## 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 mcp-security-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-db98f20b
```

Example prompt: Can you pull the latest 5-minute momentum delta for ETH — I want to see how the DEX buy/sell ratio, DeFiLlama APY spread, and Polymarket odds have shifted?

## When to prefer this

Choose this endpoint when you need a stateful, time-windowed (5-minute) composite signal combining DEX orderflow, DeFi yield spreads, and prediction market odds for a single token — especially for autonomous trading bots that need momentum signals rather than raw price data. Prefer this over raw DEX liquidity APIs when you want pre-computed deltas rather than point-in-time 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
- DexScreener, DeFiLlama, or Polymarket upstream outages may result in partial or stale data
- Rate limiting or payment failure (x402) may block access
- Very low-liquidity tokens may have insufficient data for meaningful deltas

## 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://mcp-security.agentdiet.dev/v1/momentum-signals)

## Output

Returns a structured object containing real-time 5-minute delta metrics for the requested token: DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements, enabling momentum-based trading decisions.
