# 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 whale-momentum.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Computes and streams 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 whale-momentum-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-e8318235
```

Example prompt: Give me the latest 5-minute delta feed for ETH — I want to see the DEX buy/sell ratio shift, any DeFiLlama APY spread changes, and whether Polymarket odds have moved.

## When to prefer this

Choose this endpoint when you need stateful, rolling 5-minute delta signals across DEX orderflow, DeFi yield spreads, and Polymarket odds simultaneously for a specific token — especially for autonomous trading bots that need integrated cross-signal alpha detection rather than querying each data source separately.

## Known failure modes

- Missing or invalid 'target' parameter returns an error
- Unknown or unsupported token symbol may return empty or null deltas
- Stale data if upstream DEX or DeFiLlama feeds are delayed
- HTTP 402 payment required if x402 payment header is missing or insufficient
- Rate limiting if called too frequently without valid payment

## 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://whale-momentum.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a structured delta object containing the computed 5-minute shifts for the requested token: DEX buy/sell ratio change, DeFiLlama APY spread movement, and Polymarket odds delta, enabling autonomous agents to detect momentum, yield, and sentiment shifts in near-real-time.
