How this service works
EVM wallet net worth on Ethereum, Base, Arbitrum, Optimism and Polygon: native coin plus about 40 major tokens (USDC, USDT, DAI, WETH, WBTC, cbBTC, stETH, LINK, ARB, OP and more), each balance priced with Chainlink oracle feeds, with per-chain and overall USD totals. Live on-chain reads, one Multicall3 per chain. Free sample: https://onchain-health.mick8511.workers.dev/sample
Output
A JSON object containing per-chain breakdowns (each with per-token balances and USD values using Chainlink oracle prices) plus an aggregated overall USD total. Each token entry includes balance, token symbol, price, and USD value. Native coins (ETH, MATIC, etc.) are included alongside ~40 major ERC-20 tokens such as USDC, USDT, DAI, WETH, WBTC, cbBTC, stETH, LINK, ARB, and OP.
Example use cases
Portfolio snapshot for a DeFi whale
“Can you tell me the total USD value of all crypto holdings in wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, including native coins and tokens like USDC, WETH, and WBTC, across Ethereum, Base, Arbitrum, Optimism, and Polygon?”
Single-chain wallet valuation on Base
“What's the current USD worth of the wallet 0xAbCd1234567890abcdef1234567890ABCDEF1234 on Base only — I just want to see the Base chain balances priced in USD.”
Automated treasury monitoring agent
“Every hour, check the net worth of our treasury wallet 0xFe89cc7aBB2C4183683ab71653C4cdc9B02D44db across Ethereum and Arbitrum and alert me if the total drops below $500,000.”
Technical details
Endpoint
POSThttps://onchain-health.mick8511.workers.dev/net-worth?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, live USD net worth for an EVM wallet spanning multiple chains (Ethereum, Base, Arbitrum, Optimism, Polygon) with Chainlink-verified prices. It is ideal for portfolio valuation, treasury monitoring, or any agent task requiring accurate cross-chain asset aggregation without managing separate RPC calls or oracle integrations. Prefer it over block explorer APIs when you need both multi-chain coverage and live Chainlink pricing in a single call.
Side effects
- Invalid or malformed EVM address (must match 0x[40 hex chars]) returns a validation error
- Unsupported chain name in the chains parameter returns an error
- On-chain RPC timeout or Multicall3 failure for a given chain may cause partial or error response
- Stale or unavailable Chainlink feed may affect price accuracy for a specific token
- Payment not included or insufficient (requires $0.01 USDC via x402 protocol)
