## 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-09f128f3 -d '<json body>'
```

Example prompt: Give me the latest 5-minute delta stream for ETH — I want to see how the DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket odds have shifted so I can spot any emerging alpha.

## When to prefer this

Choose this endpoint when an autonomous trading bot or DeFi agent needs a unified, stateful 5-minute delta view combining DEX orderflow, yield spreads, and prediction market odds for a single token — rather than calling DeFiLlama, a DEX API, and Polymarket separately and computing deltas manually.

## Known failure modes

- Missing or empty 'target' field returns a 400 validation error
- Unknown or unsupported token symbol may return empty or null deltas
- Payment not included or insufficient (HTTP 402) blocks execution
- Upstream DeFiLlama or Polymarket data unavailability may cause partial or stale results
- Rate limiting or network timeout may return 429 or 503

## 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/narrative-tracker)

## Output

Returns a stateful delta object capturing 5-minute shifts in DEX buy/sell ratio, DeFiLlama APY spreads, and Polymarket implied odds for the requested token, enabling autonomous bots to detect momentum and yield changes in near real-time.
