## 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 seerium-dex-market-brief-api-a1015cbe
```

Example prompt: Give me a full DEX market brief for BTC-PERP — I want price, volume, funding heat, order book pressure across 10 levels, and the Seerium trading-agent signal all in one shot.

## When to prefer this

Use this endpoint when you need a consolidated, single-call DEX market brief for a crypto asset or perpetual pair — especially when you want price, volume, funding rate, order book pressure, and a trading-agent signal all in one response rather than calling multiple separate data APIs. Ideal for AI trading agents that need a fast, structured market snapshot per asset.

## Known failure modes

- Missing required 'symbol' parameter returns a 400 validation error
- Invalid or unrecognized symbol returns an error or empty result
- Order book levels outside 1-20 range rejected with validation error
- Payment not provided or invalid x402 payment header results in 402 Payment Required
- Upstream DEX data source unavailable causes partial or failed response
- Rate limiting if too many calls made without valid payment

## How this service works
