Scrapes markets and events from Polymarket's public Gamma API with pagination and filtering. It can also fetch public price history (Yes/No odds over time) for each market outcome.

Example input:

{
  "status": "open",
  "maxMarkets": 250,
  "searchTerm": "election",
  "includeEvents": true,
  "includePriceHistory": false
}

Advanced input (optional): minVolume / minLiquidity (USD filters), priceHistoryInterval (Hourly / Every 6 hours / Daily / Weekly), historyStartDate / historyEndDate (YYYY-MM-DD), marketSlugs (keep only these slugs), outcomeTokenIds (fetch history for specific outcome tokens), and discoverMarkets (turn off to only pull price history for outcomeTokenIds).

Operational notes:

No authentication required — uses the public Gamma API at https://gamma-api.polymarket.com.
searchTerm keeps markets whose question or slug contains the text; minVolume / minLiquidity filter by USD size.
Markets include parsed outcomes, outcome prices, volume, liquidity, and outcome token IDs.
Events include nested market IDs and tags.
Price history uses the public CLOB /prices-history endpoint.
Pagination stops when a short page is returned or maxMarkets is reached.
