## 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-market-whale-activity-baa2ae76
```

Example prompt: Pull up the whale trading data for Polymarket condition 0x1234...abcd — I want to see the YES/NO split, net flow, and how many big wallets have been active in the last 7 days.

## When to prefer this

Use this endpoint when you need detailed, aggregated whale trading intelligence for a specific Polymarket prediction market — particularly when assessing smart-money positioning, YES/NO sentiment, or net flow before making a trade or publishing analysis. Prefer it over generic on-chain analytics when you need Polymarket-specific whale heuristics and wallet scoring context.

## Known failure modes

- Invalid or malformed conditionId (not a valid 0x Polymarket condition hash) returns an error
- No whale activity found for the specified market returns empty trade list
- Market does not exist on Polymarket returns not found error
- Payment not included or insufficient USDC results in 402 payment required
- Rate limiting if too many requests are made in quick succession

## How this service works

Whale activity for one Polymarket market over the last 7 days (15 min delay). Path param: conditionId (0x… Polymarket condition id). Returns market info, aggregate whale volume, YES/NO split, net flow, unique whale wallets, and up to 200 trades.

## Output

Returns a JSON object containing market metadata, total whale volume over the past 7 days, YES vs NO volume split, net buy/sell flow, count of unique whale wallets active in the period, and a list of up to 200 individual whale trades with trade-level detail. Data is delivered with a 15-minute delay.
