# 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 x402-audit.agentdiet.dev, paid per call via MPP, $0.03/call, status unknown (last checked 2026-10-21).

Computes and streams real-time 5-minute delta shifts in DEX buy/sell ratios, DeFiLlama APY spreads, and Polymarket prediction market 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 x402-audit-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-77d50853
```

Example prompt: Can you pull the latest 5-minute orderflow and APY delta stream for ETH — I want to see whether buy/sell pressure and DeFiLlama yield spreads are shifting right now, along with any Polymarket odds movement?

## When to prefer this

Choose this endpoint when you need stateful, time-windowed delta signals (not just snapshots) across DEX orderflow, DeFi yields, and prediction markets simultaneously for autonomous trading or alpha detection. Prefer this over raw DEX or DeFiLlama APIs when you want pre-computed 5-minute shift metrics rather than raw pool data, and when Polymarket sentiment correlation is relevant to your strategy.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Upstream DexScreener/DeFiLlama/Polymarket data unavailable causes partial or null deltas
- Stale state if called more frequently than the 5-minute update window
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed
- Rate limiting if called excessively in a short window

## 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://x402-audit.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a structured snapshot of stateful 5-minute deltas including: DEX buy/sell ratio shifts (orderflow pressure), DeFiLlama APY spread changes across protocols, and Polymarket prediction market odds movement — all keyed to the specified token symbol and computed against the prior 5-minute state window.
