## 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 email-verify-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-252c5861
```

Example prompt: Pull the latest 5-minute delta stream for ETH — I want to see the DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and any Polymarket odds movements right now.

## When to prefer this

Choose this endpoint when you need real-time, stateful 5-minute delta computations across DEX orderflow, DeFi yield spreads, and Polymarket odds simultaneously for a single token — especially for autonomous trading bots that need to act on short-interval alpha signals rather than raw or historical data snapshots.

## Known failure modes

- Missing or invalid 'target' parameter returns an error
- Unsupported or unrecognized token symbol may return empty or null delta data
- Rate limiting or payment failure (x402) if per-call fee is not settled
- Stale data if underlying DEX or DeFiLlama feeds are delayed
- Network timeout if real-time computation takes too long

## 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://email-verify.agentdiet.dev/v1/narrative-tracker)

## Output

A structured snapshot containing computed 5-minute deltas for the requested token: DEX buy/sell ratio changes, DeFiLlama yield/APY spread movements, and Polymarket prediction market odds shifts — designed for autonomous trading bots to act on stateful alpha signals.
