Polymarket Prediction Market & Wallet Monitor

Track live Polymarket prediction markets and the recent trading activity of wallets you choose. Every run returns a current market board — question, outcome prices, end dates, lifecycle flags and tags — and, when you add wallet addresses, their recent fills with buy/sell side, shares, price, USDC value, market context and timestamp.

Use it for prediction-market research, odds dashboards, event monitoring and wallet-activity feeds. Results arrive as a dataset with one record per market or per wallet fill, plus a run summary. The data is public market information, so no sign-in is required.

Quick start

Collect the current market board and the last 24 hours of fills for one wallet:

{"wallets":["0xd9c9651bfd445b2cddf750662ee79a755f216686"],"lookbackHours":24,"maxMarkets":200,"maxPages":6}

Leave wallets empty for a market-only run.

Input

Name	Type	Default	What it does
wallets	array	[]	Wallet addresses whose recent fills to collect.
lookbackHours	integer	24	How far back to keep wallet trades (1–336 hours).
maxWalletTrades	integer	100	Most recent trades fetched per wallet (1–500).
activeOnly	boolean	true	Keep only markets that are active and not closed.
acceptingOrdersOnly	boolean	false	Keep only markets that are accepting orders.
tag	string	empty	Keep only markets carrying this tag, such as sports.
maxMarkets	integer	200	Maximum market records returned (1–2000).
maxPages	integer	6	Maximum market pages fetched (1–30).
telegramChatId	string	empty	Optional chat for a large-trade digest. Requires the TELEGRAM_BOT_TOKEN environment variable.
alertMinUsd	number	100	Trades at or above this USDC value go into the digest.
requestDelaySecs	number	0.25	Pause between wallet requests, in seconds.

Very restrictive filters can return fewer records or none; the run summary explains why (for example, the page budget was reached).

Output

Every row is either a market or a wallet trade. Market rows carry the question, market slug, lifecycle flags, end date, tags, trading rules and outcome tokens with their prices. Wallet rows carry the wallet, side, shares, price, USDC value, outcome and trade timestamp.

One market row — selected fields from a real 2026-09-06 snapshot; prices are historical, not current quotes:

  "question": "Manchester City FC vs. Norwich City FC: O/U 7.5 Total Corners",
  "marketSlug": "efl-mnc-nor-2026-09-17-corners-total-7pt5",

}

One wallet-trade row:

  "title": "Will Málaga CF win on 2026-09-06?",
  "tradedAt": "2026-09-06T15:14:58+00:00"
}

Unpublished values are returned as null rather than guessed. A run summary in the key-value store reports the status, record counts, coverage and any warnings.

FAQ

How fresh is the data? Each run reads the current market board and the newest available wallet fills.

What limits apply? Up to 2,000 markets, 500 trades per wallet and 25 wallets per run.

Can I focus on one topic? Yes — filter by tag, activity and order acceptance, and cap the markets and pages collected.

What if a wallet has no recent trades? The market board is still returned and the run summary notes the empty wallet lane.
