## 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 x402-audit-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-41333a3a
```

Example prompt: Pull the latest 5-minute DEX buy/sell ratio delta, DeFiLlama APY spread shift, and Polymarket odds movement for ETH right now — I need the stateful alpha stream to decide whether to enter a position.

## When to prefer this

Choose this endpoint when an autonomous trading bot or agent needs short-interval (5-minute) stateful delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call — especially for tokens traded on DEXes with active Polymarket markets. Prefer this over generic price feeds when you need multi-source alpha confirmation rather than raw price alone.

## Known failure modes

- Missing or invalid 'target' token symbol returns a 400 validation error
- Unknown or unsupported token symbol may return empty deltas or a 404
- Payment failure via x402 protocol returns a 402 Payment Required response
- Upstream data source (DeFiLlama, DEX feed, Polymarket) outage may cause stale or missing delta values
- Rate limiting or quota exhaustion may result in 429 Too Many Requests

## 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://x402-audit.agentdiet.dev/v1/crypto-alpha)

## Output

A JSON object containing the computed 5-minute delta values for the specified asset, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements — representing real-time alpha signals statefully tracked over the prior 5-minute window.
