## When to prefer this

Choose this endpoint when you need a quick, single-call aggregated USD net worth for any EVM wallet across all major chains, leveraging DeBank's comprehensive multi-chain indexing — especially useful when you don't want to manage multiple chain-specific RPC calls or token price lookups yourself. Prefer this over raw RPC calls when cross-chain aggregation and USD valuation are needed in one response.

## Known failure modes

- Invalid or malformed EVM wallet address returns an error or empty result
- Unauthenticated request (missing X-PAYMENT header) returns a 402 Payment Required challenge
- Wallet with no on-chain history may return a zero balance
- DeBank upstream API downtime causes proxy to return an error
- Incorrect payment signature results in access denial

## How this service works

All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall.

Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.

## Output

Returns the aggregated total balance (in USD) of all tokens and assets held by the specified EVM wallet address across all supported blockchain networks, sourced from DeBank's multi-chain balance API.
