Example prompt: Can you show me the NFT collections held by Base wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to see the names, how many of each, and the floor prices, with spam filtered out?

## When to prefer this

Choose this endpoint when you need a clean, spam-filtered view of NFT holdings for a Base wallet, especially when floor value context is needed alongside collection names and counts. Prefer it over raw blockchain queries or non-spam-filtered NFT APIs when building wallet profiles or portfolio summaries on Base.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Non-Base (e.g. Ethereum mainnet) addresses may return empty or incorrect results
- Wallet with no NFTs returns an empty collection list
- Covalent API downtime may cause upstream failures
- Rate limiting or payment failure ($0.01 USDC) may block the request

## How this service works

## Output

A spam-filtered list of NFT collections held by the specified Base wallet, each with collection name, token count, and floor value in USD — suitable for profiling a wallet's NFT exposure.
