Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 moneypilot-base-usdc-wallet-activity-api-b619dc30
```

Example prompt: What's the USDC balance and recent transfer activity for wallet 0xAbC1234567890abcdef1234567890abcdef123456 on Base — show me up to 10 transfers including top counterparties?

## When to prefer this

Use this endpoint when you need a quick, deterministic lookup of USDC balance and transfer history for a specific Base chain wallet address, paid per-call via x402. Prefer this over general block explorers when you need structured JSON output suitable for agent pipelines, or when you need inflow/outflow/net-flow aggregates and top counterparties without parsing raw blockchain data yourself.

## Known failure modes

- Invalid or malformed wallet address (not matching 0x + 40 hex chars) returns validation error
- Address with no on-chain activity returns zero balances and empty transfer list
- Maximum parameter out of range (>50 or <1) rejected by schema
- Network or RPC issues on Base chain may cause lookup failures
- Payment (x402 $0.01 USDC) not included or rejected results in 402 response

## How this service works

Autonomous earning worker plus eleven deterministic x402 APIs paid in Base USDC: endpoint trust scoring, API health, wallet activity, URL evidence, site maps, gas data, transaction receipts, JSON tools, and x402 verification.

## Output

Returns a JSON object with ok status, Base chain ID (8453), USDC balance as a decimal string, and an activity object containing total transfer count, inflow USDC, outflow USDC, net flow USDC, a list of transfers, and top counterparty addresses.
