Polymarket Price History Scraper

🚀 Polymarket Price History Scraper

Get the full price history of any Polymarket market, from the day it opened to the moment it resolved. The Polymarket Price History Scraper exports one row per price point for every outcome, at 1-minute, 1-hour or 1-day intervals, with each row labelled with its market, outcome and resolution. It is built for researchers, data scientists and journalists who need clean historical odds.

✨ Features

• 📈 Full history, not just the last month: Covers the whole life of a market, including markets that resolved years ago.
• ⏱️ 1-minute, 1-hour or 1-day intervals: Minute data is available across a market's entire life.
• 🏷️ Outcome-labelled: Every point says which outcome it prices (Yes/No, candidate, team), with its token ID.
• ✅ Resolution included: resolved, winningOutcome and closedTime are on every row, so no second lookup is needed.
• 🗂️ Events expand to all markets: Paste an event URL (e.g. an election with many candidates) to get every market in it, up to Max markets.
• 📅 Date range: Limit history to a start and end date.
• 📋 Honest gaps: Missing periods are never filled in. RUN_SUMMARY lists each price series with its point count, largest gap and whether any history exists.

🛠️ How It Works

1. Enter markets: Polymarket event or market URLs, market slugs or condition IDs.
2. Pick an interval: 1 minute, 1 hour or 1 day. Optionally set a start and end date.
3. Run the scraper: Get one row per outcome per timestamp, ready to export as CSV, JSON or Excel.

💰 Pricing

Event	Price	When
Price point	$0.00002	Each price point saved

That is $0.02 per 1,000 points. A full year of daily prices for a Yes/No market (~730 points) costs about $0.015. A year of hourly prices costs about $0.35.

❓ Good to Know

• Prices are probabilities between 0 and 1 (0.58 = 58%).
• Markets from 2020–2021 have no price history. They are listed in RUN_SUMMARY with historyAvailable: false and are not charged.
• Quiet periods can leave gaps, especially on the less-traded side of a market. Check maxGapHours in RUN_SUMMARY.
• Daily points are taken at midnight UTC. The move on the day a market resolves shows up in hourly or minute data.
• One minute of data is about 1,440 points per outcome per day. Use a date range for long minute-level exports.
