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

Computes real-time 5-minute delta shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket 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 prompt-guard-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-88f374df -d '<json body>'
```

Example prompt: What are the 5-minute alpha deltas for ETH right now — DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and any Polymarket odds movement?

## When to prefer this

Choose this endpoint when an autonomous trading bot or alpha-hunting agent needs real-time, stateful 5-minute delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call — especially for tokens active on Base, Arbitrum, or Solana. Prefer this over single-source feeds when cross-domain signal correlation (DEX + yield + prediction markets) is required for a trading decision.

## Known failure modes

- Missing or empty 'target' field returns a validation error
- Unknown or unsupported token symbol may return empty or null deltas
- Polymarket or DeFiLlama upstream outages can cause partial or stale data
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not resolved
- Timeout if upstream DEX or yield data sources are slow to respond

## 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://prompt-guard.agentdiet.dev/v1/alpha-stream)

## Output

Returns a structured object containing stateful 5-minute delta metrics for the requested token: DEX buy/sell ratio shift, DeFiLlama APY spread delta across relevant pools, and Polymarket odds movement, enabling autonomous agents to detect alpha signals and act on real-time market microstructure changes.
