## 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 serp-extract-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-63b8ec94
```

Example prompt: Give me the latest 5-minute delta feed for ETH — show me the DEX buy/sell ratio shift, DeFiLlama APY spread change, and any Polymarket odds movement right now.

## When to prefer this

Choose this endpoint when you need stateful, time-windowed delta signals (not just a snapshot) across DEX orderflow, DeFi yield spreads, and prediction market odds simultaneously for a single token. It is ideal for autonomous trading bots that need to detect momentum shifts, yield arbitrage windows, or correlated on-chain and prediction-market moves within a 5-minute cadence rather than polling multiple separate APIs.

## Known failure modes

- Missing or invalid 'target' parameter returns a validation error
- Unrecognized token symbol may return empty or null deltas
- Upstream DexScreener, DeFiLlama, or Polymarket API outages may cause degraded or stale data
- Rate limiting or payment failure (HTTP 402) if x402 payment not completed
- Generic 500 error if stateful session data is unavailable for the requested 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://serp-extract.agentdiet.dev/v1/perps-funding-alpha)

## Output

Returns a structured object containing computed 5-minute delta values including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements for the requested token, enabling stateful comparison against the prior interval for alpha signal detection.
