## 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 hn-pulse-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-alpha-948f85ee
```

Example prompt: Can you pull the latest 5-minute delta signals for ETH — I want to see shifts in the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds right now so my trading bot can decide whether to act.

## When to prefer this

Choose this endpoint when an autonomous trading bot or agent needs real-time, stateful 5-minute delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call. Prefer it over static price feeds or single-source analytics when cross-market alpha detection and momentum-based decision-making are required.

## Known failure modes

- Missing or empty 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Payment not completed (HTTP 402) if x402 micropayment is not fulfilled
- Stale data if upstream DEX, DeFiLlama, or Polymarket feeds are delayed
- Rate limiting if called too frequently within a short window
