# 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 mcp-security.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 ratios, DeFiLlama APY spreads, and Polymarket odds for a given token or asset symbol.

## 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 mcp-security-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-34710823 -d '<json body>'
```

Example prompt: Pull the latest 5-minute delta stream for ETH — I want to see real-time shifts in the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds so my trading bot can act on fresh alpha.

## When to prefer this

Choose this endpoint when an autonomous trading agent needs a single, unified, stateful 5-minute alpha signal combining DEX orderflow sentiment, DeFi yield spreads, and prediction market odds for a specific token — especially when running on a tight polling loop and requiring low-latency, low-cost ($0.01/call) per-tick intelligence rather than querying multiple data sources separately.

## Known failure modes

- Empty or invalid token symbol returns a validation error
- Token symbol not tracked by DeFiLlama or Polymarket may return partial or null deltas
- Rate limiting or payment failure via x402 returns HTTP 402 with payment details
- Stale or unavailable upstream DEX data may cause incomplete delta computation
- Idempotency-Key collision may return a cached prior response rather than fresh computation

## 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://mcp-security.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a stateful delta object capturing the latest 5-minute shifts across three signal layers: DEX buy/sell ratio change, DeFiLlama APY spread movement, and Polymarket implied probability shift — all scoped to the requested token or asset symbol.
