PolyEdge Polymarket Mempool Streaming And On Chain Analytics API

PolyEdge Overview

PolyEdge Key features

• Mempool Trade Stream

  Subscribe through Server-Sent Events to matched Polymarket orders before they reach finality. The stream includes transaction data, market details, taker information, and matched maker fills.

• Low-Latency Data

  PolyEdge peers with more than 100 Polygon validator nodes to surface trades ahead of block inclusion. Published benchmarks report a median lead of more than two seconds over on-chain block time.

• Smart Money Rankings

  Rank active wallets by net profit, return on investment, win rate, or markets traded. Filters cover time periods and categories such as sports, crypto, and politics.

• Wallet Performance Data

  Review wallet profiles, market results, and individual order fills. Profit figures account for trading fees and include details such as price, size, side, and maker or taker status.

• Market Context

  Stream events and analytics responses include market questions, condition IDs, slugs, tags, and series data. Most downstream apps can use this context without extra lookups.

• Exact Maker Attribution

  Each matched trade lists the resting maker orders and their fill quantities. This gives copy trading and liquidity analysis more precise data than inferred totals.

• Fee-Adjusted Analytics

  The analytics engine subtracts protocol fees from each fill and resolves collateral redemptions for closed positions. Users can review realized results by market, tag, or series.

• Developer SDKs

  Official SDKs support Node.js, Python, Rust, and Go. They include endpoint methods, stream access, reconnection handling, and typed responses where supported.

• Read-Only Access

  PolyEdge does not place trades, hold funds, or request private keys. Users authenticate with an API key sent through the X-PolyEdge-Key header.

• Polygon Coverage

  The service covers Polymarket version two activity on Polygon. It does not support other blockchains or earlier Polymarket activity.

PolyEdge Fees

• Free trial Historical announcements mention a free trial lasting several days with no credit card required.
• Paid tiers After the trial, access moves to paid tiers with demo, individual, and professional levels.
• Tier limits The tiers limit pagination depth, result limits, and optional fields such as full order inclusion.
• Trading fees PolyEdge does not charge its own trading fees, while analytics include protocol fees already charged by Polymarket.
• Current pricing Exact monthly or usage-based costs require contacting the operator or signing up to view current plans.

How to use PolyEdge

1. 1

   Create an account

   Visit polyedge.dev and create an account. Use the account dashboard to obtain your PolyEdge API key.

2. 2

   Store your API key

   Copy the key and save it in an environment variable or secrets manager. Treat the key as sensitive and do not place it in public code.

3. 3

   Set the request header

   Add the key to every request with the X-PolyEdge-Key header. Check the documentation for the exact header format and endpoint details.

4. 4

   Query the leaderboard

   Call the leaderboard endpoint with filters such as time window, category, return, win rate, or number of markets. Review the ranked results and copy a wallet address for deeper analysis.

5. 5

   Inspect trader activity

   Use the wallet address with the profile, markets, and orders endpoints. Review performance, market-level results, fills, fees, sides, prices, and maker or taker status.

6. 6

   Connect to the stream

   Open a Server-Sent Events connection to the mempool stream endpoint. Add filters for trader addresses, market tags, series slugs, trade size, share quantity, or price range when needed.

7. 7

   Process incoming fills

   Read each stream event in your application and use its transaction hash, market details, taker data, and matched maker orders. Update local state or trigger your own alerts and trading logic when new fills arrive.

8. 8

   Install an SDK

   Install the Node.js, Python, Rust, or Go SDK if you prefer a language-specific client. Initialize it with your API key and use its methods for the same endpoints and stream connection.

9. 9

   Monitor account usage

   Check the account telemetry endpoint for request volume and watch your tier limits. Adjust polling, pagination, or stream usage if your application approaches its limits.

10. 10

    Review the documentation

    Use the PolyEdge documentation to confirm available parameters, response fields, reconnection behavior, and error codes before deploying your integration.
