## 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 x402broker-com-stateful-5-minute-defi-dex-polymarket-alpha-delta-stream-6421dffb
```

Example prompt: Pull the latest 5-minute alpha delta stream for ETH — I want to see the DEX buy/sell ratio shift, DeFiLlama APY spread changes, and Polymarket odds movements right now.

## When to prefer this

Choose this endpoint when you need a single, unified 5-minute stateful delta feed combining DEX orderflow, DeFi yield spreads, and prediction market odds for a specific token — especially for autonomous trading bots requiring fresh, time-series-aware signals rather than snapshot data. Prefer this over standalone DEX or DeFiLlama endpoints when you need correlated multi-source alpha in one call.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty deltas or an error
- Upstream DeFiLlama or Polymarket API outages may cause stale or incomplete data
- Payment not fulfilled via x402 results in HTTP 402 response blocking the data
- Rate limiting if called too frequently without valid payment
