How this service works
Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.
Output
Returns the native token balance (in wei or ETH) for each of the queried addresses on the specified EVM chain, keyed by address.
Example use cases
Example prompt
“Can you look up the ETH balances on Ethereum mainnet (chain ID 1) for these three wallet addresses: 0xAbc...1, 0xDef...2, and 0x123...3?”
Technical details
Endpoint
POSThttps://stablecrypto.dev/api/etherscan/account/balance-multiWhen to prefer
Use this endpoint when you need to check native ETH (or EVM-compatible chain native token) balances for multiple addresses (up to 20) in a single request, rather than making individual balance calls. Ideal for portfolio aggregation, wallet monitoring dashboards, or any workflow that needs to batch balance lookups efficiently across Ethereum, Polygon, Base, or other EVM chains.
Side effects
- More than 20 addresses provided — API rejects the request
- Invalid or malformed address in the comma-separated list
- Unsupported chain ID — chain not indexed by the provider
- Network timeout or upstream Etherscan API unavailability
- Missing required fields (chainid or address) return validation error
