## 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 canaryguard-market-snapshot-dc30beb6
```

Example prompt: Pull a market snapshot for ETH, CBBTC, and USDC including Polymarket whale orderbook divergence — I need Base DEX spot and TWAP prices, Aerodrome and Uniswap V3 liquidity depth, and current perp funding rates.

## When to prefer this

Choose this endpoint when you need a unified, multi-dimensional market intelligence view combining on-chain DEX pricing, liquidity depth, perpetual funding rates, and prediction market signals in a single call — especially for Base ecosystem assets. Prefer it over single-purpose price feeds when you need to cross-reference spot/TWAP deviations against liquidity and sentiment in one snapshot.

## Known failure modes

- Unknown or unsupported asset ticker returns empty or error entry for that asset
- Polymarket data unavailable if include_polymarket is true but market does not exist for asset
- Stale data if on-chain RPC or Polymarket CLOB feed is lagging
- Payment failure or 402 not resolved results in no data returned
- Empty assets array returns an error or empty response
