## 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-liquidity-exit-risk-feed-2e0be239
```

Example prompt: Check exit-risk signals on Base chain for BRETT (0x532f27101965dd16442E59d40670FaF5eBB142E4) and DEGEN (0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed) — look at the last 200 blocks, return the top 10 risk alerts, include up to 8 pair anomaly rows, and flag any large transfers above $50,000.

## When to prefer this

Choose this endpoint when you need real-time, ranked DeFi exit-risk intelligence specifically for Base chain ERC-20 tokens, including contract-control probes, whale transfer detection, and DEX pair anomaly signals — particularly useful before entering a position or for continuous autonomous risk monitoring of a Base token portfolio. Prefer alternatives for Ethereum mainnet, Solana, or other chains, or for price-only queries without risk context.

## Known failure modes

- Invalid or non-Base token address returns empty targeted checks or error
- Token address with no on-chain history returns minimal signal rows
- DEX search terms returning no Dexscreener matches yields sparse pair anomaly data
- Rate limiting or payment failure (402) if x402 payment header is missing or insufficient
- window_blocks below minimum (100) rejected by schema validation
- min_liquidity_usd set too high may filter all pairs, returning empty pair anomaly radar

## 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
