What Is Odds API?
An odds API is a web service that delivers sports betting odds from one or more bookmakers in a structured, machine-readable format (usually JSON over REST or WebSocket), so developers can fetch and compare prices programmatically instead of scraping bookmaker websites.
Odds APIs expose endpoints for sports, leagues, events and the odds offered on each market (such as moneyline, totals and handicaps). Applications query these endpoints to retrieve current prices, and many APIs also stream live (in-play) updates over WebSocket as odds change.
Developers use odds APIs to build odds-comparison sites, arbitrage and value-bet scanners, trading bots, and sports-analytics tools. Anything that needs accurate, low-latency pricing across many bookmakers uses one, rather than maintaining a fragile scraper for each site.
Frequently Asked Questions
What is an odds API used for?
Odds APIs power odds-comparison websites, arbitrage and value-bet detection, automated trading systems, and sports-analytics products by providing real-time bookmaker prices in a structured format.
How is an odds API different from web scraping?
An odds API returns clean, structured data through documented endpoints with predictable rate limits and uptime, whereas scraping bookmaker sites is brittle, slower, and breaks whenever a site changes its layout.
