# 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 x402broker.com, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Computes real-time 5-minute delta shifts 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 x402broker-com-stateful-5-minute-defi-dex-polymarket-alpha-delta-stream-9bc3bb64
```

Example prompt: Track the 5-minute orderflow and yield delta signals for ETH right now — 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 building autonomous trading bots or DeFi monitoring agents that need stateful, cross-signal alpha — specifically the convergence of DEX orderflow momentum, yield spread shifts, and prediction market odds changes in a single 5-minute delta snapshot. Prefer this over single-source feeds (e.g. the standalone Polymarket odds endpoint or the DeFi yield scanner alone) when you need correlated multi-signal delta analysis for a specific token in one call.

## Known failure modes

- Missing or invalid 'target' token symbol returns a validation error
- Token symbol not tracked by DeFiLlama or Polymarket may return empty or partial deltas
- Upstream DEX or Polymarket data unavailability may result in stale or incomplete delta values
- Rate limiting or payment failure (x402) may block the response
- Very new or low-liquidity tokens may have insufficient orderflow for meaningful delta computation

## 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://x402broker.com/v1/perps-funding-alpha)

## Output

Returns a structured object containing real-time 5-minute delta computations: DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket implied probability movements for the requested token or asset, enabling stateful comparison against the prior interval.
