## 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 onchain-risk-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-e149b99d
```

Example prompt: What are the latest 5-minute orderflow and APY spread deltas for ETH right now — I need DEX buy/sell ratio shifts, DeFiLlama yield changes, and any Polymarket odds movement to feed my trading bot.

## When to prefer this

Choose this endpoint when you need stateful, 5-minute incremental delta signals across DEX orderflow, DeFi yield spreads, and Polymarket odds simultaneously for a single token — particularly for autonomous trading bots that need structured momentum signals rather than raw point-in-time snapshots. Prefer it over standalone DEX or DeFiLlama APIs when you want correlated multi-source alpha in a single call.

## Known failure modes

- Missing or invalid 'target' parameter returns a 400 error
- Unknown token symbol may return empty or null delta fields
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Upstream DexScreener, DeFiLlama, or Polymarket APIs unavailable causes degraded or partial response
- Rate limiting or quota exhaustion may return 429 Too Many Requests

## 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://onchain-risk.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a structured object containing stateful 5-minute computed deltas: DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements for the requested token, enabling autonomous trading bots to assess real-time momentum and narrative shifts.
