## 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 no-hands-ai-base-stablecoin-balance-checker-1045f184
```

Example prompt: What are the current USDC, USDT, and DAI balances for Base address 0xAbCd...1234, and what are their live USD reference rates?

## When to prefer this

Choose this endpoint when you need a single call that returns all three major stablecoins (USDC, USDT, DAI) on the Base network simultaneously, especially when you also need USD reference rates for budget calculations or agent treasury checks. Prefer this over general blockchain explorers when you specifically need Base-native stablecoin data with USD context in a single lightweight call.

## Known failure modes

- Invalid or malformed Base wallet address returns an error
- Address with no stablecoin holdings returns zero balances
- Network congestion or RPC issues may delay balance retrieval
- USD reference rate feed unavailable causes partial response
- Rate limit exceeded returns 429 or payment required error

## How this service works

Return live Base USDC, USDT, and DAI balances with public USD reference rates.

## Output

Returns live on-chain balances for USDC, USDT, and DAI tokens on the Base network for the specified address, along with public USD reference rates for each stablecoin, enabling budget and portfolio assessments.
