# Stateful 5-Minute DeFi, DEX & Polymarket Alpha Delta Stream

> Stateful 5-Minute DeFi, DEX & Polymarket Alpha Delta Stream is a paid API for AI agents from serp-extract.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Computes real-time 5-minute delta shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket prediction odds for a given token or asset.

## 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 serp-extract-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-266fe5ea
```

Example prompt: What are the current 5-minute DEX buy/sell ratio shifts, DeFiLlama APY spreads, and Polymarket odds deltas for ETH right now?

## When to prefer this

Choose this endpoint when you need a unified, stateful 5-minute momentum signal combining DEX orderflow, yield spreads, and prediction market odds in a single call — particularly for autonomous trading bots that require low-latency alpha signals without stitching together multiple upstream APIs. Prefer this over raw DexScreener or DeFiLlama calls when you want pre-computed deltas rather than raw snapshots.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Stale or unavailable upstream data (DexScreener, DeFiLlama, Polymarket downtime) may return incomplete deltas
- Missing required 'target' parameter results in validation error
- Rate limiting or payment failure (x402) blocks the request
- Highly illiquid tokens may return null delta values due to insufficient orderflow

## 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://serp-extract.agentdiet.dev/v1/momentum-signals)

## Output

Returns a structured object containing stateful 5-minute delta values for the requested token, including DEX buy/sell ratio momentum, DeFiLlama APY spread changes, and Polymarket odds movements — designed to surface alpha signals for autonomous trading systems.
