## 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 alpha-stream-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-457a7597
```

Example prompt: Pull the latest 5-minute alpha delta stream for ETH — I want to see how the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds have shifted in the last interval.

## When to prefer this

Choose this endpoint when you need sub-minute stateful delta intelligence across DEX orderflow, DeFi yield spreads, and prediction market odds simultaneously for a single asset — especially for autonomous trading bots that need incremental change signals rather than full snapshots. Prefer over generic price feeds when you need cross-signal alpha (DEX + DeFi + Polymarket) in a single call with built-in statefulness across 5-minute windows.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty deltas or an error
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed
- Upstream data source (DeFiLlama, DEX, Polymarket) outage may cause stale or missing deltas
- Rate limiting if called too frequently beyond micropayment flow

## 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://alpha-stream.agentdiet.dev/paid)

## Output

A JSON object containing stateful 5-minute delta values for the requested asset, including: DEX buy/sell ratio shift, DeFiLlama APY spread change, and Polymarket odds movement relative to the prior 5-minute window — designed to feed autonomous trading bot decision loops.
