Example use cases

Technical details
Endpoint
POSThttps://stablecrypto.dev/api/alchemy/portfolio/token-balancesWhen to prefer
Use this endpoint when you need EVM-compatible token portfolio data (ERC-20 balances) for one or more addresses on a specific network like Ethereum mainnet or Base, especially when Alchemy's portfolio API is the underlying data source. Prefer over generic RPC calls when you want enriched metadata and price data in a single call.
Side effects
- Invalid network slug returns error or empty result
- Malformed or non-checksummed wallet address may fail
- Empty addresses array may return error
- Network congestion may cause timeout
- Unsupported network slug returns error
- Rate limiting if called in high frequency
