## 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 x402broker-com-stateful-5-minute-defi-dex-polymarket-alpha-delta-stream-2dbee11b
```

Example prompt: Pull the latest 5-minute delta stream for ETH — I want to see if the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds have shifted significantly in the last interval.

## When to prefer this

Choose this endpoint when you need stateful, 5-minute rolling delta signals combining DEX orderflow, DeFi yield spreads, and prediction market odds in a single call for a specific token — especially for autonomous trading bots that need composite alpha signals rather than raw price feeds or single-source data alone.

## Known failure modes

- Missing or invalid 'target' parameter returns an error
- Unknown or unsupported token symbol may return empty or null delta fields
- Rate limiting or payment failure (x402) blocks access
- Upstream data source (DeFiLlama, Polymarket, DEX feed) outage causes stale or missing deltas
- Very low-liquidity tokens may have insufficient orderflow 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://x402broker.com/v1/narrative-tracker)

## Output

Returns a structured object containing real-time 5-minute delta values for the requested token, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements, enabling autonomous trading bots to detect short-term alpha signals and yield arbitrage opportunities.
