How this service works
Portfolio API — multi-chain token balances and metadata for one or more wallet addresses (not chain-specific).
Output
A list of token holdings per wallet address, each entry including token name, symbol, contract address, chain, raw balance, decimals, and optionally USD-denominated value, aggregated across all supported EVM and non-EVM chains.
Example use cases
Example prompt
“What tokens does wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 currently hold across all chains — show me the balances and token symbols.”
Technical details
Endpoint
POSThttps://x402.alchemy.com/data/v1/assets/tokens/by-address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a unified, multi-chain view of fungible token holdings for one or more wallet addresses without specifying a particular chain. Prefer this over chain-specific RPC balance calls when you need cross-chain aggregation in a single request, or when you need token metadata (symbol, decimals, name) alongside raw balances. It is especially useful for portfolio dashboards, wallet analytics, and DeFi position summarization.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Unsupported chain silently omitted or returns empty results
- Payment not accepted or insufficient USDC balance causes 402 response
- Rate limiting or quota exceeded returns 429
- Wallet with no token balances returns empty array
- Network timeout on slow chains returns partial results
