## When to prefer this

Use this endpoint when you need to enumerate all NFT collections held by a specific wallet address across 40+ EVM chains and Solana. Prefer this over generic NFT APIs when you need multi-chain aggregation in a single call, or when you need structured JSON:API formatted output compatible with Zerion's broader wallet data ecosystem. Ideal for portfolio dashboards, wallet analytics tools, or any agent workflow that needs to inventory a user's NFT holdings without querying individual chains separately.

## Known failure modes

- Invalid wallet address format returns an error or empty result
- Wallet address not found on any supported chain returns empty data array
- Rate limiting or payment failure returns 402 or 429 status
- Malformed query parameters result in 400 bad request
- Temporary Zerion API outage returns 500 or timeout

## Output

Returns a JSON:API-formatted array of NFT collection resource objects held by the specified wallet, each with an ID, type, and attributes describing the collection (such as name, floor price, and other metadata). Also includes pagination links for navigating large result sets.
