## 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 xx402-base-wallet-batch-risk-api-a70a7c64
```

Example prompt: Can you pull a batch risk profile for wallet 0xba76c7ECa175f67cFcE475c09498f840176bf497 on Base, checking the last 1000 blocks of USDC activity, with up to 4 counterparty rows, so I know whether it's safe to interact with?

## When to prefer this

Choose this endpoint when you need comprehensive on-chain risk intelligence for Base/EVM wallets — especially when screening counterparties before DeFi interactions, onboarding new buyers/sellers in an x402 payment context, or when an autonomous agent needs a structured trust verdict with actionable queues (watchlist, review, avoid). Prefer this over generic blockchain explorers when you need pre-packaged risk scores, entity resolution, and agent-ready decision output in a single call.

## Known failure modes

- Payment not received (402 response) if x402 payment header is missing or insufficient
- Invalid address format returns schema validation error
- Exceeding limit=5 or detail_limit=8 caps silently truncates results
- Token address not on Base returns empty or null token data
- Block window outside 100-2000 range rejected with parameter error
- Rate limiting or upstream chain-read failures may return partial data

## How this service works

Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.

## Output

Returns a structured JSON payload including: a batch decision summary, per-wallet risk breakdowns, wallet enrichment profiles, entity resolution, trust checklists, priority/watchlist/review/avoid queues, approval spender exposure, counterparty lists, buyer execution plan, agent intake plan, source status, and a disclaimer. Effectively a complete risk dossier for each queried address.
