Struct Polymarket Data API: Real-Time Indexing and PnL Analytics

Struct Overview

Struct Key features

• Unified REST API

  A single set of endpoints covers events, markets, trades, positions, trader summaries, and leaderboards. Materialized rows mean most queries resolve instantly, so you skip writing custom logic to combine multiple upstream sources.

• Real-Time WebSockets

  Streams push trades, price movements, position updates, and PnL changes within roughly 50 milliseconds of on-chain settlement. Mempool data is also available, giving earlier visibility than waiting for final block confirmation.

• Block-Level PnL

  The PnL engine tracks realized and unrealized components separately and includes every fee, rebate, yield, and reward that affects actual outcomes. The numbers reflect economic reality rather than simplified cost-basis snapshots.

• Event-Driven Webhooks

  Push notifications cover dozens of event types, including market creation, large trades, probability spikes, and PnL threshold crossings. Signed payloads let you verify origin, and built-in retry handling reduces the work of maintaining your own notification layer.

• Full Historical Index

  Struct has indexed Polymarket activity from its first contracts onward and supports initial loads at around 24,000 rows per second. This gives backtesting and machine-learning work years of depth without the cost of building or maintaining a custom index.

  bro i use @askginadotai website for trades but if u want to see ur stats then u can use @structbuild website. just add ur address in the end "https://explorer.struct.to/traders/"
  The PnL there actually includes fees and everything. Way better than the default view.

  Finally a dashboard that shows my real Polymarket PnL. After the latest update it tracks everything down to the block — fees paid, rebates, yield, the works. No more guessing whether I'm actually up or just seeing inflated numbers. Explorer makes it dead simple too.

  Integrated Struct's SDK and webhooks into my copy-trading setup last month. New market alerts and PnL crossing notifications hit instantly instead of the old polling mess. Latency is noticeably lower and the enriched trade data (fee splits, builder context) saves me a ton of extra calls. Solid foundation if you're building anything serious on Polymarket.

   We benchmarked @Polymarket RTDS feed against the Struct Trades WebSocket across ~15,000 live trades.
   Struct's confirmed feed leads by ~0.5s and mempool feed by ~ 2.6s.
   Take a deeper dive into the upgrade 👇

    What our portfolio has been up to this week:
    🔹 @FolksFinance went live with cross-chain WBTC and WETH on Algorand via Wormhole NTT, bringing native BTC and ETH lending to Algorand without a wrapper hop.
    🔹 @alloxdotai opened its largest campaign to date: $500,000 in rewards across six weeks, for on-chain portfolios built on BNB Chain via PancakeSwap.
    🔹 @structbuild shipped a full Polymarket Explorer upgrade, now covering market pages, liquidity rewards, recent trades, and category tags, all running on the Struct SDK.
    🔹 @KaspaCom launched its first stablecoin pool, with USDC live on the KaspaCom DEX, paired with liquidity rewards and 3x KCOM points for early LPs.
    🔹 @BitSafe_Finance CEO Aki Balogh joined FintechTV from the NYSE floor this week to unpack CBTC on Canton, and the thesis that institutional Bitcoin on-chain needs its own security model.
