Track what any Polymarket wallet is buying and selling — point your agent at a smart-money or whale address and get its public trades as a signal feed for copy-trading or market research, with no Polymarket account or API key. Reads the official account-free Polymarket Data API (data-api.polymarket.com/activity) for one strict 0x wallet address; optional bounded limit (default 25, max 100), offset (max 10,000), activity type, BUY/SELL side, start/end unix-second window, sortBy, and sortDirection. Returns sanitized activity rows — each with type, side, size, usdc_size, price, outcome, market title and slug, transaction hash, and unix timestamp — and drops name, pseudonym, bio, and profile images. Read-only; Fabler Labs is not affiliated with Polymarket; no betting execution, custody, or wager recommendation. Upstream failures, timeouts, oversized responses, and malformed or drifted schemas return non-2xx and do not settle.
