Example use cases
DeFi portfolio net worth check
“What's the current USD value of my wallet 0x1234abcd...5678 on Base, including my holdings in these two tokens: 0xTokenAddress1 and 0xTokenAddress2?”
Multi-token treasury valuation
“Can you value the DAO treasury wallet 0xDeadBeef...1234 on Arbitrum and include these five ERC-20 contract addresses so I know the full dollar amount of our holdings?”
Pre-trade position sizing
“Before I make a trade, tell me the total USD value of wallet 0xMyWallet...ABCD on Polygon — include USDC at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 so I can see my full balance.”
Technical details
Endpoint
POSThttps://crypto-portfolio-valuator.pdfextractapi.workers.dev/valuateWhen to prefer
Use this endpoint when you need a quick USD valuation of a single wallet's native and ERC-20 token holdings across major EVM chains. It supports Ethereum, Base, Polygon, Arbitrum, Optimism, and BNB chains. Prefer this over manual on-chain lookups or multi-step token price APIs when you need an aggregated dollar value in one call.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain key causes rejection — must be one of: ethereum, base, polygon, arbitrum, optimism, bnb
- More than 10 ERC-20 token addresses provided exceeds limit
- Invalid ERC-20 contract address may return zero value or error
- Network/RPC timeout for the specified chain
- Token price feed unavailable for obscure ERC-20 contracts
