Extract live Underdog Fantasy player props — over/under lines, American and decimal odds, payout multipliers, matchup metadata, and MLB pitcher/weather context — across 18 leagues with structured fields per row. Output field names align with the PrizePicks Player Props Scraper for cross-platform joins.

Designed for Underdog-only monitoring, model feeds, and as input to the DFS Multi-Source Props Scraper for line comparison.

When to use this Actor

Use the Underdog Fantasy Player Props Scraper when you need Underdog-only data — Higher/Lower odds per side, venue and weather fields, probable MLB pitchers — without pulling other platforms.

Underdog is typically the slowest source in the suite (CloakBrowser / Turnstile). For all platforms in one run, use the DFS Multi-Source Props Scraper.

Key Features

• Real-time odds — American/decimal odds and payout multipliers for Higher and Lower.
• CloakBrowser / replay modes — Stealth automation, browser cURL replay, HAR text, or raw JSON.
• US residential proxies — Required; Underdog blocks non-US traffic.
• MLB analytics — Probable starting pitchers, venue type, weather when available.
• Cost-optimized filters — Sport, player, market, and team filters before dataset push.
