## 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-whale-data-api-market-whale-activity-by-condition-id-5f7cf57c
```

Example prompt: Pull the whale trade activity for the Polymarket market with condition ID 0x178a746e2b342c25b1d78d0f0d0ea77157c9b6d40b2e97ffbf827cd7f9994c39 — I want to see which high-scoring wallets are buying YES or NO, the net dollar flow, and total whale volume over the last 7 days.

## When to prefer this

Use this endpoint when you need per-market whale and smart-money trade data for a specific Polymarket condition, including individual wallet-level signals with win rates and wallet scores. Prefer this over the top-movers or top-wallets endpoints when you already have a specific condition ID and want deep per-trade detail rather than a cross-market or cross-wallet ranking view.

## Known failure modes

- Invalid or malformed conditionId returns an error or empty result
- Market not found on Polymarket returns no data
- Payment failure via x402 protocol blocks the response
- Data delay of up to 15 minutes means very recent trades may be missing
- conditionId for a resolved or delisted market may return stale or empty trade arrays

## 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

Returns a JSON object with: (1) market metadata (title, status, category, yes_price, condition_id), (2) an array of individual whale trades each with side, price, wallet address, transaction hash, size in USD, wallet score, block timestamp, and 30-day wallet win rate, and (3) a summary with net_flow_usd, whale_trades count, yes/no volume USD, unique_wallets, and total whale_volume_usd — all covering a 7-day window with a 15-minute data delay.
