## 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-onchain-risk-radar-1d1517a2
```

Example prompt: Run an onchain risk radar scan on Base for aerodrome, virtual, and base tokens — show me up to 6 token discovery candidates, 8 DEX pair anomalies, and 10 DeFi risk rows, only including pairs with at least $50,000 liquidity and $500 daily volume.

## When to prefer this

Choose this endpoint when you need a comprehensive onchain risk assessment specifically for the Base blockchain, including token discovery, DEX pair anomaly detection, and DeFi yield risk flags in a single call. Prefer it over generic token screeners when you need contract-control probes, x402 buyer/seller discovery signals, and agent-ready risk queues (priority/review/avoid) in one structured response.

## Known failure modes

- Invalid query parameter format returns 400 error
- deep_limit exceeding 2 or defi_limit outside 3–10 causes validation failure
- Payment not received results in 402 response requiring x402 USDC micropayment
- Upstream Base chain RPC or DeFi data source unavailable returns partial or degraded data
- min_liquidity_usd or min_volume_24h_usd set too high may return empty discovery results

## 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 JSON object with: a summary risk verdict, onchain risk decision and verdict, chain-read risk checklist, token discovery candidates (with contract control probes), DEX pair anomalies, DeFi risk rows with yield flags, priority/review/avoid queues, bucket counts, source status, agent operation plan, and next recommended paid calls — plus a not-financial-advice disclaimer.
