## 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-stable-asset-risk-feed-2e8aa671
```

Example prompt: Can you pull the stable asset risk feed for USDC, DAI, and USDT on Base — show up to 15 assets and include up to 4 DEX pair lookups, keeping pools with any liquidity?

## When to prefer this

Choose this endpoint when you need structured, risk-tiered intelligence specifically about stablecoins on the Base blockchain, including DEX pair liquidity and volume signals, rather than general token prices or cross-chain data. It is best suited for autonomous agents performing treasury management, DeFi risk assessment, or stablecoin portfolio monitoring on Base.

## Known failure modes

- Invalid or unrecognized asset symbol returns empty or partial results
- dex_limit exceeding 6 or limit exceeding 20 causes a validation error
- Dexscreener or on-chain data sources temporarily unavailable leading to degraded source_status
- Payment not accepted or x402 protocol failure returns 402 with buyer_next_action guidance
- min_liquidity_usd or min_volume_24h_usd set too high filters out all 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
