## 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 prompt-guard-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-46a437f6
```

Example prompt: What are the latest 5-minute DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds deltas for ETH right now?

## When to prefer this

Choose this endpoint when you need stateful, incremental 5-minute delta signals across DEX orderflow, DeFi yield spreads, and prediction market odds for a specific token — particularly for autonomous trading bots that need to detect sector rotation or momentum shifts without reprocessing full historical datasets.

## Known failure modes

- Missing or invalid 'target' parameter returns an error
- Unknown or unsupported token symbol may return empty or null deltas
- Payment required (HTTP 402) if x402 USDC payment is not included
- Stale data if upstream DEX, DeFiLlama, or Polymarket feeds are delayed
- Rate limiting or access denial if quota is exceeded

## 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://prompt-guard.agentdiet.dev/v1/sector-rotation-feed)

## Output

Returns a structured delta snapshot containing: 5-minute change in DEX buy/sell ratio for the target asset, DeFiLlama APY spread shifts across relevant protocols, and Polymarket odds movement — enabling autonomous agents to detect momentum, sector rotation, or yield arbitrage signals in near-real-time.
