## 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 blockrun-polymarket-wallet-pnl-lookup-1a79e455
```

Example prompt: Can you pull the Polymarket profit and loss history for wallet address 0xAbC123... and tell me how that trader has been performing?

## When to prefer this

Use this endpoint when you need on-chain Polymarket PnL data for a specific Ethereum wallet address, particularly in an agent workflow where x402 micropayment settlement in USDC is acceptable. Prefer this over manual on-chain queries when you need a convenient, pre-aggregated PnL summary without writing custom subgraph queries.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Zero-address (0x000...000) returns empty or placeholder data
- Wallet has no Polymarket trading history — empty PnL result
- Payment not settled or insufficient USDC balance — 402 Payment Required
- Rate limiting or API downtime returns 5xx error

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

Returns profit and loss data for the specified Polymarket wallet address, including realized trading gains and losses from prediction market positions.
