> Zerion Wallet NFT Positions is a paid API for AI agents from api.zerion.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-03).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability zerion-wallet-nft-positions-cf8522fc
```

Example prompt: Can you pull up all the NFTs held by wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e across all supported chains using Zerion?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-chain NFT inventory for a specific wallet address, especially when you want interpreted and structured NFT position data (not raw on-chain logs). Prefer Zerion's NFT positions endpoint over direct blockchain RPC calls when you need cross-chain aggregation across 40+ EVM networks and Solana without managing individual chain connections yourself.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain or address format not recognized
- Wallet with no NFTs returns an empty data array
- Rate limiting or payment failure (x402) if the $0.01 USDC per-call fee is not satisfied
- Network timeout for wallets with very large NFT holdings requiring paginated fetches

## Output

An array of JSON:API resource objects, each representing an NFT position in the wallet. Each item includes a resource ID, resource type, and an attributes object with NFT details (as documented at developers.zerion.io), along with pagination links for navigating large result sets.
