## 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 defi-yield-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-08f602de
```

Example prompt: What are the latest 5-minute DEX orderflow and DeFiLlama APY spread deltas for ETH, and have Polymarket odds shifted meaningfully in the last interval?

## When to prefer this

Choose this endpoint when you need a unified, stateful 5-minute delta view combining DEX orderflow, DeFi yield spreads, and prediction market odds for a single token — ideal for autonomous trading bots that require structured alpha signals without building separate integrations with DeFiLlama, DEX aggregators, and Polymarket individually.

## Known failure modes

- Missing or empty 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Stale upstream data from DeFiLlama or Polymarket may produce outdated deltas
- Payment failure (HTTP 402) if x402 micropayment is not properly attached
- Rate limiting if called too frequently beyond the 5-minute cadence

## 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://defi-yield.agentdiet.dev/v1/crypto-alpha)

## Output
