## 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 agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-delta-stream-138f9a74
```

Example prompt: What are the 5-minute orderflow and yield delta signals for ETH right now — show me the DEX buy/sell ratio shift, DeFiLlama APY spread, and Polymarket odds movement.

## When to prefer this

Choose this endpoint when you need a single aggregated, stateful 5-minute delta view combining DEX orderflow, DeFi yield spreads, and prediction market odds for a specific token — particularly for autonomous trading bots or alert systems that need cross-domain momentum signals in one call rather than querying DexScreener, DeFiLlama, and Polymarket separately.

## Known failure modes

- Missing or invalid 'target' parameter returns an error
- Unknown token symbol returns empty or null deltas
- Upstream data source (DexScreener, DeFiLlama, Polymarket) unavailability causes stale or missing data
- Payment failure via x402 returns HTTP 402 before data is served
- Rate limiting if called too frequently beyond plan limits

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