# 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 defi-yield.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 odds for a specified 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 defi-yield-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-fc6eb5a5
```

Example prompt: Give me the latest 5-minute alpha delta signals for ETH — including the DEX buy/sell ratio shift, DeFiLlama APY spread changes, and any Polymarket odds movement.

## When to prefer this

Choose this endpoint when you need a unified, stateful 5-minute delta view combining DEX orderflow pressure, DeFi yield spread changes, and prediction market odds shifts for a single token — especially for autonomous trading bots that need a compact, pre-computed alpha signal rather than raw data from three separate APIs.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Token symbol not found in DEX or DeFiLlama data returns empty or null deltas
- Polymarket data unavailable for specified asset returns partial response
- Rate limiting or payment failure (HTTP 402) if micropayment not processed
- Upstream API (DexScreener, DeFiLlama, Polymarket) outage causes degraded or stale 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://defi-yield.agentdiet.dev/v1/defi-signals)

## Output

Returns a structured object containing computed 5-minute deltas for the specified token, including shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket implied odds — enabling autonomous trading bots to detect actionable alpha signals in real time.
