## 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 hn-pulse-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-26653115
```

Example prompt: Pull the latest 5-minute DEX orderflow and Polymarket odds delta for ETH — I want to see if the buy/sell ratio and yield spreads are shifting before I make a trade.

## When to prefer this

Choose this endpoint when you need a consolidated, stateful 5-minute delta signal combining DEX orderflow, DeFi yield spreads, and prediction market odds for a single token — especially for autonomous trading bots making rotation decisions. Prefer it over raw DEX or DeFiLlama APIs when you need pre-computed deltas across multiple data sources in a single call.

## Known failure modes

- Missing or invalid 'target' parameter returns a 400-level error
- Unknown or illiquid token symbol may return empty or null deltas
- Payment not completed via x402 returns HTTP 402 Payment Required
- Upstream DEX or DeFiLlama data unavailable causes partial or stale response
- Polymarket market not found for the given token results in null odds delta

## How this service works

Stateful 5-minute delta feed for autonomous trading bots: computes real-time shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds. (Live x402 v2, IETF MPP & MCP endpoint at https://hn-pulse.agentdiet.dev/v1/sector-rotation-feed)

## Output

Returns a structured object containing 5-minute delta values for the specified token: DEX buy/sell ratio shift, DeFiLlama APY spread change, and Polymarket odds movement, computed stateably from the prior interval to support autonomous trading decisions.
