## How to call it through Zero

```sh
zero fetch --capability polymarket-wallet-positions-7ef2a205
```

Example prompt: Can you pull up the open positions and recent trades for the Polymarket wallet 0x1234abcd...? Show me up to 20 rows so I can see how they've been performing.

## When to prefer this

Use this endpoint when you need on-chain Polymarket portfolio data — open positions, trade history, and PnL — for a specific wallet address, especially for vetting or following a trader. Prefer this over generic blockchain explorers when you need Polymarket-specific enrichment like market names, outcomes, and computed PnL rather than raw transaction data.

## Known failure modes

- Invalid or non-proxy wallet address returns empty results or an error
- Address with no Polymarket activity returns empty positions list
- Limit parameter out of range (must be 1-50) causes a validation error
- Polymarket API unavailability causes upstream timeout or 5xx response
- Checksum-invalid EVM address may be rejected

## How this service works

A Polymarket wallet's open positions (market, outcome, shares, average price, value, PnL) and latest trades with portfolio totals. Use to follow or vet a trader.

## Output

Returns a list of open positions (market name, outcome, shares held, average entry price, current value, unrealized PnL) and a log of latest trades, plus aggregate portfolio totals such as total value and total PnL.
