# EVM Multi-Chain Balance Checker (BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain)

> EVM Multi-Chain Balance Checker (BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain) is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-03).

Returns native coin balance, USDC, USDT, and nonce for an EVM address across seven chains: BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, and Unichain.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability evm-multi-chain-balance-checker-bnb-avalanche-gnosis-linea-scroll-d2b63bef -d '<json body>'
```

Example prompt: What are the native coin, USDC, and USDT balances for wallet 0xF977814e90dA44bFA03b6295A0616a897441aceC on BNB Chain, Avalanche, and Linea — and how many transactions has it sent on each?

## When to prefer this

Choose this endpoint when you need multi-chain balance data specifically for BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, or Unichain — chains not covered by the sibling endpoint that handles Ethereum mainnet and other common chains. It's ideal for DeFi portfolio aggregation, airdrop eligibility checks, or whale tracking across newer EVM ecosystems. The nonce output makes it useful for wallet activity analysis without needing a separate transaction count query.

## Known failure modes

- Invalid or malformed EVM address returns an error or empty result
- Unsupported network name in the networks array is ignored or causes an error
- Public node downtime may result in null values for one or more chains
- Missing required 'address' field causes a schema validation error
- Rate limiting or payment failure (x402) may block the request

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the queried address, data source attribution, and an array of per-network objects each with: network name, native coin symbol, native balance (as a decimal number), USDC balance, USDT balance, and nonce (number of transactions sent from the address).
