## 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-solana-usdc-daily-activity-aggregator-a37d8136 -d '<json body>'
```

Example prompt: Show me the day-by-day USDC activity for Solana wallet 7xKX...abc — I want to see daily transaction counts and total volume sent and received so I can spot any unusual spikes.

## When to prefer this

Choose this endpoint when you need a time-series view of USDC activity on Solana broken down by calendar day — particularly for forensic analysis, anomaly detection, or behavioral profiling of a specific wallet. Prefer it over raw transaction listing endpoints when you want pre-aggregated daily summaries rather than individual transaction records.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error
- Wallet with no USDC transaction history returns empty data
- Network or RPC node unavailability causes timeout
- Date range with no activity returns zero-value rows
- Payment of 0.005 USDC not fulfilled causes 402 rejection

## 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 list of calendar days, each with the number of USDC transactions, total USDC volume received, and total USDC volume sent for a given Solana wallet address — enabling identification of active vs quiet periods and volume anomalies.
