## 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 heurist-mesh-usdc-daily-activity-aggregator-e9ab691a -d '<json body>'
```

Example prompt: Can you break down the daily USDC activity for wallet 0x1234abcd...5678 — I want to see how many transactions happened each day and how much was sent vs received, so I can spot any unusual volume spikes?

## When to prefer this

Use this endpoint when you need a time-series view of a wallet's USDC activity aggregated by day — ideal for forensic analysis, spotting behavioral patterns, or identifying anomalous spikes. Prefer this over raw transaction lookups when you need aggregated daily summaries rather than individual transaction details.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Wallet with no USDC activity returns zero counts or empty day buckets
- Network timeout if the Base chain data provider is slow
- Rate limiting or payment failure if the x402 payment of $0.005 USDC is not processed

## How this service works

Aggregate a wallet's USDC activity by calendar day, returning daily transaction counts and total volume received/sent. Use to spot active vs quiet periods and unusual volume spikes.

## Output

Returns a structured breakdown of USDC activity grouped by calendar day, including per-day transaction counts and total USDC volume received and sent, enabling identification of active periods, quiet days, and unusual volume spikes.
