## 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-f054809b
```

Example prompt: What are the current 5-minute momentum delta signals for ETH — including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements?

## When to prefer this

Choose this endpoint when you need a single fused, stateful momentum signal combining DEX orderflow, DeFi yield spreads, and Polymarket odds shifts for a specific token over a 5-minute window — especially for autonomous trading bots that need pre-computed alpha deltas rather than raw feed data. Prefer this over individual Polymarket or DeFiLlama endpoints when you want correlated, multi-source momentum in one call.

## Known failure modes

- Missing or invalid 'target' token symbol returns a validation error
- Unknown token symbols with no DEX/DeFiLlama coverage may return empty or null deltas
- Polymarket data may be unavailable for tokens without active prediction markets
- Rate limit or payment failure via x402 results in 402 Payment Required response
- Stale data if upstream DeFiLlama or Polymarket feeds experience latency
