How this service works
Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.
Output
Returns a JSON object mapping token contract addresses to their respective balance values for the queried wallet address on the specified network. Supports pagination via pageKey and optional filtering to specific token contracts.
Example use cases
Example prompt
“What ERC-20 tokens does the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 hold on eth-mainnet? Just fetch all token balances for that address.”
Technical details
Endpoint
POSThttps://stablecrypto.dev/api/alchemy/token/token-balancesWhen to prefer
Use this endpoint when you need raw token balance data for a specific address on a specific EVM network (e.g. eth-mainnet, base-mainnet) with optional filtering by specific token contracts. Prefer this over the portfolio token balances endpoint (Tokens) when you need lower-level balance data without USD value enrichment, or when you want to check specific contract addresses only.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported or misspelled network slug causes failure
- Providing invalid token contract addresses in tokenAddresses returns empty or error results
- Pagination key mismatch or expiry causes pagination to fail
- Rate limiting or upstream Alchemy outage may cause 5xx errors
- Missing required fields (address or network) results in validation error
