## 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 preflight-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-18d1e1ca
```

Example prompt: Pull the latest 5-minute stateful delta for AERO — I want to see the DEX buy/sell ratio shift, DeFiLlama APY spread change, and any Polymarket odds movement right now.

## When to prefer this

Choose this endpoint when you need a stateful, incremental delta view of DeFi market signals — specifically the combination of DEX orderflow ratios, DeFiLlama yield spreads, and Polymarket odds — updated every 5 minutes for autonomous trading or monitoring bots. Prefer this over static price feeds or one-shot lookups when you need directional momentum signals rather than absolute values.

## Known failure modes

- Missing or invalid token symbol returns a validation error
- Token not tracked by DeFiLlama or Polymarket may return partial or empty delta data
- Payment not fulfilled (HTTP 402) if x402 micropayment header is absent or incorrect
- Stale state if the 5-minute window has not yet completed for a newly submitted token
- Service unavailable if upstream DEX, DeFiLlama, or Polymarket APIs are down

## 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://preflight.agentdiet.dev/v1/autonomous-trading-alpha)

## Output

A stateful delta snapshot covering: DEX buy/sell ratio change over the last 5-minute window, DeFiLlama APY spread shift, and Polymarket prediction market odds movement for the queried token or asset.
