How this service works
60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.
Output
A JSON object containing a 'native' field with the ETH balance in ether, and a 'tokens' array where each entry has the human-readable decimal-adjusted amount and the token symbol — ready to display or process without further conversion.
Example use cases
DeFi dashboard portfolio snapshot
“Show me the current ETH balance and USDC and DAI token balances for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet, with the amounts already formatted to human-readable decimals.”
Pre-trade liquidity check
“Before I submit this swap, can you check how much ETH and USDC the wallet 0xAbCd...1234 holds on Base right now so I know if there's enough to cover the trade?”
Multi-token balance audit
“I need to audit wallet 0x742d35Cc6634C0532925a3b8D4C9E8d02aB9D8e on Arbitrum — grab the native ETH balance plus WBTC (0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f) and USDT (0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9) all in one shot.”
Technical details
Endpoint
POSThttps://flat-rate-llm.kikoribera03.workers.dev/v1/evm/portfolioWhen to prefer
Use this endpoint when you need native balance plus multiple ERC20 token balances for a single wallet on one EVM chain in a single round-trip — it saves you from making one eth_getBalance call plus N separate eth_call calls and manually applying decimals. Prefer this over raw contract calls or individual balance checks when building portfolio views, pre-trade liquidity checks, or wallet audits where batch efficiency matters.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported chain identifier causes a chain-not-found error
- Invalid token contract address (e.g. not an ERC20) may return zero or cause a revert
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network congestion on the target chain may cause timeouts
- Token with non-standard decimals implementation may return unexpected amounts
