## 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 whale-momentum-agentdiet-dev-stateful-5-minute-defi-dex-polymarket-ad932321
```

Example prompt: Pull the latest 5-minute momentum delta signals for SOL — I want to see the DEX buy/sell ratio shift, any APY spread changes from DeFiLlama, and how Polymarket odds have moved.

## When to prefer this

Choose this endpoint when you need stateful, incremental 5-minute momentum signals combining DEX orderflow, DeFi yield spreads, and Polymarket prediction market data in a single call — particularly for autonomous trading bots that need low-latency, pre-computed delta signals rather than raw on-chain data they must process themselves.

## Known failure modes

- Missing or empty 'target' parameter returns a validation error
- Unknown or unsupported token symbol may return empty or null delta fields
- Data freshness lag if upstream DEX, DeFiLlama, or Polymarket feeds are delayed
- HTTP 402 Payment Required if x402 micropayment is not included or fails
- Rate limiting if too many calls are made in a short window

## 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://whale-momentum.agentdiet.dev/v1/momentum-signals)

## Output

Returns a structured object containing stateful 5-minute delta metrics for the requested token, including DEX buy/sell ratio changes, DeFiLlama APY spread movements, and Polymarket odds shifts — enabling autonomous trading bots to detect momentum inflection points.
