# 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 real-time 5-minute rolling deltas in DEX buy/sell ratios, 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-fc19a3ca -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need stateful, real-time 5-minute rolling delta signals across multiple DeFi dimensions (DEX orderflow, yield spreads, prediction market odds) for a single token — especially for autonomous trading bots that need a unified alpha feed rather than querying DEX, DeFiLlama, and Polymarket separately. Prefer this over single-source DEX scanners when cross-signal correlation (e.g. APY spread diverging while buy pressure rises) is important for decision-making.

## Known failure modes

- Missing or empty 'target' field returns validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Network latency or upstream DEX/DeFiLlama/Polymarket data unavailability may cause stale or incomplete deltas
- Payment failure via x402 results in 402 response blocking data delivery
- Rapid consecutive calls without Idempotency-Key may produce duplicate billing

## 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/alpha-stream)

## Output

Returns a structured object containing real-time 5-minute rolling delta values for the requested token, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes between protocols, and Polymarket prediction market odds movements — designed as stateful alpha signals for autonomous trading agents.
