## 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-c5c5e284
```

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, and any Polymarket odds changes right now.

## When to prefer this

Choose this endpoint when you need real-time, stateful 5-minute delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds for a specific token — particularly for autonomous trading bots that require actionable momentum data at sub-10-minute cadence. Prefer this over generic price feeds when you need multi-source alpha signals (DEX + DeFiLlama + Polymarket) in a single call.

## Known failure modes

- Missing or invalid 'target' parameter returns a 400-level error
- Unknown or unsupported token symbol may return empty or null signal data
- Transient data source unavailability (DeFiLlama, DEX feeds, Polymarket) may cause partial or degraded responses
- Payment failure via x402 may block the response entirely
- Rate limiting if called too frequently without valid payment

## 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/momentum-signals)
