## When to prefer this

Choose this endpoint when you need on-chain NFT portfolio data for a specific wallet address across Base, Arbitrum, or Solana and want a pay-per-call model via x402 micropayments without a subscription. Prefer it over general blockchain explorers when you need structured, agent-ready JSON output specifically for NFT holdings.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address with no NFT holdings may return empty portfolio array
- Unsupported chain address formats may result in no results
- Network timeouts or upstream indexer failures may cause delayed or failed responses
- Rate limiting or payment failure via x402 micropayment may block access
