## 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 polymarket-smart-money-consensus-signal-047bdff8
```

Example prompt: Show me today's smart-money consensus across Polymarket — which markets do high-score whale wallets have a clear YES or NO conviction on, and what's the net flow for each?

## When to prefer this

Use this endpoint when you need a quick, ranked view of where high-credibility whale wallets (Predge score > 70) are concentrating their bets across all active Polymarket markets, with a clear directional verdict. Prefer this over single-market whale endpoints when you want a broad market-wide signal rather than deep detail on one specific market, and over the raw whale trades endpoint when you want aggregated consensus rather than individual trade records.

## Known failure modes

- Insufficient data: returns {"insufficient_data": true, "reason": ...} when the scorer has not graded enough wallets yet
- No markets qualify: returns an empty or short list if fewer than top-50 markets meet the whale/score threshold in the 24h window
- Stale data: results reflect up to 15 minutes of lag from live trades
- Service unavailability: upstream Railway deployment may be temporarily down

## 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 sorted list of up to 50 active Polymarket markets where wallets with Predge score > 70 made trades >= $10,000 in the last 24 hours. Each entry includes YES volume, NO volume, net USD flow, count of distinct smart wallets, and a verdict of 'yes', 'no', or 'split' based on whether one side holds >= 55% of smart volume. Data has a 15-minute delay. If insufficient wallets have been scored, returns {"insufficient_data": true, "reason": "..."}
