# 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 whale-momentum.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).

Computes and streams real-time 5-minute delta shifts in DEX buy/sell ratios, DeFiLlama APY spreads, and Polymarket prediction market 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 whale-momentum-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-7a2b3ba5 -d '<json body>'
```

Example prompt: Pull the latest 5-minute alpha delta stream for AERO — I want to see the DEX buy/sell ratio shift, any DeFiLlama APY spread changes, and how Polymarket odds have moved in the last window.

## When to prefer this

Choose this endpoint when you need stateful, windowed delta signals — not just raw snapshots — across DEX orderflow, DeFi yield spreads, and prediction market odds simultaneously for a specific token. It is purpose-built for autonomous trading bots that need momentum context across multiple on-chain and off-chain data sources in a single call, rather than stitching together separate DEX, DeFiLlama, and Polymarket API calls manually.

## Known failure modes

- Missing or empty 'target' field returns a validation error
- Unknown or illiquid token symbol may return empty or null deltas
- Upstream DeFiLlama or Polymarket data unavailability may cause partial results
- Network timeout if upstream oracles are slow
- Idempotency-Key collision may replay a cached response rather than fresh data

## 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://whale-momentum.agentdiet.dev/v1/crypto-alpha)

## Output

Returns a structured object containing stateful 5-minute delta metrics for the requested token, including DEX buy/sell ratio changes, DeFiLlama APY spread shifts, and Polymarket odds movement — computed relative to the prior 5-minute window to surface actionable alpha signals for trading bots.
