## 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 alpha-stream-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-3bde9134
```

Example prompt: Pull the latest 5-minute momentum delta signals for ETH — I want to see the DEX buy/sell ratio shift, DeFiLlama APY spread change, and Polymarket odds movement right now.

## When to prefer this

Choose this endpoint when you need stateful, real-time 5-minute delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call — especially for autonomous trading bots that need aggregated alpha signals rather than raw data from individual sources like DeFiLlama or Polymarket directly.

## Known failure modes

- Missing or empty 'target' parameter returns a 400 validation error
- Unknown or unsupported token symbol may return empty or null signal fields
- Payment not fulfilled (HTTP 402) if x402 USDC micropayment is not included
- Stale data if upstream DeFiLlama or Polymarket feeds are delayed
- Rate limiting or service unavailability returns 5xx errors

## How this service works
