# Mint Intel: Base ERC-20 Token Balance

> Mint Intel: Base ERC-20 Token Balance is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Returns the ERC-20 token balance for any Base chain wallet address, including raw and decimal-adjusted amounts, token symbol, and decimals.

## 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 mint-intel-base-erc-20-token-balance-4300395b
```

Example prompt: What's the USDC balance of Base wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? Use the ERC-20 token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

## When to prefer this

Use this endpoint when you need the ERC-20 token balance of a specific Base chain wallet for a known token contract address. It is ideal for lightweight, single-address/single-token lookups with decimal normalization included. Prefer this over broader multi-token endpoints when you only need one specific token's balance on Base and want minimal cost per call.

## Known failure modes

- 404 returned if the token address is not a valid ERC-20 contract — no charge incurred
- Invalid or malformed wallet address returns an error
- Token contract exists but balanceOf reverts (non-standard ERC-20) may cause failure
- Network or RPC issues on Base may cause transient errors
- Address with zero balance returns 0 — not an error but may be misread as failure

## How this service works

ERC-20 token balance for any Base wallet - USDC, WETH, USDT or any token - via balanceOf (eth_call): raw and decimal-adjusted amount, symbol, decimals. Not a token -> 404, not charged.

## Output

Returns the wallet's ERC-20 token balance as both a raw integer string (balanceRaw) and a decimal-adjusted human-readable amount, along with the token's symbol and decimals. If the provided token address is not an ERC-20 contract, the API returns a 404 and does not charge.
