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

Computes and returns 5-minute rolling deltas in DEX buy/sell ratio, 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 serp-extract-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-5a20ca84 -d '<json body>'
```

Example prompt: Pull the latest 5-minute alpha delta stream for ETH — I want to see how the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds have shifted in the last interval.

## When to prefer this

Choose this endpoint when you need a stateful, short-interval (5-minute) delta feed combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call. It is especially suited for autonomous trading bots that need composite alpha signals rather than a single data source. Prefer this over standalone Polymarket or DeFiLlama APIs when you need cross-market shift correlation for a specific token.

## Known failure modes

- Invalid or unrecognized token symbol returns an error or empty delta
- Missing required 'target' field causes a 400-level validation error
- Payment not processed (HTTP 402) if x402 micropayment header is absent or rejected
- Stale or unavailable upstream data (DeFiLlama, DEX, Polymarket) may result in degraded or partial deltas
- Network timeout or service unavailability returns 5xx error

## 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://serp-extract.agentdiet.dev/v1/perps-funding-alpha)

## Output

Returns a structured object containing the 5-minute delta values for the requested token, including DEX buy/sell ratio changes, DeFiLlama APY spread shifts, and Polymarket implied probability movements. The response reflects stateful comparison against the prior 5-minute window, enabling trend detection for autonomous trading agents.
