## 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-2099b363
```

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

## When to prefer this

Choose this endpoint when you need stateful, short-window (5-minute) delta signals that combine DEX orderflow, DeFi yield spreads, and prediction market odds in a single call for a specific token — especially for autonomous trading bots that need real-time momentum and arbitrage signals rather than raw price feeds or simple liquidity snapshots.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Downstream data source outage (DexScreener, DeFiLlama, Polymarket) may cause stale or incomplete signals
- Payment failure via x402 returns HTTP 402 with payment required details
- Rate limiting may apply if called too frequently without sufficient payment
