## 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 domain-osint-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-b477c9f4
```

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

## When to prefer this

Choose this endpoint when you need short-term (5-minute window) stateful delta signals across DEX orderflow, DeFi yield spreads, and prediction market odds simultaneously for a specific token — particularly for autonomous trading bots that need momentum detection or alpha signals without maintaining their own stateful aggregation layer.

## Known failure modes

- Missing or invalid 'target' token symbol returns a 400 validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Payment not completed (HTTP 402) blocks response when x402 payment is not attached
- Stale data if upstream DexScreener, DeFiLlama, or Polymarket APIs are delayed or rate-limited
- Generic 500 error if aggregation pipeline fails for a given asset

## 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://domain-osint.agentdiet.dev/v1/narrative-tracker)

## Output

Returns a structured object containing stateful 5-minute delta metrics for the queried token, including DEX buy/sell ratio changes, DeFiLlama APY spread shifts, and Polymarket odds movements — enabling detection of short-term momentum and narrative changes.
