## 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-wallet-trade-history-api-fb685803
```

Example prompt: Pull up the full trade history for Polymarket whale wallet 0x8dab6cf42d7e4d1cd6cca897b9e12a8cbe6d69e8 over the last 90 days — I want to see their win rate, modeled P&L, and every market they've traded.

## When to prefer this

Use this endpoint when you need a comprehensive historical view of a single whale wallet's Polymarket activity — including per-trade details, running P&L, and a wallet quality score — rather than a top-level leaderboard or market-wide whale activity. Prefer this over the market-specific whale endpoint when the user is investigating a known wallet address rather than a specific market. Best when you want multi-market aggregated performance across a configurable time window (30d, 90d, or all-time) for one address.

## Known failure modes

- Invalid or non-existent wallet address returns empty trades array or 404
- Unrecognized window value (not 30d/90d/all) may return 400 or default behavior
- Payment not fulfilled via x402 protocol returns 402 Payment Required
- Address with no Polymarket activity returns empty summary and trades list
- Network or Railway infrastructure downtime returns 5xx error

## 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

A JSON object containing a list of individual trades (with fields: wallet, market title, market slug, condition ID, side, entry price, size in USD, resolution, whether the trade won, modeled P&L per trade, running modeled P&L, and 30-day win rate), plus a summary with total trade count, decided trades, wins, overall win rate, and aggregate modeled P&L. Also includes the queried address and window. A note clarifies that modeled_pnl_usd is an estimate, not settled P&L.
