed wallet address returns a 400 or empty data response
Wallet address with no NFTs returns empty data array
Unsupported chain or address format may return error or empty result
Payment not provided or insufficient USDC balance causes x402 payment required error
Rate limiting may cause temporary 429 errors
Network timeouts on heavily loaded wallets with many NFTs
