## 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-daily-whale-signals-by-category-f41df710
```

Example prompt: Pull today's Predge whale intelligence for the economics category — I want to see which Polymarket markets big wallets are piling into, the largest individual bets, and the wallet scores behind them.

## When to prefer this

Use this endpoint when you need a pre-aggregated, daily snapshot of whale activity scoped to a specific Polymarket category. It is the best choice when you want ranked market lists, wallet scoring, and bet-level detail in a single call without building your own on-chain analytics pipeline. Prefer it over raw blockchain queries or general crypto data APIs when the goal is prediction-market-specific whale intelligence with built-in heuristic insider detection.

## Known failure modes

- Invalid or unsupported category slug returns empty or error response
- Category with no whale activity in the 24h window returns zero-count totals
- Stale data if ingest pipeline is delayed — check generated_at timestamp
- 402 Payment Required if USDC micropayment not included or x402 header missing
- Historical/tag-less markets excluded from category slice — coverage is partial by design

## How this service works

Real-time alerts on whale traders on Polymarket. Heuristic Insider Watch, wallet scoring 0–100, Bloomberg-style web terminal. Free plan included.

## Output

A JSON object containing: aggregate totals (whale trade count, unique wallets, markets touched, total whale volume in USD), a list of top markets sorted by whale activity with yes/no volume splits and net flow, a list of the largest individual bets with wallet address, wallet score (0-100), 30-day win rate, bet side and price, transaction hash, and a timestamp for when the report was generated. Coverage note indicates partial category coverage for markets without tags.
