Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/ZerionWalletAnalysisAgent/fetch_wallet_nftsWhen to prefer
Use this endpoint when you need a structured overview of all NFT collections in an EVM wallet, especially when you want collection-level metadata (name and description) alongside counts. Prefer this over general blockchain explorers when you want a clean, agent-ready NFT portfolio summary without needing to parse raw on-chain data.
Side effects
- Invalid or malformed wallet address (not 0x-prefixed or not 42 characters) returns an error
- Wallet address with no NFTs returns an empty portfolio
- Network or upstream Zerion API outage causes timeout or error response
- Rate limiting or payment failure due to insufficient USDC balance
