How this service works

Example use cases

Technical details
Endpoint
GEThttps://x402.silverbackdefi.app/api/v1/wallet-portfolioWhen to prefer
Use this endpoint when you need a comprehensive, USD-valued snapshot of all ERC-20 tokens in a wallet, especially on Base chain. Prefer this over individual token balance lookups when you need a full portfolio view in one call.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain ID returns an error or empty result
- Wallet with no ERC-20 holdings returns an empty portfolio
- Network timeout or provider unavailability causes a 5xx response
- Rate limiting or payment failure (x402) blocks the request
