## 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 onchain-risk-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-8a6455d9
```

Example prompt: Pull the latest 5-minute alpha delta stream for ETH — I want to see how the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds have shifted in the last window.

## When to prefer this

Choose this endpoint when you need a stateful, multi-source 5-minute delta feed that combines DEX orderflow pressure, DeFi yield spreads, and prediction market odds into a single signal — especially for autonomous trading bots that need short-window alpha detection. Prefer this over single-source DEX or DeFiLlama APIs when cross-market convergence signals are required.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Token symbol not found in DexScreener or DeFiLlama returns empty or null deltas
- Upstream data source (DexScreener, DeFiLlama, Polymarket) unavailable causes partial or failed response
- Payment not processed (HTTP 402) blocks response delivery
- Generic object response schema means malformed responses may not surface obvious errors

## 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://onchain-risk.agentdiet.dev/v1/crypto-alpha)

## Output

Returns a structured object containing computed 5-minute delta values for the requested token, including shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds — designed for stateful autonomous trading bots to detect short-term alpha signals.
