## 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 dt0ur-online-defi-liquidity-assessment-ee21c0c1 -d '<json body>'
```

Example prompt: Can you check the order-book bid depth and expected price slippage for swapping USDC on Base right now — I want to know if liquidity conditions are good before I execute a large trade.

## When to prefer this

Use this endpoint when an agent needs to evaluate DeFi swap conditions — specifically bid depth and slippage — across Base, Ethereum, or Solana before executing a token or stablecoin swap. Prefer it over generic price feeds when market impact and liquidity depth are the primary concern, not just spot price.

## Known failure modes

- Unsupported asset symbol returns an error or empty result
- Invalid or unsupported network name causes a validation error
- Network or on-chain data unavailability leads to stale or missing liquidity data
- Highly illiquid assets may return unreliable slippage estimates
- Rate limiting or payment failure returns a 402 or 429 error
