## 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 predge-polymarket-whale-trades-feed-0ac16195
```

Example prompt: Pull the latest 20 whale trades from Polymarket — the ones over $10k — and show me which market they're trading, whether they're buying YES or NO, and each wallet's Predge score.

## When to prefer this

Use this endpoint when you need a broad, recent snapshot of all large Polymarket trades across all markets, including wallet quality signals (Predge score). Prefer this over the per-market or per-wallet endpoints when you want a cross-market view of whale activity rather than drilling into a specific market or trader profile.

## Known failure modes

- limit parameter out of range (must be 1–100) returns a 400 error
- payment not attached or insufficient USDC causes a 402 error
- data may be stale up to 15 minutes due to pipeline delay
- no trades returned if no qualifying whale activity occurred recently
- invalid query parameter type returns validation error

## How this service works

Polymarket whale trades and smart-money signals from the Predge tracking pipeline, sold per-call over the x402 payment protocol. No API keys, no accounts.

## Output

A list of up to 100 recent Polymarket trades of $10,000+ notional value, each including the market name, trade side (YES/NO), size, price, the trader's wallet address, and their Predge wallet score (0–100 scale reflecting 30-day win rate). Data is sourced from Predge's whale-tracking pipeline with a 15-minute delay.
