Example use cases
Crypto portfolio snapshot for a user
“Show me all the token holdings for wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B across Ethereum and Base, filtering out anything under $0.50 in value.”

On-chain due diligence on a wallet address

Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/wallet/portfolioWhen to prefer
Choose this endpoint when you need a quick, multi-chain EVM token portfolio snapshot for a specific wallet address, especially across Ethereum, Base, Arbitrum, and Optimism. It is well-suited for DeFi dashboards, on-chain due diligence, or agent workflows that need to assess wallet holdings without running a full blockchain node. At $0.005 per call, it is cost-effective for per-query lookups. Prefer alternatives if you need NFT holdings, historical balances, or chains beyond the supported EVM set.
Side effects
- Invalid or malformed wallet address returns an error
- Specifying more than 4 chains exceeds the maxItems constraint
- Unsupported chain names may return empty or error responses
- Payment failure via x402 results in 402 response with no data
- Wallet with no holdings returns an empty portfolio
- Network timeouts on specific chains may yield partial results
