## 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-3ca93dbe -d '<json body>'
```

Example prompt: Pull the latest 5-minute DEX buy/sell ratio delta, DeFiLlama APY spread shift, and Polymarket odds movement for AERO so my trading bot can act on fresh alpha signals.

## When to prefer this

Choose this endpoint when you need real-time, stateful 5-minute delta signals across DEX orderflow, DeFi yield spreads, and Polymarket odds simultaneously for a single token — especially for autonomous trading bots that need rolling alpha signals rather than point-in-time snapshots. Prefer this over generic price feeds when you need the rate-of-change (delta) rather than absolute values, or when you need cross-venue signal fusion (DEX + DeFiLlama + Polymarket) in a single call.

## Known failure modes

- Token symbol not recognized or unsupported — returns error or empty delta
- Upstream DeFiLlama or Polymarket data unavailable — stale or missing fields in response
- Rate limiting or payment failure via x402 — HTTP 402 response requiring USDC payment
- Malformed target string — validation error on required 'target' field
- Network timeout from upstream DEX or prediction market APIs — partial or null response

## 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/crypto-alpha)

## Output

Returns a structured object containing stateful 5-minute delta metrics for the requested token, including DEX buy/sell ratio shifts, DeFiLlama APY spread changes, and Polymarket odds movements, computed as rolling deltas for autonomous trading bot consumption.
