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

Computes real-time 5-minute momentum signals for a given token, including DEX buy/sell ratio shifts, DeFiLlama APY spread deltas, and Polymarket odds changes for autonomous trading bots.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 domain-osint-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-b72c2abc -d '<json body>'
```

Example prompt: Pull the latest 5-minute momentum signals for ETH — I want to see the DEX buy/sell ratio shifts, DeFiLlama APY spread deltas, and any Polymarket odds changes right now.

## When to prefer this

Choose this endpoint when an autonomous trading agent needs stateful, incremental momentum signals rather than raw orderbook snapshots — specifically when you need DEX buy/sell ratio deltas, DeFiLlama APY spreads, and Polymarket odds shifts computed over a rolling 5-minute window for a single token. Prefer this over generic price feeds when you need cross-venue alpha signals (DEX + yield + prediction market) combined in one call.

## Known failure modes

- Missing or empty 'target' field returns a 400 validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Payment failure (HTTP 402) if x402 USDC micropayment is not correctly submitted
- Network or upstream data provider outage may return a 503 or partial result
- Rate limiting may occur under high-frequency polling without proper idempotency key handling

## 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://domain-osint.agentdiet.dev/v1/momentum-signals)

## Output

Returns a JSON object containing stateful 5-minute deltas for the requested token, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements — representing the most recent momentum snapshot computed against the prior 5-minute window.
