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

Computes and streams stateful 5-minute delta signals for a given token, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements.

## 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 defi-yield-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-d60877bd -d '<json body>'
```

Example prompt: Can you pull the latest 5-minute delta stream for AERO — I want to see the DEX buy/sell ratio shift, any DeFiLlama APY spread changes, and how Polymarket odds have moved?

## When to prefer this

Choose this endpoint when you need stateful, real-time 5-minute delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds for a single token — particularly for autonomous trading bots that require momentum and narrative shift detection rather than raw price feeds or static snapshots.

## Known failure modes

- Invalid or unrecognized token symbol returns an error or empty delta
- Token not listed on tracked DEX or DeFiLlama may return null fields
- Payment failure via x402 results in 402 status and no data
- Rate limiting or transient upstream data unavailability may cause partial or stale deltas
- Malformed request body (missing 'target' field) returns a 400-level validation 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://defi-yield.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a stateful delta object capturing the 5-minute change in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds for the specified token. The response reflects real-time shifts relative to the prior 5-minute window, enabling momentum and alpha signal detection for autonomous trading strategies.
