## 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 mesh-heurist-xyz-f1313498 -d '<json body>'
```

Example prompt: Pull up the USDC activity profile for wallet 0x1234...abcd on Base — I want to know when it first and last moved USDC, how many transfers it made, and the total in vs out with net flow.

## When to prefer this

Use this endpoint when you need a quick, high-level USDC forensic summary for a specific wallet on the Base chain — including lifetime transfer counts, in/out totals, and activity window — without needing full transaction-level detail. Prefer this over general blockchain explorers when you want a structured, agent-ready analytics response specifically scoped to USDC on Base.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet has no USDC activity on Base — returns zero values or empty profile
- Base chain RPC or indexer unavailable — upstream timeout or error
- Payment of $0.005 USDC not fulfilled — 402 payment required error
- Rate limiting or quota exceeded on the Heurist mesh endpoint

## How this service works

Get a wallet's USDC activity summary on Base: first/last seen timestamps, total transfer count, aggregate USDC in/out and net flow. Use this for a quick financial snapshot before drilling into details.

## Output

Returns a structured summary including: first-seen and last-seen timestamps, total number of USDC transfers, cumulative USDC received (in), cumulative USDC sent (out), and the net USDC flow (in minus out) for the specified wallet on Base.
