## 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 free-asset-radar-base-usdc-transfer-check-ced2c263
```

Example prompt: Can you check the USDC transfer activity on Base for this wallet — I want to know the total USDC transferred and how many transfers have been made?

## When to prefer this

Use this endpoint when you need a lightweight, fast check of USDC transfer totals and counts on the Base network, particularly within x402-enabled autonomous agent workflows where per-call micropayment billing is acceptable. Prefer this over full blockchain explorers when you only need aggregate transfer data rather than full transaction details.

## Known failure modes

- Invalid or missing query parameters returns an error response
- Address not found on Base network may return zero results or an error
- Network or edge worker downtime may cause 5xx responses
- Malformed request may return a parsing error
- Insufficient payment (x402) results in payment-required error before data is served

## How this service works

Stable edge-hosted x402 utilities for autonomous agents.

## Output

Returns a JSON object with a success boolean, the total USDC transferred as a string (e.g. '0.001'), and the number of transfers as an integer count.
