## 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 whale-radar-polymarket-wallet-intelligence-0f4d5198
```

Example prompt: Look up the open positions and last 20 trades for this Polymarket wallet 0x7a9dc87be2c72791fd86fad5f67be7c5dc89ba5d — include closed positions too so I can see the full picture.

## When to prefer this

Use this endpoint when you need on-chain Polymarket portfolio intelligence for a specific wallet — open positions, trade history, and position values — without needing a Polymarket account or API key. Ideal for whale-watching, competitor analysis, or monitoring a known trader's prediction market activity. Prefer this over generic blockchain explorers when you want structured, Polymarket-specific position and trade data rather than raw transaction logs.

## Known failure modes

- Invalid wallet address format (must be 0x-prefixed 42 hex chars) returns validation error
- Wallet address is not a Polymarket proxy wallet — no data found
- activity_limit or positions_limit out of range (must be 1–50) returns error
- Payment failure or insufficient USDC balance blocks the request
- Polymarket data unavailable or Polygon RPC issues cause upstream errors

## How this service works

Polymarket whale intelligence for a given proxy wallet address. Returns recent prediction-market trades (market title, outcome, side, size in USDC, price, timestamp) and current open positions (title, size, avg price, current value, unrealized PnL). Infers whale tier (whale/shark/dolphin/minnow) from trade sizes. Use for copy-trading signal generation, market-sentiment cross-reference, or on-chain agent behavior profiling. Free upstream: Polymarket public data API.

## Output

Returns a structured payload containing the wallet's open prediction market positions (up to the requested limit), recent trade activity (up to the requested limit), and position metadata such as market names, sizes, and values. Closed/redeemable positions are optionally included.
