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 base-onchain-risk-token-intelligence-api-8b8f6ba5
```

Example prompt: Pull the latest Base onchain risk feed — search for aerodrome, virtual, and base tokens — and show me up to 10 ranked risk actions, 4 DeFi rows, 4 yield-pool rows, 3 DEX pair anomalies, and flag any large transfers above $100,000.

## When to prefer this

Choose this endpoint when you need a comprehensive, ranked, actionable risk feed specifically for the Base blockchain covering multiple risk dimensions (DeFi, tokens, DEX pairs, stable assets, contract controls, yield pools, large transfers) in a single call. Prefer it over general blockchain analytics when you need Base-specific risk signals with live contract-control probes and you're comfortable paying $0.01 USDC per call via x402.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Invalid query parameter types or out-of-range values (e.g. limit > 20) — returns 400 Bad Request
- Upstream onchain data sources unavailable — partial results with degraded source_status
- Rate limiting if too many calls in a short window — returns 429 Too Many Requests
- Network timeout if deep_limit probes take too long on live contract calls
